First post here: There are already a handful of threads on this TV w/ similar symptoms, but I've worked on mine to a point where I've got strange symptoms I haven't seen anywhere else.
VIZIO M60-C3
Initially, I had no picture, backlight or audio. Power LED on bottom and red audio LED on main board lights up and goes away.
PS_ON: 0V
T CON_ON: 0V
12V T CON: 0V
etc.
Took out the main board and cooked it in the oven for a little. Reinserted and found that the backlight would turn on and I got the bootup "V"...but then it would shut off again. Every 30s or so, it would kick back on and do the same thing.
What I found from the readings then, was over double voltage for everything!
12V TCON is 26.3V
12V-AU is 28.8
PC_ON is 10.4
What's the deal?
Anything else I should check for? Is this a Power Supply issue or still my main board? Any help is appreciated.
