Ok so i found out my power supply was faulty so i have switched to a new one. Voltage is good and the game pcb will power on and play blind.
Now my problem is the monitor. The first monitor i have only gives out green. Probably the green gun is shorted in the tube? I will have to take this to PNL for repair.
my second monitor tested fine when i tested it outside of the cab. But after i have mounted it, it will immediately blow out the chassis fuse and the cab fuse. I have checked the wiring and they all look good and there is a ground wore connecting the neck board to the metal frame. What would be the problem here? For your reference the cab fuse is a fast blow 3A 250V and the chassis fuse is a slow blow 1.5A 250V.
