Vizio stuck on AMC,channel77,remote works/sound works and when you change channels its frozen on AMC but the audio is from the selection that you made.

If you are using an Antenna, Coaxial cable from the wall or a cable/satellite box connected to the TV with a coaxial cable, you will need to do the following steps:
1. Press the INPUT button on your VIZIO remote to view your current input source. Ensure that the TV input is the input that is selected.
2. If the TV input is not selected, press the INPUT button on the remote until the TV or DTV input option is selected.
3. Press the Menu button on your VIZIO remote and select CHANNELS.
4. Select the option that says FIND CHANNELS.
5. Once the scan is completed it will say DONE. Press the OK button on the remote once. This will go back to the channels menu and then you can press the EXIT button to leave the menu.
6. Use the VIZIO remote to change your channels

While the set is on, pull the power plug. Then hold and depress the power button in for about a minute. Then replug set and turn it back on. If that does not reset the tv then you do indeed have a serious issue with the set.

Have you tried unplugging the TV..holing the power button for 30 seconds, then plugging the TV back in? That resets the TV. Also, if you can get into the menu and select TV..then auto scan..that might work. I would try resetting the TV first.

One option for you is make sure you have tied ALL the codes, I know working with Comcast that there are codes that will do some features for a tv but not all. Check the other available codes.

Your TV is most likely locked to that station because it doesn't have any other channels programmed in.

In the menu for the TV, run a channel scan. This will take probably 30-45 minutes for most TVs and will program the available channels into the TV so that they become available.

I bought the same TV for my Mother last Christmas. She is having the very same problem. If you have come up with a solution, please let me know.

Simple Fix

I had the same problem, couldn't change the channels with the remote or on the side of the TV. This was for a Vizio 37"

Here is the fix:

1. Turn on TV

2. With remote, press the Menu Button

3. Go to Antenna Menu

4. Select Auto Search
Let it search, it could take several minutes. It may not finish to 100%, mine got stuck at 79% for 10 minutes. It's fine if that happens, go ahead and cancel.

5. It should be done, your remote will work perfect along with the TV channel buttons.
