I originally had my TV connected without a cable box, then I moved it into a different room that had a cable box, and now it's back to the room without a cable box. But now it's not memorizing channels, whereas it was working completely fine before. Now, every time I turn off and turn on the TV, I have to go through scanning for channels again... every single time.
Is there anything that I can do to fix this? Does having it hooked up to a cable box temporarily have anything to do with causing this problem?
