Hi guys... just got this Centipede. The game plays good but I'm having color issues. Background is blue instead of black and there are some vertical lines. I tried adjusting the pots but no change. Do you thi k I need to do a cap kit on the monitor board? Thanks. Mike

I would say you have a blue gun short, you can see the retrace lines in the blue. the reason it's probably not frying your corneas is because it needs to be rejuvenated. lol

caps won't fix this. what would be beneficial is either tell us what monitor model it is or post pictures of the whole chassis.
 
Monitor and board.

I think Randy Fromm gave me his blessing to share the gospel on how to fix it... it involves disconnecting the connections to the heater voltage traces at the neck socket, you create a secondary winding you wrap around the flyback core, and you connect that in place of the normal heater voltage circuit. the idea is you're removing the ground connection to the electron guns, that removes the short condition, you're basically creating your own AC voltage in its place. I'll see if I can conjure up my own pictures.

I knew it was going to be the 8-pin Philips tube when I saw it was a K7000x

Thank you. I'm willing to try whatever you think will solve the problem.
