Question about Sony FD Trinitron WEGA KV-20FS120 20" TV
I think what your asking is for an on screen service menu?? That wont fix your problem. It sounds like you have a vertical height problem where the screen doesnt fill the entire screen with the Picture. The adjustments wont go out like that for no reason and all by them selfs. The vertical sweep IC went bad and is going to have to be replaced. This is not a job for the end user. You should call an experienced tech to assist you with this repair. Good Luck
