Title: Simpsons PCB controller issue
Post by: bluemanop on March 07, 2005, 11:10:35 pm

Has anyone ever had a problem with their Simpson's board where the left and right function on all 4 controllers don't want to function?

I have gone into the diagnostic and it seems like player 2 & 3 on the left and right (0 & 1) screen seems to jitter or flicker on and off repeatedly.

Is this just a matter of replacing the stand up ICs in S39 and S40 (page 9 of the manual, upper left)? These parts seem to be pretty standard on these Konami boards.

Did you check for shorts?

Yup, it looks to be a very clean board and actually looks as good as new. No dust or any foriegn objects noted on the board.

No, I meant with your joystick and button switches and wiring...

Yup, I am able to plug up two other Konami 4 player jamma boards to this rig without any issues with controller problems.
