Hey everyone,

I've got a Vizio M420nv TV that when I turned it on, showed the VIZIO logo and subsequent NO SIGNAL display in reverse (a mirrored image). Even the menu system was mirrored. I reset the memory (factory reset) as well as unplugged the tv, pressed power button, plugged back in the power and turned it on.

So far my troubleshooting has gotten me nowhere. The warranty is out. I've read that it could be a Tuner Signal Board issue as well as a mainboard issue.

Does anyone have any experience or can help me narrow down the fault to a specific part of the hardware?

Thanks in advance.
