Can't change channel using the remote or buttons on tv


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.

Remote control does not work for my plasma tv


I also had this same problem. Both the original remote and my universal remote failed to give any response on the TV. Normally the green light flashes when it receives a command from the remote. Called LG Support and they made me an appointment with a local repair company for 3 days later. This seemed pretty quick compared to other companies repair times I'd read about. However next day the repair company called to say it would be 5 more days before they could get a Tech to my location (downtown ATL). 8 days was a long time to wait but once tech arrived he diagnosed it to a bad board and simply went to his truck and swapped it out with mine under factory warranty. Everything has been fine since.
