Coloring plastics at the press is one of the most functional, value-added features a molder can impart to a molded product. Self-coloring not only improves aesthetic properties, it can also Excellerate UV stability and make processing easier. Also, adding color at the machine is almost always less expensive than purchasing precolored material from a supplier.

There's just one catch. Once the color system has been incorporated into the polymer matrix, it becomes an integral part of the material and may alter its engineering properties as well as its processability. As a result, it's important to be aware of some of the common problems involved with melt-coloring plastics and how to avoid them.

Generally, aesthetic flaws can be attributed to three different causes: equipment (machine, mold, ancillary equipment), molding (process), and design (part and tool)/formulation (base resin and colorant). In some instances, the flaw may be the result of problems in more than one category, but generally, there is always a predominant issue. Similarly, some problems may have more than one symptom, so several different "problems" may be showing up in parts that have the same root cause, which calls for the same corrective action.

When troubleshooting aesthetic problems in molded parts, it's important to begin with an open mind. Since successful molding is an interdependent combination of machinery, labor, material, and design, troubleshooting is often more complicated than people initially expect.

Identifying the Problem
The first step in determining if the flaw is caused by a molding- or colorant-related problem is to inspect parts visually to determine what the problem looks like. Some flaws are very distinctive and quickly lead you to their root cause. Others are less distinct and may be caused by a number of factors that fall into several categories. Consequently, some basic troubleshooting and root-cause/corrective-action work is required. The table with this article provides a list of common aesthetic flaws that could involve colorant and their most probable causes.

The next step is to find out when and where the flaws are being reported. Flaws that show up immediately upon molding require one approach to troubleshooting-for instance, processing and equipment issues are easier to check at this point. In this case, the troubleshooting process might start by asking the following questions:

  • Have the process settings changed?
  • How frequently does the problem occur?
  • Is the proper equipment in place and functioning?
  • Was the colorant properly metered in and mixed with the melt?
  • Is the colorant compatible with the base resin?

However, field failures that occur after months or even years will suggest a different starting point-a focus that begins with either part design or formulation:

  • Is UV exposure higher than initially predicted?
  • Is the part being used as originally designed?
  • Has the part been inadvertently exposed to some chemical agent?
  • Is the aesthetic change a symptom of a larger problem (for example, loss of mechanical properties)?

Regardless of the simplicity or complexity of a molding project, good documentation practices should be in effect and followed diligently by all team members. Processing parameters should be noted throughout. Not only will this practice help molders stabilize their process and create good parts faster, it will also provide a baseline for reference should the process drift and problems arise.

Common Sense- Often Uncommon
The best way to begin troubleshooting an aesthetic problem in which colorant and/or special-effects packages are involved is to rule out the colorant package as the source of the problem. This is done by running uncolored (natural) material through on the same process settings to see if the problem recurs. If it does reappear, then it's likely that the problem is not caused by the colorant package, although the base resin could still be part of the problem. If the problem disappears, then the colorant package is the proper place to begin your investigation. It's important to remember that aesthetic issues may exist that are difficult to see without color. In other words, a colored background will frequently magnify aesthetic problems.

While it is outside the scope of this article to cover the entire process, one thing that should be mentioned is that proper troubleshooting requires a sensible, methodical approach. Unless a Taguchi design of experiments study is being conducted, only one parameter at a time should be changed, and its effect should be carefully evaluated and documented. Then the parameter should be returned to its baseline setting before another parameter is changed.

While the following guidelines involve colorant-related problems, we will also touch briefly on processing, equipment, and design issues, indicating areas of concern that can affect colorant and/or aesthetics. If the troubleshooting process indicates that one of these categories is a likely cause, then there are a number of good resources, both human and written, that can and should be consulted for further help.

Troubleshooting Guidelines

As with any manufacturing process, molding a quality product consistently requires proper equipment, design, material, and processing procedures. The following list of considerations are provided as general guides when beginning to troubleshoot aesthetic problems.

1. First, check the following four equipment areas.

Screws/nonreturn valves. In most cases, a general-purpose screw will work well with colorants, depending on the letdown ratio, chromaticity, and base resin used. Although it's usually not necessary, a growing number of injection molders are using mixing screws to aid in color distribution. Processes with high throughput, short cycle times, and large shot sizes or those that use difficult-to-color resins will often benefit from this type of screw.

As with screws, selection of non-return valves is often resin-specific. Ball check valves are more shear intensive and can aid in color distribution, although this method can prove problematic when processing parameters such as screw speed, backpressure, and barrel temperatures are pushed close to the base resin's limits, leading to both colorant and resin degradation.

Screw and barrel wear. A worn screw or barrel-regardless of the design-will inhibit mixing, causing a loss in plasticating quality and therefore color distribution.

Barrel capacity. As a general rule, using more than 60 percent of the barrel capacity with a GP screw is considered to be pushing the processing envelope for good color incorporation. Of course, this is cycle-time dependent. The barrel's L/D ratio is also important. For example, shorter barrels (18:1) are less conducive to a good mix, while longer barrels (24:1) provide a longer mix environment, but also longer residence time. It's important to keep an eye on material residence time, because excessive residence can degrade either the base resin or the colorant, or both, while insufficient time in the barrel may lead to distribution issues.

Colorant handling and dispensing. One of the keys to successful color processing is an accurate blending/distribution of colorant and base resin before both enter the molding machine. When blending equipment is used, production personnel must be aware of proper operation, calibration, and maintenance. If the equipment is not properly calibrated to the process, any money saved by coloring the raw materials will be lost in wasted product.

For solid (salt and pepper mix) colorants, there are many different options, such as drum tumblers or auger mixers. For blending concentrates and powders at the machine, either volumetric or gravimetric feeders are used. Volumetric feeders are both less expensive and potentially less accurate than gravimetric types because they feed colorant based on speed vs. time. Gravimetric feeders weigh and blend each component in the mix. For liquid colorant, special volumetric pumps are typically used to handle the color accurately and neatly. (See the sidebar on p. 87 for definitions of common colorant-system formats and their functions.)

2. Tooling design can also impact aesthetics.

Gates and runner systems. Proper gating and runner types should be considered at the design table. It's important to remember that additional heat generated by a hot manifold or pin gate during injection fill can affect the integrity of the color. If it's known ahead of time that such tooling is being used, a colorant supplier can formulate the color package differently.

Knitlines. Anticipating aesthetic issues during the early design stage is very important, especially if knitlines are a factor. When moldfilling analysis or experience indicates knitlines are likely, color formulation changes can be made with certain resin families that will Excellerate the appearance of knitlines. Of course, this issue is more easily resolved during the early stages of part and tooling design.

Mold texture. Also an important consideration during the design stages is mold texture, since it can affect how the eye perceives color. The presence of gloss and/or texture in the tool can make what would otherwise be an exact color match appear very different. Gloss should be considered in relation to both the mold and resin being processed, since some materials naturally have higher gloss.

3. Take a good look at part design.

Color/special effects. It's important to understand that a joint blessing and challenge of molding color and/or special effects is that the color package may accentuate design or molding problems that are already present in a part, such as knitlines, slight sinks, or stress-whitening marks near the base of a snapfit. Taking color back out and running the part in natural resin may appear to make the problem disappear, but in reality the problem, if it is a molding or design issue, is probably still there, and just not as visible.

The problem will be accentuated in chromatic colors and high-gloss designs. So if it's something that can otherwise be lived with, slight design modifications may solve the problem. On the other hand, certain problems, like stress-whitening marks, can often be hidden by the correct use of color or possible reformulation.

When integrally colored, molded parts of dissimilar materials are mated with other molded or painted parts, they must often match in color, gloss, and texture. Here, it's important to work closely with the resin and color suppliers to ensure that the parts will match as closely as possible when they are new and that they will fade at the same rate throughout the lifetime of the assembly.

Bosses/ribs/knitlines/parting lines. Wherever there is a flow interruption in the part design-from bosses, ribs, or even converging flow fronts on multiple gated parts-there is a strong possibility of sink marks, knitlines, and compromised mechanical integrity because knitlines are always weaker than the surrounding resin. Since the orientation of the material in these areas shifts, the refractive index across this region of the part will also shift, posing aesthetic challenges for many special-effects packages. Therefore, these interruptions should be designed into nonvisible faces and noncritical areas of the part.

4. Take these processing tips to heart.

Screw speed. For color processing, a slower screw speed is usually better to avoid shearing and burning the colorant and to ensure proper color distribution, cycle time permitting.

Backpressure. Higher backpressure promotes more thorough mixing, especially with a GP screw, again, if cycle time permits. A maximum value of 300 psi (2 MPa) is generally recommended by machinery OEMs.

Resin temperature. Higher melt temperatures also promote better mixing, as long as the processor is careful not to begin melting too early in the feed section of the screw, although this too can be resin dependent.

5. Be aware of these colorant and formulation issues.

Resin and colorant compatibility. The melt index relationship between the base resin and color are very important and should be considered early in the design. Additionally, certain pigments react with particular resins to a greater or lesser degree.

For instance, some organic pigments tend to dissolve and disappear (or change color) in styrenic polymers. Similarly, many dyes tend to change color or disappear in nylon polymers, which are weak reducing agents that effectively destroy the chromophore component of the dye that provides color. Additionally, except in special cases, dyes are not recommended for use in olefins because of very limited solubility and a potential for color migration (crocking). Further, dyes can act as a plasticizer in some materials, reducing thermal properties or even reacting with the resin itself to produce various effects.

Phthalocyanine (phthalo) pigments can be problematic, since they can act as nucleators, causing often uncontrollable shrinkage and warpage problems in crystalline resins. Fluorescent dyes also can pose problems in certain environments. They lack thermal stability for use in many engineering resins, they chemically react with nylon, and they lack UV stability for use in most outdoor applications.

A final category of problems is often found with polymer blends and alloys. There can be phase boundaries between the various components of these materials that can cause light scattering and a resulting milkiness. Hence, obtaining chromatic colors can become a costly undertaking due to the large amount of colorant that needs to be introduced to counteract the milkiness-often at the expense of economic concerns and critical physical or mechanical properties.

Carrier specification. The specific carrier for the color and its flow properties vs. the base resin play an important role in color distribution, and must be considered during the initial design. The carrier should melt in the late-feed or early-transition sections of the screw to ensure proper distribution of the pigment or dye in the mix. If the carrier has either too high or too low a melting point, the colorant will not be properly distributed in the melt, and finally in the molded part.

Other additives. Special additives for the colorant package can help with some color-related problems. However, these ingredients are normally not incorporated until processing efforts have failed, primarily because they add cost that may make the end product less cost-effective.

Grade can make a difference. It's important to remember that not all resin families or even grades within the same family are interchangeable with a given color package, let alone with different pigment or dye packages in the same chemical family. Further, since most colorant suppliers custom formulate their packages to a specific resin grade by a particular manufacturer, if the resin supplier is switched after the color package has been formulated, it should be retested.

A good example of this is the fairly wide fluctuation that can be seen in the natural color of polypropylene, which can range from a yellow-white to a gray-white shade, depending on the quality and quantity of filler used.

An Ounce of Prevention
Like so many other problems in life, colorant issues are far easier to anticipate and prevent than to cure once they've occurred in molded parts. If color is important to the final performance of an application, then it should be designed in from the start via simultaneous engineering. To ensure the colorant package is properly formulated for the application, provide the color formulator with all available information on both the application and its material targets as soon as they are set.

If any of these specs change during the latter stages of the design process, inform both the resin and colorant suppliers. Changes may require a new formulation. Don't hesitate to call on the colorant supplier to analyze, retest, and reformulate a color formulation to make sure it will be suitable in the end-use environment.

It's also important to inform the colorant formulator of your equipment setup, in case you need to make changes in order to optimize the resin/colorant/throughput requirements of a particular application. Finally, watch your process parameters and once the process has stabilized, note any sudden changes that may signal the beginnings of a problem.

Special care is needed when self-coloring engineering resins because a significant portion of their perceived value-and therefore cost-lies in their superior physical, mechanical, and aesthetic properties, which can be sensitive to even small compositional changes. The more important color is in a given application, the sooner the colorant supplier should be involved in the design process.

Mac 
  • MacOS 10.12 to 11.1
  • iOS: 11.0+ (iPad only). Must have a compatible LMS integration.
  • 200MB permanent space on the hard drive.
  • Safari must be in proper working order. 

If you experience errors while taking a test through the LockDown Browser, check your security settings in IE and the overall functionality of IE. IE should be reset to default security levels, and the exam should be tried again.

The following tips may help to correct other problems encountered with Lockdown Browser.


Important Note: Non-testing Purposes

Only use Respondus LockDown Browser for testing purposes.

If you attempt to use the browser to access additional course content, like lecture notes or worksheets, it may cause the program to encounter a problem and freeze or close. This usually occurs when the content you are attempting to access is a Word, PowerPoint or Adobe Acrobat related file. The browser cannot open the external program needed to run these files because of the browser’s restricted nature and it creates an internal error with the software. If you need to view these files, please use a regular browser like Mozilla Firefox.


Problems Downloading and Installing the LockDown Browser

If you are having problems installing LockDown Browser on a Windows system, we recommend the following additional steps:

  1. Directly log into a system as a local administrator with full rights. Do not use “Switch User” or a “Remote Access” connection.

    Important Note:

    Logging in as a non-administrator and then using “Run as Administrator” may not set the correct permissions.

  2. Temporarily disable all security software. Contact the IT Help Desk for additional assistance in disabling your security software.
  3. Download Respondus LockDown Browser. Do not “Google” for a link because these are campus specific.
  4. When you start running the installer and get to the large button “LockDown Browser Click to install”, instead click the link “Problems with the installation program? Click here”. You will be presented with an option to extract the files to a location of your choosing.
  5. Go to the folder you extracted the files and run “setup.exe”.
  6. Start the LockDown Browser to verify installation and then quit the LockDown Browser.
  7. Re-enable any security software.

Because the LockDown Browser is a shell that sits on top of an Internet browser (Internet Explorer for PC users and Safari for Mac Users), we recommend students access their course with either Internet Explorer or Safari and take a non-LDB enabled practice quiz to resolve any settings and media plug-ins prior to taking a test with LockDown Browser.

For Windows systems, we suggest relaxing any security settings to “medium”, add “LockDown.exe” as a trusted application and “*.uwyo.edu” address as a trusted site in any security software.

Using LockDown Browser on a Wireless Connection

We strongly recommend using an Ethernet (wired) Internet connection with a speed of at least 512 Kbps or higher while taking your exam in LockDown Browser. If you use a wireless, USB modem, laptop connect card, or mobile hotspot connection during an exam, you are more likely to run into problems due to dropped/interrupted connections to the Canvas server. This is because the Canvas server is more bandwidth intensive (especially during exams) than normal Internet surfing.

If you lose your Internet connection during the exam, it will lock up the browser and not allow you to save answers, move on to other questions, submit or exit the exam. Ethernet connections are the most stable connection to the Canvas servers. If you have a router, plugging directly into it when taking exams will reduce the chances of connection interruptions.

Permissions Errors in LockDown Browser

If you are getting an error when you attempt to open the LockDown Browser that says “You may not have the appropriate permissions to access the item”, it may be an issue with the permissions on your system or antivirus software.

Respondus LockDown Browser uses the same HTML engine, system components and settings as Internet Explorer (Windows) and Safari (Macintosh). Basically, LockDown Browser provides a custom interface for the Internet Explorer (Windows) or Safari (Mac) browsers that are already installed.

We recommend completely uninstalling the software and doing a new installation while directly logged into the system as a local administrator with full rights (see instructions above for full details).

Link is Blocked Error

This occurs when there is a second level link being accessed from a primary level link. However, link blocking usually does not occur until the student enters a quiz and starts accessing links within a quiz. Usually, this comes from configuration issues with the underlying Internet Explorer browser components.

To resolve this issue, please try the following:
  • Start Internet Explorer and first go to Tools.
  • From the Tools menu, select Internet Options.
  • Inside the Internet Options dialog box under the General select Browsing History.
  • Hit Delete to clear the browser cache and related areas.
  • Finally, if you are running any third-party toolbars or add-ons, remove them from Internet Explorer.

LockDown Browser and Other Programs

The LockDown Browser is programmed to detect when conflicting programs are still running and will request that you close these programs. Some programs like the Dell Dock and Google Toolbar run as a background process on your computer and will have to be shutdown before you can proceed in the LockDown Browser. You can usually turn these programs off through the task tray or, in the case of the Dell Dock, by right clicking on the application and clicking Exit.

In some rare instances, these programs running in the background can cause the LockDown Browser to lock up or stop responding. Programs that use Java or the Internet such iTunes and other media managers, file sharing agents like Bittorent, and instant messenger applications have a higher risk of causing the LockDown Browser to lock up. It is best to close every program on your computer before starting the LockDown Browser.

LockDown Browser and Pop-Ups

If the LockDown Browser stops responding before you start an exam or if you see a blank page that fills the computer screen, this could be due to security windows that have popped up behind the LockDown browser. If you have not started the exam, close the browser and address the security pop-up windows. You should be able to reopen the browser without issue. However, if you have started the exam, the only known workaround is to restart your computer and address the pop-up windows before beginning the exam.

LockDown Browser Stops Responding

If you lose your Internet connection while taking an exam or if you have outdated and/or multiple Java installations, the LockDown Browser and your computer may stop responding or freeze. Currently, the only way to resolve this issue is to do a hard shutdown (i.e. unplugging all power from the computer including power cables and/or batteries if you are using a laptop). If you are missing your Start Menu, Task Bar or are unable to access the Task Manager after doing a hard reboot, you can restore these applications by restarting the LockDown Browser and exiting the software properly.

Depending on your system, this could take several minutes and will cause you to lose time on the exam. In most cases, as long as the time has not expired, it should let you back into the exam. As soon as you have completed the exam, immediately e-mail your instructor to let them know what happened.

LockDown Browser Updates

Occasionally, Respondus will release a new version of the LockDown Browser. When a new version of LockDown Browser becomes available, the system will prompt you to update your installation of the software.

Whenever you update your LockDown Browser, you may also want to do the following:

  1. Make sure your system is up-to-date by installing all necessary system updates. You will also want to make sure you have the latest version of Internet Explorer for Windows users and Safari for Mac users.
  2. Make sure you only have one version of the most exact Java installed on your system.

Important Note:

Macintosh users should be aware that Apple supplies their own version of Java for all operating systems prior to OS X 10.7 Lion. For Macintosh operating systems prior to Lion, use the Software Update feature (available through the Apple menu) to check for Java updates.

Killexams : Windows Startup & Boot problems – Advanced Troubleshooting

Are you an IT admin and need to troubleshoot Windows boot problems? If the answer is yes, then in this guide, we will share advanced troubleshooting for Windows 10 startup and boot problems. Before you begin, we recommend you check out our following post:

If the basic troubleshooting there does not help you, read on!

Windows 11/10 Startup & Boot problems

Windows 10 Startup & Boot problems

Boot Phases of a Windows computer

When you push the power button, the boot process goes through many phases. Before we go ahead and troubleshoot the problems which occur during the stages, let’s first get to know about them, and what happens during the process.

Phase Boot Process BIOS UEFI 
1 PreBoot MBR/PBR (Bootstrap Code) UEFI Firmware
2 Windows Boot Manager %SystemDrive%\bootmgr \EFI\Microsoft\Boot\bootmgfw.efi
3 Windows OS Loader %SystemRoot%\system32\winload.exe %SystemRoot%\system32\winload.efi
4 Windows NT OS Kernel %SystemRoot%\system32\ntoskrnl.exe

1]  PreBoot

When you hit the power button, the computer firmware starts POST or Power-On Self test and loads firmware settings. It checks if there is a valid disk system to start the next phase. It’s indicated by an MBR or master boot record. The PreBoot process then starts the Windows Boot Manager.

2] Windows Boot Manager

The job of Windows Boot Manager is simple. It loads another program -Windows Loader, popularly known as Winload.exe. Its located on the Windows Boot partition.

While it may seem to be a redundant process, the primary reason it exists is to help you boot into the right OS. When you have multiple OS installed on the same computer, it makes sure to load the right Winload.exe.

3] Windows OS Loader

Windows OS Loader now loads essential drivers to start the Windows kernel. The Kerner finally does the rest of the thing to deliver you an OS where you can work.

4] Windows NT OS Kernel

In the last stage, Windows NT OS Kernel picks up the system Registry hive, and additional drivers mark in the BOOT_START list. Then the control is passed on to the session manager process (Smss.exe). The System Manager in turn initializes the system session and loads up the rest of the hardware and software needed.

Advanced troubleshooting for Windows boot problems

If you are still wondering why so many phases, then my best guess is that it’s intentional. Imagine if it were just one program, it would have been almost impossible to figure out where exactly the problem occurred. Let’s finally start with the troubleshooting.

1] The Computer repeatedly boots to the recovery mode

When you turn on the computer, and it boots into the recovery option every time, we will have to use the Bcdedit program to break the loop.

  • Click on Troubleshooting > Command Prompt
  • Type Bcdedit /set {default} recoveryenabled no and hit Enter.

If the F8 options (Windows Safe Mode) don’t work, set the Safe Mode to work in legacy mode. Use the following command Bcdedit /set {default} bootmenupolicy legacy

2] Windows stuck with a blank monitor with no activity

BIOS phase is where the system goes from PreBoot to Loading Windows OS. It’s only marked as complete when there is no hardware issue in the system. So to check if it is a hardware issue:

  • Remove external hardware and boot again.
  • Check if your hard drive is working. If it’s too silent or there is no blinking LED, it’s probably dead.
  • If you cannot check that, press the Num Lock or Caps Lock to check if the indicator light toggles on and off.

3] Windows stuck at a blank monitor with a blinking cursor or an error message

When you get to see just a blink of an error message, then there is a problem with the Boot loader phase. The error message can include corruption of BCD/MBR boot sector/Bootmgr or missing OS or not being able to boot due to system hive missing or corrupted.

Startup Repair tool

This tool is available under the Advanced Options of Windows Recovery option. It can diagnose the logs, and fix complex startup problems automatically which does not let the computer boot properly.

  1. Create an installation media of the same version of OS installed on the computer.
  2. When you reach the Install Windows screen, click on Repair your computer link.
  3. Shutdown after the repair is complete.
  4. Next, turn on your PC to see if Windows can boot properly.

To analyze further, you can take a look at the log generated by the Startup Repair tool. It is located at %windir%\System32\LogFiles\Srt\Srttrail.txt

Repair Boot Codes

If you are stuck with the MBR boot sector error message, run the following in the Command Prompt. You can open it from Advanced Options of Recovery.

  • To repair boot codes, run the following command – BOOTREC /FIXMBR
  • To restore the boot sector, run the following command – BOOTREC /FIXBOOT

BOOTREC can only fix the Master Boot Record. If there is a problem with the partition table, it will not help.

Fix BCD errors

If you received BCD-related error, you need to use the Bootrec command to fix the issue.

  1. Execute the Bootrec /ScanOS command to scan for all the existing systems installed on the computer.
  2. Restart, and check if the problem is there no more. If no, then execute with rebuild option, i.e.  Bootrec /rebuildbcd

If you receive an output that says Total identified Windows installations: 0, run the following commands:

bcdedit /export c:\bcdbackup

attrib c:\\boot\\bcd -h -r –s

ren c:\\boot\\bcd bcd.old

bootrec /rebuildbcd

Once the execution is complete, you should receive a success message as Total identified Windows installations: 1{D}:\Windows. It will then ask “Add installation to boot list? Yes/No/All”,  Enter Y. Reboot and see if this Windows boot problems tip resolved the problem.

Replace Bootmgr

If the above solutions didn’t fix the problem, it’s time to replace the Bootmgr file from drive C to the System Reserved partition. To do this, follow these steps:

  1. Go to the Command Prompt via Advanced Options.
  2. Change the directory to the System Reserved partition and run attrib command attrib-s -h -r.
  3. Do the same in the system drive, i.e., where Windows is installed.
  4. Rename the Bootmgr file as Bootmgr.old with ren c:\\bootmgr bootmgr.old
  5. Copy the Bootmgr.Old file to the System Reserved partition.
  6. Rename it back to bootmgr.
  7. Restart the computer.

Restore System Hive

When you receive an error where it says that Windows cannot load the system registry hive into memory, then you must restore it from an alternate backup location.

You can either use the advanced startup or Emergency Repair Disk (ERD) to copy the files from the C:\Windows\System32\config\RegBack to C:\Windows\System32\config. It will almost, reset the registry to a different time where everything was working fine.

Killexams : How to Troubleshoot a Maytag Dishwasher Not Filling With Water

Maytag dishwashers come equipped with an overfill protection device. The overfill protection float -- depending upon your model -- is found in the front right or left corner of the tub. The float shuts the water off in the dishwasher to protect it from overfilling. If the float becomes trapped in a raised position, water will not enter the dishwasher. Remove the bottom tray in the dishwasher to get at the cylindrical float. Detach the screw and bracket at its back with a screwdriver that holds a cover over the float. Lift the cover from the float. Test it by tapping on it lightly. If it does not move, remove trapped food, utensils or obstructions that keep it locked in position. If it has free movement, the switch that powers the float could have failed. Listen for a clicking noise as you tap the float. If it clicks, it is probably fine; if not, you will need to replace it to get the dishwasher to fill with water.

Killexams : 2 Quick Ways to Troubleshoot Audio Issues on Your Xbox © Provided by MUO

You can experience audio problems on every gaming platform. With issues stretching from audio quality to how your TV setup may affect audio, it can be challenging to pinpoint and correct the problem.

Luckily for Xbox users, Microsoft has implemented two quick and easy ways to troubleshoot the most common audio issues you may be experiencing. If you are experiencing problems with audio, we can guide you through these quick and easy ways to troubleshoot.

Troubleshooting Audio Issues on Xbox

If your issues are with audio quality or hearing no sound, the quickest and easiest way to troubleshoot is to check your TV and HDMI connections or run the Audio Setup options on your Xbox console.

Checking TV and HDMI Connections on Xbox

One of the most common causes of audio-related issues on Xbox is your console not connecting to the correct audio output source.

A quick and easy way to fix this is by ensuring your Xbox's display settings are set to your HDMI port. To ensure your display settings are set to HDMI, follow these steps:

  1. Press the Xbox button on your controller to open the guide menu.
  2. Scroll right to the settings for Profile & system and select Settings.
  3. Within the General tab, select TV & display options.
  4. Select Video fidelity & overscan.
  5. Under Display, open the drop-down menu and select HDMI.

Manually selecting the display output for your console to HDMI should ensure that any device you have your Xbox connected to through an HDMI cable will be the primary output source for any audio.

If your HDMI cable works fine through other devices, your Xbox console or display may be non-functional. If this is the case, you may want to look into the best HDMI 2.1 gaming TVs to replace any faulty hardware causing your audio issues.

How to Run an Audio Setup on Your Xbox Console

Using the Audio Setup options on your Xbox console will help identify if any external speaker or output device isn't working as it should in your setup.

To run the Audio Setup option on Xbox, follow these steps:

  1. Press the Xbox button on your controller to open the guide menu.
  2. Navigate to the settings for Profile & system and select Settings.
  3. Within the General tab, select Volume & audio output.
  4. Under the Advanced options, select Audio Setup.
  5. Once Audio Setup is running, it will show you each audio option available for your setup.
  6. Select an option and watch and listen as animations for your setup's speakers are highlighted one by one.

As each highlighted speaker glows, you should hear a corresponding audio cue; if not, the specific speaker may be faulty or non-functional.

If your speaker system is non-functional, finding the best soundbar or speaker for your home media center could replace your faulty equipment and fix issues with your setup's audio.

What to Do if You Are Still Experiencing Audio Issues

If you have attempted to troubleshoot your audio issues with the above methods and are still experiencing issues, the issue may lie in your setup or TV settings.

If the Audio Setup animations were completely silent, it is more than likely that your HDMI cable itself is faulty. A quick and easy way to test whether your console isn't outputting audio or your TV or external display isn't is to plug in a headset to your Xbox controller. If the headset plays audio from your Xbox console, you know the console itself is still outputting audio correctly.

Improve Your Audio Experience on Xbox

Now that you know how to troubleshoot the most common issues you may experience with audio on your Xbox console, you may want to enhance your audio experience. Alternatively, if your audio equipment is the cause of your issues, you may want to replace or upgrade your hardware.

As well as replacement speakers and displays, finding the best headsets available for your Xbox console could Excellerate and fix any issues you have with audio on Xbox.

Killexams : Google launched additional support and troubleshooting for Consent Mode

Google is rolling out new features to deliver advertisers additional help with setting up and troubleshooting Consent Mode. A new certified partner program is also available with additional support with implementation and tech challenges.

About Consent Mode. Consent Mode allows advertisers to adjust how your Google tags behave based on the consent status of your users. It also enables Google to model for gaps in conversions. The Google tags will dynamically adapt, utilizing cookies for specified purposes when consent has been given by the user. using the consent signals, Google will apply conversion modeling to recover lost conversions due to consent changes.

Consent Mode status and diagnostics. Google has built new support and features to help advertisers set up Consent Mode correctly. The Google Tag Assistant troubleshooting guide covers possible cases and solutions if Consent Mode is not detected or consent is lower than expected.

Diagnostics can be directly accessed on the conversion summary or action settings page.

What Google says. “In coming months, you’ll be able to view troubleshooting alerts in your diagnostics tabs and see domain-level insights about your tagging and consent rate. You’ll also be able to download a list of URLs and access Google Tag Assistant’s consent debugging tools to help you fix issues with your setup.

Soon, we’ll be surfacing troubleshooting recommendations in the diagnostics tab. In the meantime, you can access the recommendations tab to ensure Consent Mode is properly set up and that you’re receiving the full benefits of conversion modeling” says Shirin Eghtesadi, Senior Product Manager, Privacy Centric Measurement, in the Google announcement today.

Activating Consent Mode. Advertisers can review eligibility requirements here. Google has also partnered with Consent Management Platforms (CMP) and is launching a new partner management platform with partners such as One Trust, Osano, Cookiebot, and more.

It should also be noted that in order to meet the thresholds, advertisers will need to have a presence in the European Economic Area (EEA) or the UK.

Get the daily newsletter search marketers rely on.

CMP partners. CMP partners are integrated with Consent Mode and Google Tag Manager, which help ensure proper implementation and address any technical issues. CMPs help manage cookie consent banners and direct the consent management process which begins when a user lands on your website and makes a consent choice on a CMP banner. The CMP then communicates that choice to the Google tag via Consent Mode, and the tag adjusts its behavior accordingly. 

Why we care. Most of us are fully aware that new regulations concerning privacy are at the forefront of our jobs as advertisers. Consent Mode ensures that websites protect the confidentiality and security of user data, while still allowing for accurate conversion and targeting data.

If you meet the requirements, check into partnering with a CMP to implement Consent Mode.
