Vizio M55-C2 - Will not turn on
M55-C2 Vizio TV, serial LWZASBAR variant.
Issue: Was playing a game and half the screen went to static. I turned off the tv to power cycle and was unable to turn it back on. The power light comes on, but nothing shows on the screen.
Have tried:
- Unplugging and plugging back in
- Holding power button for 15 seconds
- Using remote/power button to turn on the tv
- Unplugging for 30 seconds, while also holding the power button during the time
Which part of the TV should I look at replacing?
Questa è una buona domanda?

OK, so I had to figure it out myself. I replaced this part:
VIZIO M55-C2 MAIN BOARD 748.01208.0011 / 755.01201.0001 "SERIAL#: LWZASBAR"
After putting it in, everything worked just fine.

I can't believe this Joshua Spradlin -- our TV of the same model had exactly your symptoms last night. My wife and I joked that there may be a self destruct mechanism timed to go off 7 years just before each Black Friday. We got ours 7 years ago at just this time of year.
Aside from any conspiracies, I'm going to try the fix too, but I have essentially zero abilities with reading volts and circuitry. Does the job require any soldering or anything?
You happen to snap any pictures of your repair process?
Thanks in advance, and thanks for the timely help with your post!

paul waggoner replacing the boards is straight forward. Unplug the TV, remove the back cover, unplug the connectors from the board. Unscrew the board and replace with new board. No soldering and only requirements are regular hand tools like screwdriver etc. Nothing special. This video should help
