hey everyone,
if this is a monitor issue and not a board issue, please let me know and i'll repost it in the monitor section.
anyway,
i have a galaga that seems to be missing blue. you can't really see the wings on the enemies. any ideas?

Post a pic? Have you tried turning up your brightness or blue drive pot? Can you see blue in the starfield background? Is the score on top white, or is it tinted slightly orangish?
 
here's a couple of pics. i tried messing with the pots, no blue in the starfield.

damn it.

ok guys, not a monitor. unless...i randomly pulled a monitor out of a completely different game that had the exact same issue. so...anyone? i've already cleaned the board, pulled, cleaned, reseated the roms. and that monitor was a bitch to get in and out. grrrr.

Check video harness for continuity and the connector on the Galaga board - I've seen a few not make good contact.

yep try the harness. Clean it good. Check it at the board and at the monitor. May have to run a new wire:) good luck.
 
Check the PROMs on the bottom board (Video board)... There are 2 along the side of the board. Maybe you have a bad socket or prom.
