Someone please help me figure this out.. My toshiba tv keeps going through a demo mode in the contrast, color, etc area and also the buttons on the tv don't work.. All of them volume, channel change, etc, all they will do is change the TV1, Video 1, video 2, video 3, and then back to TV1.. It even does it by itself. You will be sitting there and the tv will just rotate through the settings..

This was an all of a sudden thing.. Went to work, came home and it was acting up.. The remote control won't even work the volume or turn the TV on or anything..

Any help would be appreciated.
