Hi guys,

I bought a Hobbit pinball machine. To get this into the basement, we had to dismantle the playfield. Unfortunately, we probably did something wrong when plugging in the connectors.

After a short play (by a beginner), he gets pretty fast multiballs and also the orcs go up very quickly. The bumpers also trigger without a ball hitting them. Also I sometimes have a second ball in the shooterlane. It looks as if the control is no longer in order. The pinball does not show any errors in the test menu. I still have a Dialed in! pinball. Can I swap the big PCB of it with the one of the Hobbit to see if it is because of that? Or are there game specific parts included?
I added a video, which shows a part of the problem. It gets worse, the longer you play.

Thanks in advance, kind regards from germany

Thanks for your tips. Unfortunately, it's not that simple. We did check all the cables, of course. I should have mentioned that in the process we found that two of the three opto boards on J1 were broken, as was the opto receiver board on the 5-Ball through

I put a video in the dropbox again. When I did the switch test I noticed that on the rollovers and on the standup targets behind Dwarf several switches "light up" in parallel, is this normal?

Also the switches 66, 70 and 71 do not work (All Column 9 J202).
