My TV suddenly started displaying vertical colored lines across the entire screen, mostly white and black. There is no visible crack, impact mark, or external damage to the panel. The TV was working normally before the issue appeared.

TV powers on normally.

The backlight appears to be working.

The entire screen is covered with vertical lines and distorted colors.

No visible physical damage to the screen.

The issue appeared suddenly during normal use.

Power cycling the TV did not resolve the problem.

All cables and external devices have been checked and disconnected.

He said the area in which he lives is notorious for power surges. As the TV still has power and sound, I suspect the TCON board took a hit. I've been watching a lot of YouTube TV repair videos lately and several times I've seen people "work around" the issue by putting tape over some of the pinouts on the TCON's ribbon cable.

Before I try anything else I'm going to try power resetting the TV and also a factory reset. However, if neither of these steps solve the issue I'd like to try the tape method. Is there any way to definitively identify which pinouts are malfunctioning (if that is indeed where the fault lies)? More often than not, it seems like the techs just used trial and error.

Also, if anyone with this particular model has experienced the same issue and can provide some advice/insight as to what I can try to fix the issue that would be greatly appreciated!

Somebody threw away this TV and I had to pick it up

As I plugged it to the socket the screen turns on black, and after a few seconds turns off in loops.

After watching a few videos I tried a few things with no success:

1. Disconnecting the big semi white cable from the main board -the result is the screen turns on constantly on black, and there is a start sound. Then nothing happens, the screen stays on black.
2. If I cover half of the cable with a tape, connect it and turn the screen on I get the same result.
3. I tried using the "tape method" on the right side of the screen couple of times while slightly changing its location. Sometimes I got restarts in loops, and sometimes the start sound with black screen. Unfortunately no picture.
4. During the screen is on, I disconnected the cable connecting the power board (brown) to the main board (green)- the result is the screen's backlight stays on.

What can cause the problem, and how do I solve it?

I'm a biologist, so please be gentle with me 😊

I looked on the ribbon cable, and found out its model SFPCX495G-005 (see attached photo).

When I was looking for a replacement online, I found the exact model, yet the latter 5 digits are not the same.

Is it important?

Should I look for the exact numbers on the replacement cable?
