problems with sony trinitron display, menu

Hi, New here, so forgive me if I don't use proper edicate.I bought a sony trinitron kv-27fs100 in 2002. It worked wonderful, so I talded my dad into buying one, oops. When we tried his it had two vertical bands of distorted colors about three inches wide down each side of the screen. He returned it and got another which worked fine. My tv started flipping through the video inputs by itself, but then seemed to heal itself. Recently my tv started to display distorted color bands down each side, then a while later "auto program" started poping up on the screen and then disapearing, over and over, while flipping through the video inputs. At first I the maybe the speakers were not shielded properly, but that didn,t make sense. I have a basic understanding of electronics. I am a extra class ham and I do a lot kits and built several tesla coils. No local repair guys will touch it. Any help would be greatly appreciated. Thanks, Mike, AB2DF.
