The pink or purple image is caused by the HDMI connection from the cable box to the TV. If the problem persists, there might be a problem with the HDMI cable. Please try another HDMI cable. The green image is caused by your video source. If the problem persists, try another input on the cable box.
Pink screen troubles are typically caused by HDMI connection issues. It's possible that the HDMI connector isn't properly put into the HDMI port on the TV (or video source component). A faulty HDMI input port on the TV or video source component, or a faulty HDMI cable, might also be to blame. If you're using a digital AV receiver as your video source, make sure it's set up correctly with its HDMI terminal connected to the correct HDMI port on your TV.
If you're still getting a pink screen after checking all the above possibilities, then there could be a problem with your TV's backlight control panel. This controls how the whole screen is illuminated, including colors. If the backlight control panel isn't working properly, only the center of the screen will be lit up in color, leading to a pink screen appearance. This problem can also occur if someone has been fiddling with the RGB values inside the television's internal software system (FCC ID 058:0000) in an attempt to fix other problems they may be having with the picture quality.
The good news is that this is a simple problem to fix. All you need is a multimeter and some knowledge about electronics. First, use the continuity test function to make sure that none of the wires in the HDMI cable are broken. Next, measure the voltage between any two pins on the HDMI connector. There should be at least 3 volts difference between these pins.
If the screen remains pink, the issue is most likely a faulty video adapter or a faulty driver.
The most common cause of a green screen on a TV is a loose or broken cable connection from or to a media component. Check that the cords that connect your SAT box, cable box, DVD player, ROKU player, and other devices to your TV are secure and not damaged.
If the screen remains pink, the issue is most likely a faulty video adapter or a faulty driver. Video adapters fail for many reasons, including bad capacitors, which will cause black screens to show up when you turn on your computer. Drivers can also fail, particularly heat-sensitive ones such as audio drivers or display drivers. If you believe that this is the case, take out the graphics card and see if there is any difference in behavior. If not, then it's probably the video adapter.
If you are able to view other screens on your computer during boot, but not the main one, this means that there is an issue with your boot configuration file. To fix this, start by checking whether or not there are any values in the BOOT Configuration Option section of your BCD (boot configuration data) file that have been changed by a previous repair attempt. If so, delete these values and restart your computer into Windows.
If this doesn't work, try reinstalling Windows. This problem may be related to a hardware malfunction. If you still cannot get your computer to boot properly after trying these steps, you should consider getting it fixed by a professional.
If the screen remains pink, you may have a defective video adapter. Depending on the hardware design of your computer, repairing a damaged video adapter may entail replacing an add-on card or replacing the motherboard completely. If you have another video adapter connected to your system, try disconnecting it and see if that resolves the problem.
If the screen returns to normal after a few minutes or hours, then the problem may be with your computer's power supply unit (PSU). Computer screens use electricity to display images and videos; therefore, they require energy to work properly. The more advanced the screen, the more energy it uses. For example, a laptop screen requires more power than an older television because it is more sophisticated and contains many more pixels. As such, a laptop screen will usually display a warning message before shutting down due to low battery power.
If you observe other symptoms related to your PSU, for example, if it makes unusual noises or smells like burning plastic, then this is something that should be taken care of by a technician as soon as possible.
Check the menu screen to check if the same problem exists. If the problem persists, the TV may be defective. For more troubleshooting, see the article on weird colors and other screen difficulties. It is not a bug if the menu screen does not have the same problem. You may customize the image parameters to your liking. For example, you can adjust the color temperature or select from a wide range of picture modes.
If you still cannot fix the problem, then contact the manufacturer for assistance.
How to Troubleshoot a Pink Screen on a Computer
Inside the TV, there is most likely a loose or filthy ribbon cable. A faulty ribbon cable might also result in a green screen on an LCD HDTV. The video drive chip in other types of TVs may be defective. A malfunctioning video drive chip might result in a red, green, or blue (RGB) problem. This would also affect an LED TV.
In general, a green screen on an LCD HDTV means that there is a problem with the panel itself. It might be damaged by UV light from the sun or else contain impurities that display as green color when illuminated. Such panels must be replaced under warranty. Out-of-warranty repairs are possible but might not be covered by insurance. In this case, an expert should be consulted to determine what caused the problem.
A green screen on an LED TV usually means that there is a defect in the manufacturing process. LEDs are tiny chips that require careful handling during production. If done improperly, they could break off inside the TV and cause damage to internal components. Under warranty, an expert will be able to diagnose and fix this type of problem.
As for non-warranty repairs, these TVs are made of plastic and therefore susceptible to damage from heat, moisture, and mechanical stress. Attempting such repairs yourself without proper training and equipment can lead to further problems or even damage the device completely. Only use approved accessories when working on your LED TV.
