Hi Everyone, New to the forum and Vectrex. I picked up a non-working unit and am trying to bring it back to life. Symptoms are as follows: Hums when turned on (transformer reads about 10V AC) Speaker crackles when volume is adjusted, but no sound VERY faint dot in center of screen when brightness turned all the way up Filament briefly lights when turning on cold (< 1 sec). No light at all when warm start Cable from power board to logic board sending +/-5V and -13V (checked from the logic board, not the connector) All electrolytic caps just replaced (no change in symptoms, as I tested it before) - most of the caps were fine, a couple had high ESR, a couple were out by >20% Filament appears to be getting about 7.5V AV Input to flyback looks like it is getting +/- 11V (should be 9?) Outputs of flyback about half their expected voltages Flyback has no dead shorts (all between 0.5-2.0 Ohms) I have some experience recapping and repairing 80's oscilloscopes, so I'd say I have intermediate skills. Any advice is greatly appreciated! Thanks, Stefan
