unebonnevie Posted May 30, 2016 Share Posted May 30, 2016 Hi, My vectrex has a display problem -- really bright dot in the center and rays are drawn everywhere. I discharged the monitor properly and attempted to re-sit all the chips that are socketed. I checked all caps of the main board and the side board, and none is bulging. (Damned! In the process of taking the board out for cleaning, I broke the potentiometer that control the volume. Anyway, that's the least of my problem now.) Any idea what's wrong with the monitor or certain chips? Thanks! Quote Link to comment Share on other sites More sharing options...
Richard H. Posted May 30, 2016 Share Posted May 30, 2016 Looks like the brightness is turned up too far. Perhaps that pot is also broken. Quote Link to comment Share on other sites More sharing options...
FABombjoy Posted May 30, 2016 Share Posted May 30, 2016 Sometimes the x/y/z cable just needs to be reseated, or the connecting pins cleaned. Quote Link to comment Share on other sites More sharing options...

Yes, the brightness was turned up too far! It's OK now. I should have checked the obvious before doing surgery on my Vectrex. Well, I guess now I have a real problem to fix -- the volume potentiometer, which is tied to the power switch. Need to look of the ohm rating for the volume potentiometer and replace it. Thanks!
