SanyOur house was struck by lightening and now I can only get sound from my TV when connected by the coaxial cable or the RCA (red/white/yellow) cables. If I connect the TV using the componant (red/blue/green) jacks then I get full sound and picture so I know the TV picture does work. Trouble is I do not have an extra cable box or VCR to connect the TV by componant cable.

I plugged this TV into a new cable box (digital signal, not HD), and the picture now does not fill the screen. Previously, I had another TV (different brand, same tyoe and age) plugged into the same cable box, and never had a problem. Is there a way a) to adjust the picture to fill the screen without using the zoom feature, or b) if not, is there a way to make the zoom feature permanent so I don't have to activate it every time I turn on the TV?
