Make sure to check if your power supply is working, and to be sure that you have 5 Volts on the main board.
Make sure to clean the connection junction between the boards along with the interconnection board.
I'm curious about the symptoms about what is happening. Do you have anything on screen (Garbage/Artifacts)? Is there any sound being played?
Pole position is quite notorious for having the most problems..
I have two working pole positions and some spare working boards.
I had a few in the past and I managed to fix them. These 2 machines have been sitting 20-25 years and the corrosion is horrendous. I pulled a chip and legs broke off. As I cleaned more broke off.
The other problem is j cant swap parts because one has the namco PCB and the other has the atari.
I started on the namco cab and followed the startech journal and installed a switcher. So my power is good. K hear the sou.d amp kick on but no garbage. Just blue screen.
I'm going to start on the other cab next but it's in worse condition inside because it was stored without a back door. So its nasty. I need to put a new bottom in it. The pcb has really bad acid damage.
Not being able to swap parts is a kicker. I'll keep lugging away.
Both were converted to pp2 btw. I have 1 spare atari pp1 pcb but its parts and no interconnect pcb.
I would be happy if j found a spare namco pcb. Even if it's just parts.
