I recently picked up a Polaroid TV for cheap. The owner had been using it as a computer monitor, and said that after a thunderstorm, it will now randomly turn itself off. I tested it on HDMI, and it will stay on a few minutes, then turn off. I also found that when trying to adjust the resolution from my computer via the HDMI port, it would turn the TV off immediately. When it turns off, there is a loud pop heard through the speakers. It will turn right back on without having to wait or unplug anything, then repeat the turn off after a few minutes.

All capacitors look good on both...

Hello, my name is Geoff, and I have come here for a little help with learning TV repair. I have been in the world of electronics for several years now, replacing components here and there on boards, but never on TVs. I Figured I would try my hand at it and picked up 2 TVs that are not working, or have a problem that appears to be board related.
