TCL TV slowly goes black with sound
My TCL 75S431 slowly goes black after showing TCL logo and sometime stays on long enough to go through some setting. I can still hear sound when I press a button on my remote. I have posted some pictures as to how it looks before it goes black.

@jayrgooner how slowly does this happen? Does it go dark from one side to the other or equal across the whole screen? When the display is dark, darken the room and use a flashlight. Shine the light at an angle at the screen on different areas. Let us know if you can make out anything on the screen etc.

Sometimes it goes dark in a few seconds and other times a couple minutes. It usually gets dark from the outside in and other times from the inside out.

@jayrgooner check the backlights first. Going by the video, this appears to be an issue with the actual panel. Could be a driver board issue. To work on it you will have to start by removing the back panels and checking all the boards. then post some well focused pictures of all of those boards etc. with your Question. That way we can see what you see Adding images to an existing question

@oldturkey03 I too believe it is a panel board issue to as the backlight are on with the screen is black. When I press on the screen I can she light coming through. I will try to take it apart soon and update you.

@jayrgooner the only thing I can think off to do in that case, would be a Tape-off. Once we see what the inside of your TV looks like we can probably judge this a bit better.
