hello i have a xy monitor in a asteroids that started to twitch it just happens to the upper left of the screen over the plyer ones score any ideas please on what i should do....
hard to say without being there.. maybe one of the small signal transistors on your defleciton board.. or a bad gameboard.. have you isolated the problem to the monitor yet?
I have 4 asteroids machines. and a deluxe. I have seen different things cause this problem. Do you have another Pcb to test. Mine never were monitor issues. Pcb on one, and edge connector on the other.
