I took my old Goldstar 19" apart last night to see if I can adjust the overscan on it. I saw these 2 resistor dials on the board figuring they might be the ones. I didn't get a chance to see if it made any difference on the screen because my screw driver slipped and blew a fuse. I know it's a dangerous place to be working. But I really HATE excessive OVERSCAN and would like to adjust it to 1%. The TV I wanna do this to is our main TV in the living room, which is a POS Magnavox 1989 25 inch TV. This TV REALLY sucks. I know. And I wanna decrease my overscan on it because some text at the bottom and the top are cut off. OVERSCAN!!!
