Re: Vizio M70-C3 ... Help with Diagnosis

Follow up.... You guys were right.
It was the Main Board. I ordered a used board online, popped it in an BINGO!
Thanks for the help from everyone here! I learned a lot along the way.

Different serial numbers...
That would have been too easy.

Re: Vizio M70-C3 ... Help with Diagnosis

Hypothetically.... If I found a mainboard (1P-0149J00-6012) on ebay, but it was pulled from a different tv model, is it still usable?

Edit:... So, not so hypothitically.... I found a board on ebay pulled from a VIZIO D58U-D3. Is there a reason it would not work?

Re: Vizio M70-C3 ... Help with Diagnosis

Thanks... I'll give that a try and report back.
Only thing that gives me pause is that the screen in the video is at least showing half the screen lit up. My screen is just completely dark. The half screen digital snow I got was only up for a minute and then the whole screen was dark after I shut down and restarted the TV.

Thanks for any help here!
I'm trying to narrow down which board may be the culprit for my non-functioning TV.
The symptoms:
I was watching (actually playing Elden Ring on) my VizioM70-C3 when half the screen went snowy (sort of a digital snow). I shut down and restarted and the screen was blank.
The indicator LED light in the bottom corner turns on and the audio fiber optic light in the back lights up but no screen.
I tried the "flashlight test" but am not seeing any images on the dark screen.
The internet is telling me that the caps go bad...

Heyo!
Trying to figure out how to fix my TV and this seems like the right place to be.
See you in the crappy Vizio threads!
