The view finder and auto focus are two different things. The camera can work and the view finder doesn't. The view finder circuit board is probably burned out or has a some bad components. If you are good at electronic circuits you could take the circuit board out yourself and try to trouble shoot it. But your chance of success is nil.
RCA no longer carries this camera on their website so help is not available unless you were to take it to a repair shop and then they may not be able to get the parts. Or you may get lucky and they can fix it. You should try that first. At least you'll know what it will cost to fix it.
This camera is sold on EBAY, you might be able to get one cheap enough for spare parts.
My suggestion: I thinks its time for a new camera. Unless of course you still love VHS.
