55SJ8500 won't turn on. red blinking light
I have a 55 in LG TV. Similar to other threads related to screen not powering and on red light blinking 3 times. After that the red light disappears for about 10 min and then returns. Any attempt to turn back on yields the same result…light blinks 3 times then goes away.
I’m relatively inexperienced when it comes to this type of stuff but willing to mess with things to try a fix. I’ve seen several posts concerning capacitors replacements but also some other posts indicating the issue could be coming from multiple sources.
Where would you recommend problem shooting first?
I got the back off. Here are the pics of the two boards.
after taking the back off I plugged unit back in. Screen came on but was not responsive. Unplugged and plugged back in. Now red light. I do have a green light flashing on the power board.
