Hello!
So I was given a broken LED-TV with some unusual issues.
When I plug it in, it turns on and stays on, and does not respond at all.
The red standby light never comes on, it just switches on the backlight LED's and just stays that way.
The mainboard has a couple of green LED's that comes on and stays on, and I can't visually see any swollen or burnt components anywhere.
I replaced the T-con board to no awail and now I have started measuring voltages, but electronics on this level is above my knowledge.
The only clue I have is when I measure the voltages on the connector for the mainboard on the PSU-board, I am missing the 3,5V on both of the lower pins in the black connector in the pic below. I've tried applying 3,3V via an external power supply, but no change.
Any ideas?
