This is more of a provider problem. Report the signal problems to the service you subscribe to for tv.

Not a solution but EXACTLY the same TV and same problem. Have tried: Unplug for 2 hours, press CH+ and CH- simultaneous, then press/release power, then release CH+ and CH-. Nothing..

Most sets with digital tuners do this. The best thing to do is manually save them into memory, unless they are the same numbers, this would keep the channels tuned until you go back to them

I had the same problem. I also use rabbit ear antenna , no cable or satellite. I was watching ch. 33.1 and the tv turned off by itself. The remote wouldn't work. The power on/off buttons on the side of the tv wouldn't work. I had to un-plug the power cord to turn the tv off. The tv forze on ch. 33.1 when I turned it back on.

I called Vizio, they told me they received hundreds of complaints from people in Texas complain g about these problems.

I was told to un-plug the antenna cable and re-plug it. I did this plus I re-scanned all channels. The problem has been solved, the channel (33.1) no longer freezes and the tv doesn't turn off by itself.

Hope this helps.

could it be Ch 9's digital signal is not broadcasting right? what is your refresh rate on your tv? 60 or 120hz? if its 120hz, then its more then likely the digital broadcast, if its 60hz I think its your tv can't keep up with their signal that may be at 120hz. Make since??

Do a full channel scan again. It should solve that problem.

The problem is a defective main board, the EEPROM on the board is defective.
