I have a LG 47LK520 that was hit by a lightning storm and have been trying to repair it. When plugged in, the red light glows steady and when the power button is pressed the light pulses red every couple of seconds.
Initially I bought a replacement power board thinking that would fix it but doing so didn't change anything. After some research I found out that the capacitors are often the problem however the capacitors on both my replacement board and the original board look fine. No bulges, no leaks, no busted tops.
So after some more research I came across this link:http://blog.workingsi.com/2013/06/li...lw5700-tv.html
and

which had me pretty convinced that it was the main board.
So I purchased a new main board form ebay, installed it and still no change, the TV was still going to the blinking red light mode. (I ended up returning the replacement mainboard I bought because, while it was the same model number, the heat sink didn't fit in the cover of my TV for some reason.)
So, I'm kinda stuck on what to do next. I was thinking I should by another mainboard as the one I ordered on ebay may have been faulty. I'd really appreaciate any help I can get.
