I purchased a joblot of old arcade machines yesterday, one of them was the f14 pinball machine.
It powers up, beeps... and the led display on the cpu board flashes between 0 and 7 really quick, if i press cpu reset, or play with the buttons attatched to the coin mech, it will reboot and work fine.. (apart from the display... only 1 works)

I checked the 5v line.. which is ..4.94V.. a little low but not enough for it to trip like this is it?

I measured the +100v and -100v lines going from psu to the display board.. they both appear to be present so the fault with the display.. i wonder if its related to the fail on power up?

Does anyone have any idea?
once i reset it, the game plays 100% bar the display..

my first pinball machine so im learning as i go ...
 
Hi You will probably get a lot more replies if you post this in the pinball repair section. Good luck with your game. It's a fun machine!
