When I power up the board I get Coin SW on the monitor. Tried to put it in test mode and still just get Coin SW on screen. My other Arkanoid board works fine on this machine so I assume that it is a board problem. Any idea where the problem is on the board(which chip or area to check)?
 
Maybe you have a short keeping the coin switch circuit closed? (complete guess). If so and another board doesn't do it I'd guess the short would be on your board and not in your wiring. According to the manual, pin 8 on the parts side is for the coin switch. Maybe you can trace that circuit and see if any bad soldering might be shorting anything.

If you want to test the hypothesis of whether or not keeping the coin switch closed on boot would cause that, you could put your good board in, manually close the coin switch, and turn it on to see if you get the same message.
