TV Turns Itself Off(Vizio M75-C1)
I saved this M75-C1 from someone’s trash. For the first three nights the TV worked great even though the guy told me there were issues. The next night the TV made a loud white noise/screech sound from the speaker on the left if you are facing the TV’s screen. The sound lasted a few seconds and would happen every few minutes. After that the TV turned itself off. I turned it back on and a few minutes later it turned itself off. After leaving it off for several days then trying it. It worked great for about 30min then it did the same thing. Which leads me to think it is a overheating problem.

Hard to see but I do not see any obvious damage on the power boards or the LED driver board. The main boar is the one under the metal. Let's take a look at that.
