MCI JH-24 Counter problem

Hi All,
I am looking for info on how to solve the problem i am having with the counter on my tape machine. It is not stable, sometimes it will work, some times it will be off, sometimes it will stop working altogether.
I read on the MARA Machines site that he recaps the capacitor on the counter board. I can't find the board! I can see it in the manual, it has just one 15 uF/33 volts cap, i think. BUT WHERE IS IT?! Can you help?!

What year is the machine and which board are you referring to? Have you opened up the auto locater and checked for fried components, maybe a chip?

I can't see any reference to a "counter board" in the manual.
What is it called in your manual?
Display Board?

If the problem is intermittent then it won't be a capacitor.

Most likely the molex connectors. Have you reflowed all the solder joints on the motherboard molex connectors?
Does it have red IC sockets? if so they all need replacing.
