If you have the newer, dark green revision Galaga or Bosconian boardsets, the ones with the main CPU on the right side of the board and the other 2 CPUs down the left side of the board then check the capacitors on it!

I have 2 of those boardsets here to repair and both of them had leaking axial electrolytic caps on them. One CPU board had a trace eaten up because of it and both boardsets had damage to the cap's solder pads on the top side of the board.

You need to replace the caps on those boards! They are:
  • 3 220uf@16v
  • 1 100uf@16v
  • 1 22uf@16v
  • 2 10uf@16v

Look at the legs on the caps. They should look like shiny or grey metal. They should not look green or fuzzy! Both boards had dark green legs on the + side and lighter green on the - side of each cap.

Also, don't forget, I have another thread somewhere about the Namco Classics Vol1 and Vol2 boardsets having the same cap problem - except those are surface mount. If you have those boards check 'em too!

I have them same boards and will look at them today.

Thanks for the heads up on this issue.
