Hello everyone, first time posting here so I hope I'm doing everything right.
I just came into possession of a Sharp Aquos LC70LE755U. It was free for me, so with the stand and power cable I only have $30 in this. As such, I'm trying to repair it for cheap.
It works most of the time perfectly, except for an issue with what I think is the power supply. After anywhere from 10-30 minutes of usage, the screen backlight will flicker briefly, and the sound will completely stop working. The sound doesn't start working until I unplug the TV, wait a few seconds, and plug it back in. In addition, at lower brightnesses, the screen backlight flickers randomly.
From my research I've gleaned that both the backlight and speakers are hooked up directly to the power supply board, and now I'm wondering where to start looking as to repairing it. I'm also trying to get a board for cheap and just swap it in.
