Here’s a good tip: if you get your TV wet, rush it to a TV repair professional! Immediately unplug the unit and don’t ever turn it on until it’s certified fixed by a tech.
Unfortunately, this is a hard lesson learned by the owner of a Sony LED LCD TV owner who probably thought there was no harm done when he/she got his unit watered down. Obviously, he was wrong as the video by norcal715 of Youtube clearly shows. Unit is a 40-inch Sony Bravia, relatively new (manufactured in 2010) and looked like it. It’s an LED model which means it uses LED backlighting technology which makes it thinner and lighter and more power efficient.
Well, the expensive problem came about when the unit got wet but owner just kept using it. In truth, water seeped down to LCD panel circuits at the bottom of the unit and stayed there while the unit was used. And so they found out the hard way that electricity, water and circuitry don’t really mix as the continued flow of electricity through wet circuits produced a process called electrolysis. This corroded or ate up the copper in the circuits which basically destroyed the TV.
As norcal715 suggested, this unit is headed for the scrappers. You could probably replace the LCD screen panel but that would be a very expensive route. One option is to try and look for a “for parts” unit with a good LCD screen display and circuits being sold on eBay and the likes, and get a good tech to install it for you. I guess that’s one option worth looking into if buying a new one is currently not an option. Or you could buy brand new from a cheaper brand.

I know this is not a discussion forum but cant you replace the board and tabs by gently lifting the scratch protector install new board with new tab and lay a new scratch screen, I am very much a green horn but i do not like accepting defeat!!
To fix this isn’t as difficult as you think. Find an old pcb board that you don’t use anymore, old vcr’s dvd players ect. Find a thin piece of track that is close to the same size as the ones that are broken on your tv. Use a scalpel blade to first remove the solder mask from the track on the old pcb. Gently cut the track to the appropriate length and peel it off from the old pcb with the scalpel. This may take a few practice runs to get it right . Next, scrape the back of the track to remove all the glue . This is the hardest part, I cant tell you how many pieces of track that jump away on me never to be found. Now go to the TV and scrape away 2x the track thickness of the solder mask on each side of the broken track. Using flux, add a small amount of solder to 1 side of the track. use alcohol to clean any old flux and solder mask debris. Add a small amount of flux again and with a pair of tweezers solder one end of your track to the tv. Gently clean area again. You may have to reposition the track , now is the time to do it. Always add flux and clean. Once you have it lined up , use the tweezers to hold down your track and solder the other side and clean once again.
