Ok guys I have this tv stripped down to the led backlight. It appears someone had a Alcoholic drink spill all over this poor tv to where it went down the screen, onto the now very sticky driver boards. I've cleaned everything to the best of my ability. It seems what it is doing is just turning on and off over and over. When the screen flashes on for a second there is one small vertical line in the middle of the panel. Can you all tell me if this thing is trashed or if its worth fixing. When I plug in power to the psu and no mainboard attached nothing happens. When I plug in mainboard it starts power cycling forever. All the leds do flash when it does power cycle so the leds are all good. Now I am just wondering if it's the mainboard, psu, tcon or possibly the panel has permanent damage to the delicate ribbon connector from the liquid damage hence the vertical line? My money is on the mainboard personally but who knows can ya'll help me- thanks I can provide pictures of anything. The liquid appears to have run down the screen so all the main boards are all fine and undamaged except the driver boards look ok but they are fairly sticky.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: LG-49LB5550-UY Water Damage
If you don't get any image while it's flashing, it doesn't make sense to fix backlight.
But here is an example of me fixing water damage:

Re: LG-49LB5550-UY Water Damage
Ya unfortunately it looks like this screen sustained some physical damage to the screen as well. So I'm going to be parting this one out on e-bay or something I guess. Thanks for your help man. I cleaned all the ribbons good with ipa but still line so not worth fixing ya know.
