centipede slight graphics error and game wont start whos the repair guru

i got a centipede slight graphics error and game wont start whos the repair guru
is there some one here who knows the boards well?
originall would coin up but not go into game mode, test switch just shows white screen and letters that were misplaced on the game screen turn purple.
cleaned edge connectors and got it to start game, but couldnt move around, reseated trackball connector no change
game ran pretty fast way, no sound also.

not sure where to check all voltages, but i thought there wa supposed to be 24 + and -, 5 + and - , and 1 volt just for sound?
all i could find were some 24 and 30 only on polarity iirc not 100% sure

then took board out while i did same majoro clenaing all over the machine.
pulled off ever chip that was socketed and used fine sand paper to clean chip legs, etc, reseated.

didnt change much cept now when it goes into game made it immediatley game overs and goes back to attract screen.

What's the exact nature of the graphics problem?

Can you post a picture?

What happens if you put the game into test mode?

Are your voltages and connections okay?

ill try to get a picture today, its not noticeable at first. just a few extra letters around the words credits n what not, and i think in attract mode the centipede is like 2 parts wide and runs mostly down the middle real quick.

how do i put it in test mode? i can check my manual here shortly.
havent checked voltages, but i did reseat connections.
