I recently acquired an almost working Ms. Pacman. After fixing the monitor, I have discovered a second problem. "Up" on the joystick does not work.
I have checked all of the obvious. There is a solid solder connection with the white/red wire and the ground wire on the leaf switch. When I jump the two together, there is still no up movement. I tried jumping to a different ground point. I have also tested the white/red wire from the switch all the way back to the harness. I am hoping there is a simple solution because I am lost when it comes to troubleshooting PCB's.
Thanks in advance for any and all help.
