What's your thoughts on this? Panel? Tcon?

It looks like panel issue but I need to look at the backside of the TV showing the boards.
Did any one spray cleaner on the screen when cleaning the screen?

If I disconnect the ribbon cable coming out of the tcon that feeds the right side of the screen, the left side comes on and works fine.

Then that is more likely to be screen problem, may be due to bad caps or bad COF.

I don't know the history of the Tv, I picked it up for cheap on marketplace. There doesn't appear to be any liquid damage.

It has tab bonding ton the bottom edge of the LCD panel, so if some one spray cleaning liquid on the screen, the liquid will drip down on to the tab bonding board are damage it. You need to get access to the tab bonding board and inspect the tab bonding board and check the resistance of the caps.

I don't think the boards got wet but I can see some oxidation on the chassis and tab on that side. Definitely had some liquid there.

Dammit. Has a hole burned in it. Add another to the scrap pile.

Too bad, it does look like that flex PCB got wet though.

I wonder how that hole happened. A manufacturing defect? What kind of voltage is on those?

Wonder if anyone has had any luck with the "cut tape" method on this model.

I've never heard of that. Do you have a link?

I just call it cut tape, some call it tape cut off method, example here, sometimes you have to play with the size of the tape: https://www.youtube.com/watch?v=j7vl7-vZEL8

That's interesting. I would think part of the screen wouldn't work if you did that.

Best I could get it to do. Guess I'll sell the boards on eBay.
