Not every ball but periodically I have a problem where when you lose a ball there is a relatively long delay until the next begins. On occasion the color dmd is even completely dark. Feels like it is more frequent than it used to be. An example video attached. Drained and waiting. Any suggestions appreciated. Wondering if there is some sort of watchdog timer gone rogue. Error in the eeprom? Who knows? Thank you.

I want to mention this does have a pinsound (not sure how anyone can possibly stand factory on this game), color dmd, a replacement flipper board but I forget which. And an nvram which I also don't remember the type and will have to check.

Oh and the original pinwoofer kit with 8 inch sub which is also EPIC when combined with the pinsound and movie clips. But I don't think that is related to my issue.

Thanks for the quick replies.

Color dmd is powered by factory connection iirc. The Subwoofer and audio amps are powered by an additional DC supply which ties in at the ac switch. I think the pinsound board uses the factory connection too but I don't remember.

I will try a factory reset next chance I get.

I was not suspecting ball trough switches because the ball in play does appear to end immediately. I can look at that though. Sounds like there is one more between the main trough and the shooter lane to check too?

Yep I'll be sure to check that. I don't think I have heard balls "click" into place as if they were stuck but it could be right on the edge. I need to get a switch for the vuk as well.

This machine is at a buddies house at the moment but I'll check it in a couple weeks and get back to you guys.

Did a factory reset and examined the switches in the ball switch assembly. Nothing obvious. We will just have to see if the reset resolved it after some plays.

By the way on my particular machine I had to short eos to solve some flipper crapping out situations. I had tried new eos and the (aftermarket) flipper board was registering button presses. Finally got fed up and shorted them and now it seems fine.
