Is there a certain IC that is dedicated to the attract mode? The ship jitters/shakes when it's in the middle of the screen. Everything works great when playing normally. I did a Cap kit on the monitor and PCB's. While the PCB's were out I took out and cleaned all the IC legs that looked bad. I think I may still have a dirty contact but I don't want to go through each IC again if I don't have to.

Thanks.
 
Did you clean the inside surface on the legs? That's the side that makes contact with the single wipe sockets on the Galaga board.

Also, check for broken/cracked resistor packs if it has the flat type on there.

Yes, I cleaned both sides. I didn't clean the sockets other than blowing some air in them. Which resistor packs are the most prone to cause problems, all of them?

Thanks.
 
Go to my website and look for the Galaga Renew Kit instructions on the download page. There are pictures of those crappy kind in it.
