Re: LG 50UH5530 Turns Off And Wont Turn On: diagnoses included

Gets worse, went to desolder the cap and found another burnt component. Guess it just a new mainboard, but right now everyone is out of stock and they want close to $90 for it. Maybe the hdmi shorted some components.

Thanks

Re: LG 50UH5530 Turns Off And Wont Turn On: diagnoses included

I may have found the issue. I broke out the cheap usb microscope and was scanning the main board and I think found out burnt out caps. These cap are right in front of the tcon connector.

Any idea what specs these caps are?...

Hoping for some help diagnosing the problem with my TV so I don't just throw parts at it or the land fill. Its an LG 50UH5530, that after being unplugged for a few hours it will turn on and stay on for about 15 seconds, before shutting off. After that, when pressing the power button the red led will blink but the TV will not turn on. I have read the folllowing post that discribe very similar symptoms and followed the steps documented.

STB pin on power board has 3.4v, always.
