A common problem with TVs is the yellow screen issue, which affects how you see things. This problem shows up as a yellow tint on the screen, making colours look faded and dull. Various things can cause this problem, like a broken backlight, wrong colour settings, or a damaged LCD panel.
This issue isn't specific to certain TV brands or models—it can happen to any TV, though some brands like Samsung, LG, and Sony might be more prone to it. If you notice the yellow screen problem on your TV, you can try a few simple steps to fix it.
Adjust the colour settings, reset the white balance, or update your graphics card driver. If these tricks don't work, it's best to contact the manufacturer or a professional repair service for help.
Here's a simplified guide on accessing and adjusting colour settings on your TV:
- Turn on your TV and press the Menu button on your remote control.
- Go to the Picture or Display settings menu.
- Look for options like Color, Brightness, Contrast, and Sharpness. Adjust these settings to enhance colour balance and contrast.
- If you're dealing with the yellow screen issue, try resetting the colour balance and contrast to default values by selecting Reset or Default in the settings menu.
If the problem persists:
- Consider calibrating your TV by adjusting colour production to match standard patterns.
- Manually calibrate your TV by tweaking colour settings with a test pattern.
- Alternatively, use a calibration disc or seek professional services for a more precise adjustment.
Here's a simplified guide on checking and securing cable connections to your TV:
- Turn off your TV and unplug it.
- Examine all cables connected to your TV, like HDMI, Component, and Composite cables. Check for loose or damaged cables and ensure they're firmly plugged into the correct ports.
- Replace loose or damaged cables to avoid colour distortion and picture quality issues.
- Plug your TV back in and turn it on.
Cable types like HDMI, Component, or Composite connect devices (gaming consoles or DVD players) to your TV.
HDMI cables are the most common, transmitting audio and video for the best picture quality.
Component cables transmit video signals only but still offer good picture quality.
Composite, less common cables only transmit video signals and provide lower picture quality than HDMI or component cables.
Addressing external lighting, sunlight exposure, and room ambience affecting your TV screen colour:
Adjust Brightness and Contrast
- If the room is too bright, increase the TV screen brightness.
- For dark rooms, lower brightness to ease eye strain.
- Adjusting contrast enhances colour balance and picture clarity.
Use Curtains or Blinds
- Block sunlight with curtains or blinds to prevent glare.
- Reducing light entering the room helps preserve TV screen quality.
Utilize Ambient Lighting
- Create a soft glow in the room with lamps or light sources.
- This minimizes the contrast between the TV screen and the surroundings, reducing eye strain.
Calibrate Your TV
- Improve colour accuracy and balance through TV calibration.
- Use a calibration disc or professional service for precise adjustments.
Checking and installing software or firmware updates for your TV:
Turn On Your TV
Press the Menu button on your remote control.
Navigate to Settings or Support
Go to the Settings or Support menu.
Find Update Option
Look for options like Software Update, Firmware Update, or System Update.
Select Update Option
If there's an update, follow the on-screen instructions to download and install it. This may take a few minutes.
After the update, your TV will restart automatically.
Keeping your TV's software up-to-date is crucial to avoid display issues. The update process might differ based on your TV's brand and model. Still, detailed instructions are usually provided on the manufacturer's website or in the user manual.
White or Black Dots
Issue: DLP chip fault, causing fixed white or black dots on the screen.
Cause: Mirrors in the chip stuck in the on or off position.
Issue: Distorted or discoloured colours on the screen.
Cause: The faulty colour wheel is responsible for producing colours.
Flickering or Dimming Screen

Keep in Mind
If you notice any of these issues, it's advisable to seek professional repair services. Trying to fix internal hardware problems yourself can be risky and might damage your TV further.
External devices, like set-top boxes, streaming gadgets, or gaming consoles, can impact your screen's colour in various ways. If these devices aren't set up properly, they might make the colours on your screen look faded or messed up. Likewise, if the device isn't compatible with your TV, it can make the colours seem too intense or dull.
To Troubleshoot these issues:
Check Device Settings
- Ensure the connected device is configured correctly.
- Adjust colour settings following the device manual or manufacturer's instructions.
Inspect Cable Connections
- Verify cables are securely plugged in, with no damage.
- Loose or damaged cables can distort colours and affect picture quality.
Update Device Firmware
- Keep device firmware up-to-date to avoid display issues.
- Refer to the device manual or manufacturer's website for firmware update instructions.
Try a Different Device
- If issues persist, connect a different device to your TV.
- If colours are normal with the new device, the problem likely lies with the original device.
A factory reset or tweaking service menu settings can help troubleshoot TV issues. However, be cautious, as accessing the service menu can be risky and may harm your TV if not done correctly.
To factory reset your TV:
- Turn on your TV and press the Menu button on your remote.
- Go to the Settings or Support menu.
- Look for options like Factory Reset, Reset All Settings, or System Reset, and select it.
- If prompted, enter the PIN or password (usually 0000 or 1234).
- Follow the on-screen instructions to confirm the reset; it might take a few minutes.
- Your TV will restart automatically after the reset.
For adjusting service menu settings, access varies by brand and model. Typically, it involves pressing specific buttons on your remote. Remember, accessing the service menu can be risky, potentially causing permanent damage. If you need more clarification, seek professional help.
