Re: Vizio M470NV Tuning issue
Yep, tried all that. Also disconnected the antenna, scanned, then reconnected and scanned again. When I tune to one of the faulty channels, the show comes up, then freezes on the scene. Then when switching to the next channel, all channels are blank. Has to be the tuner/main board.
Not sure it is worth the cost, but only paid $75 for the set, has a greaat picture and I tend to like to fix things rather than throw them out.

Re: Vizio M470NV Tuning issue
Not yet. I just picked up the TV second hand. I will try to get an update to the firmware. As you said, just odd that selecting a few particular channels would result in all the channels unaccessable.
Basically, I can be on a working channel, select the next channel which seem to try to sync, then nothing. When I switch back to the good channel, I eventually get a message "Channel Not Available". Power cycle and that channel will come back up.Leave a comment:

Vizio M470NV Tuning issue
When I run the auto-tune, the channel list shows a few channels with no information. Scanning through the channles works fine until selecting one of these channels. Then none of the channels will display until power is cycled. I am thinking a tuner issue which appears to be on the main board. -
