My Magnavox TV cycles through channels and won't turn off

SOURCE: Buttons on TV or remote not working. Can only cycle through video input options.

It sounds as though the TVs in a demo mode. Has someone recently been over and was playing with the remote. If so go into the menu of the tV set and look for set up and demo mode. Turn off the demo mode. if this doesent help call i-866-427-3946 and talk to the customer service deptartment. Good Luck

Hi, If the AV button is not in your remote, then perhaps it is part of the Ch up/down buttons - meaning right after your last programmed Channel would be AV before the first program Channel. Although I have yet to come across such a case, I have worked on units/remotes that have this feature of the AV included in the channel memory. Good luck and kind regards.

If there is no input button on the tv itself to change the input then you will most likly need a remote. so you can get a universal remote and follow the instructions to adapt it to your set then you can use it to change the input. (you can get a universasl remote for like 10$) hope it helped

What source are you using? If cable, you should only be able to pickup channel 3 or 4 if you're using the box. If there is no antenna, that would be the only other answer if the set checks out...accordianman

if you want to use a single remote, try buying a learning remote
