Why won't my TV turn back on? LG50LN5200
Last night my TV abruptly turned off and wouldn't turn back on. There is a static red light at the bottom of the tv showing power when turned off but plugged in. After the tv turned off, this light did not come on although it was still plugged in. When I unplugged and replugged the tv in, I noticed that the light was now on but very dim. The tv still would not turn on. I left it unplugged overnight. This morning the tv turned on and worked for a couple of hours until repeating the issue. I was informed that this is very likely a power board issue. I'm trying to get a confirmation and whether just a component needs to be replaced or the entire thing. Attached are pictures of the power board.
