1. Mitsubishi VS-4571 projection tv. Likely flyback transformer blown but would like to have diagnostic info for testing before replacing 2. GE 27" picture in picture from about 5 years ago. Picture cannot be resized - is too large for screen. Screen size adjustments set by system in ROM onboard, but tech said there are two capacitor/diode pairs which could be issue. Need schematic to get part #s for the two for replacement. Will post model # when I get home. Thanks, Rob
