Personally, I'd rather have black borders on my TV after years of use than not be able to see the full picture until it shrunk itself to the right size.

But anyway, the TV in question is an Orion, but I'm not sure of the model number. And I don't have the booklet or box because it was a gift from a friend. There's a phone number on top though labeled "operating and installation help line". You think they would know how to fix it?
