Maybe one of the switches in your game is playing up. Could it be bouncing an input into the pascal board.
You could use disconnect the test and credit switches and then manually short the test switch and see what happens.

Just checked on Pinwiki and it looks like connectors J6 and J7 are the ones that connect to the switch matrix. you could try booting with those unplugged. I'm not exactly sure what will happen (will it boot or not) as J7 probably has more than just the switch matrix, but I don't have a full wiring diagram to check this.
If it boots then you can try connecting A1J6-3 to A1J6-8 momentarily this is the same as pushing the test switch (switch 00) if you get the menu up and no problem then you can be sure that the Pascal board is OK, but something in the wiring switches or diodes in your game is the problem. If you still have the problem with the switch matrix disconected, then I would suspect the pascal board.
