I have a mitsubishi wd 77731 tv and the screen turned completely white with white vertical lines. what happen?

If your Mitsubishi WD-77731 TV screen has turned completely white with white vertical lines, it is possible that there may be a fault in the display panel or the video processing circuitry of the TV. This could be caused by a variety of issues, including a faulty LCD driver board, a loose or damaged video cable, or a problem with the TV's power supply.
Here are some troubleshooting steps you can try to determine the cause of the problem:

Check the video input: Ensure that the video input to the TV is working properly by connecting a different video source, such as a DVD player or game console, to the TV.
Check the video cables: Inspect the video cables that connect your video source to the TV for any damage or loose connections. If you find any damage, replace the cable.
Power cycle the TV: Turn off the TV and unplug it from the power outlet for 1-2 minutes. Then, plug the TV back in and turn it on to see if the issue persists.
Check for firmware updates: Check the Mitsubishi website to see if there are any available firmware updates for your TV. Updating the firmware may help to resolve any software-related issues.

If none of these steps resolve the issue, it is recommended that you contact a professional TV repair service to diagnose and fix the problem.

Hi Charlene,

please try with video input from any device,and i think you are using local antenna and it has gain problem or your tuner section of the tv is not working correctly.
if distroted pictures comes with video input signal it is video amp and processing unit problem.
you have to go for repair shop for fix that.
regards,
nuwan

White vertical lines across the screen. Why and what can be done? Thw white lines appear and stay all the way across the screen. They are about 1.5" inbetween each vertical line,

You have a failure in the vertical circuit. Service can run between $75 to $150 depending on your area.(In home repair will cost more) If set is older then 3 years and under 27" recommend replacing it.
