Well, to eliminate a software issue, turn off the game, pull the RAM chip from the main board (the IC under the 2 labeled EPROMs) and then reinstall it. Turn on the game. See if that clears it up.
If not, then it is a board problem.
Check the ICs for switch row and switch column with a logic probe, otherwise send board out for repair.
