Did you try resetting the settings of the TV using the remote to make sure that this is not just a settings problem on it...

Try 2 things:
1. If you have a cable box with the yellow/white/red outputs, use a compatible cord to run the 3 to another input on your TV (ie input 1 vs cable). and/or
2. Do a Factory reset. Hold the "menu" button on your TV then on your remote hit "menu" then "8" then "select" and go to "factory reset". You may have to unplug the TV as it may freeze on "factory reset". Replug it then try it out.

Hope it works.
