Sankyo Pochi center feature not working

[indianaterri]

I have an early modern Sankyo Pochi. Same one from the ticket before. But now, the center feature doesn't light up, and balls dropped into the bottom three pockets don't light up and payout.

I thought it worked when I picked it up, so something has jiggled loose.

I'm trying to chase down anything loose. And will pick up a multimeter this weekend.

Anyone have luck opening up and fixing the center of one of the early modern pachinkos?
Any advice?thumbnail_IMG_20200821_112413.jpg

I have the opportunity to have 2 machines of the same kind, one works, one doesnt. So they are sitting next to each other.

The one that doesnt work has a whine when I start it. And the motor in the bottom right that operates a mechanism runs slower.

Does sound power related. Does the shooter and everything else work?

Yes the shooter works, and lights on the side work. Also bottom right motor whirs away. I've a video here



The Pochi machines are sitting right next to each other. The one on the left, has the dark center feature. The one on the right has a working center feature.

They both have working shooters.
