Re: DYNEX DX55L-150A11 Randomly turns off

Probably not a lot of interest anymore as this is now an older TV, but I picked up one of the Insignia models because it was being discarded for this very reason.

The part # is MF72 5D20L, and an infrared scanner shows it at approx 170 degrees (F) when the TV is running. I suspected that this was overheating and shutting down the power until it cooled down, so I installed a 5v PC fan to keep it cool. Tapped into the 5v DC coming off of the white...
