Hello,
I bought a Vectrex with a stated problem: a white dot and no sound. When it arrived, I replaced the 2764 EPROM, the two 2114 RAMs, and the 6522 PIA.
The sound came back, and the white dot is no longer just a fixed dot, which is visible in the video.
But I got to this point and I can't find the culprit, please help and advise.
Thanks!
