I just picked up a Joust. The monitor in it looks to be a TV picture tube. It is:
Rauland (Zenith) 19VMCP22
It looks decent, but the problem is the blue color. Red and green are nice and bright, but I just can't get blue to come through very well.
There are cutoff pots for each of RGB. But there are drive pots for only R & G. There are also pots for black level and screen brightness. No matter how I adjust them, blue just won't shine through very well.
First I verified it's not the tube by grounding the neckboard socket pin for blue - it correctly washes the screen out in nice bright blue.
I have a spare monitor with lots of screen burn sitting around, so I hooked it up to the game and blue looks great on it.
I replaced the blue CDT on the neckboard.
Any thoughts on what else could be the culprit?
Would a cap kit maybe do the trick? Problem is, I can't find a ready-made kit for this weird monitor. Is it unheard of to just manually ID all the caps and, well you know, assemble your own cap kit? Any caveats there?
Thanks!!
