I even put dip switch on free play I cannot play my working game. Coin 1 & 2 and credit button doesn't register. When I put in Mat Mania coin 1 registers and controls work. Anyone know what I'm over looking?

Do the two games use the same pinout? If so, then you may have a board problem on Roc n Rope. I would try grounding the start pins on the edge connecter manually to verify whether it is a board issue or wiring issue.

Not exactly, which is what I said in his monitor repair thread when he asked the same question. The start buttons are reversed, the coin switches are reversed, and the controls are pinned completely differently. Only power, sound, and video seems to be exactly the same...

Did you notice this.....Only power, sound, and video seems to be exactly the same...
 
I think the cap I installed was wrong type. I was told 22 16v electrolytic condenser and it needs to be a tantalum condenser. Hope that fixes it.
 
Will check tonight. Thanks for suggestions. I replaced that to fix a sound issue but maybe it is a coin op issue I created.
