The TV processor could have some garbage in it do to a small power surge and if you leave your TV unplug for 40MIN., then that will reset it bad to normal, and if tuner still looks snowy and not getting channels, then the tuner, or main TV module needs replaced.

Is the HDMI port 2 work? Try to turn it off and turn it back on. If it is still not working then the HDMI ports have gone bad. You will need to replace the main board.

I had the same problem with my 42" vizio. Was working fine for about a year and a half, then a month after all stations went digital, I couldn't see any digital channels and it wouldn't scan for digital signals
This is a strange go around, but it worked for me. . Tried unplugging, pushing power button for two minutes... did everything the forums suggest, with no resolve. But, here's what DID work for me. Trust me, it sounds strange, but it continues to work (and, yes... it's not a permanent fix... the channels still go out once in a while, but I can always get them back now)
Use your Vizio remote control. Turn your TV on. Press the "input" button until you get to "RGB", which is what you would connect a computer to. Make sure no computer is connected, or it's at least off if it is connected. When you get to RGB, you'll see a message that says "No Signal". After about 5 seconds, the TV will enter a sleep mode and seem as if it has turned off (orange Vizio logo). Once it completes it's little sleep cycle and "clicks" off, wait a few seconds and hit the input button again. It'll go to the next menu item. Keep clicking input until you're back on "TV", and VUALA! The channels are back!
I accidentally figured this out when trying to troubleshoot, but I'm glad I did. Didn't want to dishout $250 to get it fixed. Let us know if it works for you too!

No.You might not have a reliable service provider or you might just be in a area in which t.v. signals are hard and or impossilbe to recive.You might also have the cable box,or just cables,mixed up.Hope it helped.
