Hi there. My Vectrex has thrown a wobbly and I don't know what to do, I'm really frustrated. I have a white dot slightly off centre and up a little in the middle right of the screen. This just sits there. If I unplug the x,y,z inside then the dot jumps to the centre. Not sure if this means anything. I've checked the voltages from the board where the -5, gnd, 5 and 13 connector goes and they're all okay.
I just don't know what's wrong. Have tried re-siting all the chips, too. It was fine last night now it's doing this. Please if anyone knows how to help I would love to hear from you !
