Hi,


I buy a Steel Gunner PCB recently. PCB was working before sending (saw pics and video).
Package was good and nothing really noticeable. But...


At start, the self-test mode tells " 31 TIP ".
After, that ask "press start", and goes to a blue square and nothing.


I take times to clean the board. And reseated all the socketed IC’s. Made a visual inspection, and don't see anything specific.
I could try to get another Namco System 2 board to swap CPU board. But in this case i assume it's the video board that is wrong no?


Any advice from some of you?
The manual doesn’t show the self-test mode codes and match answers... Is there a way to know what is 31 TIP error?

Got a few tools but i'm basic, and not good in programmers etc...
