Re: Vizio m420nv no audio, Eeprom?

It probably makes no difference, but what were you plugging in to the hdmi port? I was plugging in a desktop with an nvidia 650ti.

It's a little peculiar, because the 650ti recognizes the tv when the tv is set to any hdmi port that the 650ti is not plugged into, but the 650ti loses recognition as soon as the tv is set to the correct hdmi port. These seems to be true of all the ports.

I currently don't have any other hdmi devices to check with(I don't have the right cables, but they are in the mail). I checked the rgb port...

It seems like my picture went out sometime after I had tried to plug into the bad hdmi port....

Re: Vizio m420nv no audio, Eeprom?

Any update on this? Did you ever get it solved?

I ask because I also have a m420nv. Everything was working except the first hdmi slot. Then the second slot went out. Then all the slots went out. I'm not trying to hijack this thread, but I thought our issues could be related.

Then I bought a new cable to make sure it wasn't my cable, the screen went completely blank, no matter the source. Audio was still working from the antenna, though. I let it sit for many months, and recently turned it on, and now tv(video and audio)...
