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.
