I purchased this board and it has some glitches. Has split screen in attract. During game play only the upper scores and lower portion are split. I have reset the chips adjusted the 5 vdc but did not make a difference. Any thoughts suggestions? Thanks

These CPS games have 3 boards, the bottom is the A board, the middle is the B and the top is the C. Usually, when things go wrong, the culprit is the A board, hence the suggestion to test the B/C board you have with a known working A board. That will better pinpoint where the problem lies with your PCB...
 
Probelm can lie in the CPS-A-01 ASIC on A-BOARD or the CPS-B-XX ASIC on C-BOARD.Try to swap two good boards.
