I bought a donkey kong that when powered up the screen is all dark maroon in color. The game plays fine except for the god awful speaker hum. The screen background is not black at all, just maroon. There is also a black right side vertical line on the right edge of the picture. I think it is foldover. Here is the weird thing. After the monitor warms up for 15 minutes, the background slowly goes to black with just a tinge of maroon. Almost normal but not quite. Black right egde foldover is still there.
I figured I just need to cap it. I tore out the chassis, and everything is very dusty except for all the bright and shiney caps! It looks like it must of been re-capped sometime recently. They did not do the audio board caps hence the humm.
Question is should I pull out all these nice looking caps with like new solderjoints, and recap it, or is this just some sort of monitor adjustment. Should I recap only the audio board, and reinstall, and make some sort of monitor or b+ adjustment?
Hate to replace shiney new looking caps for no reason. Now that it is out, maybe I should recap?
Does anyone have a good link to a cap map for the 20ez? Mine stinks. Thanks,
Rick
