I have an LG 50PG20 that won't power up. Yes its plugged in properly. The red standby light is on, when I try to turn it on the light blinks 3 times, once more and stays on blue for about 2 or 3 seconds then goes back to red.
I've hauled the back panel off as I have no warranty and I can't get a shop to look at it for two weeks but they figure it's the power supply board and will charge me around $400 plus labour. I see the same item on ebay for around $150 and it appears to be nothing more then a few screws and to unplug some wires.
So is there any way to confirm what the problem is for sure? I have no idea on the TV's history as I bought it broke without warranty. Thanks in advance.
