sony kdl-32bx330 shorted out on frame?

[ValleyEcycling]

I have a Sony KDL-32bx330 that has just stopped working on me. It was manufactured in february 2012 and as far as I know has not had any power surges to note.

TV stopped working part way through a movie (didn't hear any popping noises or crackling) it just turned off, when i turned it back on half the display (left) was a vertical rainbow pattern that dissipated from the center back out to the left side facing of the display. The backlight would then shut off then turn itself back on after a few seconds but with no display (not even menu options are visible). Before the backlight turned off then back on again the SONY logo was visible for about 2 seconds.

I opened up the TV (out of warranty) to reseat the cable connections to the inverter board to ensure that wasn't the cause and I found that one of the bands connecting the panel to the board was burnt up! I have attached pictures below. Looking closer at it i have found that the metal piece holding the panel to the TV also had a lot of scorching and burn marks on it.

Has anybody else encountered a problem like this? And should I be contacting SONY about this issue? I mean looking at things it doesn't look like I have any repair options available anymore. Any help on the cause and/or solution to this would be greatly appreciated.

Is that board located at the bottom of the screen by chance?

Have you ever used liquid to clean the screen and maybe it ran into that area causing it to corrode and short out?

Thats what it looks like to me, water (or cleaning liquid) damage, that why I asked the location of the board.

Thanks for the replies so far. Yes that board is located flat along the bottom of the TV so i suppose any liquid put on the screen could feasibly drip down onto the board and cause the short. I have only ever used LCD screen cleaning foaming sprays to clean this with, but I can't promise that somebody else didn't use water or liquid to clean without me knowing it. The bezel seal was still intact however, took a fair bit of delicate prying to get it to let go of the panel.

Going to try cleaning the charred bits off today and will see what happens. I can see this short causing the issue of the rainbow display on screen, but would it cause the picture to go out as well after a few seconds or am i looking at a 2nd potential issue in the mainboard?
