Hy everyone,
My living room TV is gone, no image and just sound, complete black screen.
It is only 2months out of warranty and I've toke it to LG, it is a very recent unit and the warranty has expired just 2 months ago, diagnostic: mainboard problem and must be swapped, the price is more then the TV it self so is not worth it.
I've explored a few 2nd hand units with the broken screen (the most common problem on LCD panels) and I've found a 49UM7100PLB, the mainboard is exactly the same. I've bought it, made the swap but nothing on the screen.
Is there any firmware or EEPROM to be programmed before this board can be fitted in my unit? The hardware seems exactly the same, same part-number so I'm a bit confused. By the way, I checked the backlit LED's, all are good, they are all on. The P/N of the board is EAX68253604 (1.0).
Appreciate your experienced inputs!
