I have a Zookeeper that upon coin up will not start. If I put more than 2 credits on it will then start. However, none of the jump buttons or the joystick work. Any thoughts?

Thanks
 
I had this exact same problem with my ZK yesterday ( Zeke wouldn't jump ) jiggled the ground wires and all's good again....for now.


AAMOI....can you guys remember what colour the platforms are on the first coco. stage....in MAME they are red'ish ..but in my ZK they are purple .

So are the colours in MAME wrong, or are the colours in my ZK not right ?

Purple

Ground looks fine all the way around. Do you think this could be a ROM issue?

Did they meter out good for continuity? Looking ok means absolutely nothing at all.
 
I forgot to mention, I can get Zeke to move left and right using the test switches inside the coin door, if this means anything.
 
I am at a total loss on this one. I have checked for grounding issues, shorts and loose connections. Does anyone think this could be a rom issue?
