I turn on Paragon, start a game, plunge... and then the first time I flip the flipper the game dies. The GI is still on but the scores go dark and the playfiled kinda flickers. Sometimes the game restarts.

I'm sorta new at repair so here's my questions.

1. Do you think it's the solenoid driver board?
2. If so is there a guide on how to check the parts on the board with a multimeter? I know I can buy a new one and swap it but I thought it woudl be more fun to learn how to repair what I have.

Thanks,

Coop

I doubled back. When you said it was the flippers I tried to find which specific flipper is causing the problem. It turns out that I can flip either flipper without any problem but if I flip them both at the same time the game shuts down? Does that give you any more infomation?

One month later. I finally just bought a new Alltek solenoid driver board. Unfortunately, I still have the same issues.

In the video below. I went to check the EOS switches and the playfield was just... possessed. I have no idea what would make it do that. The EOS switches seemed fine to me—they look like they might have some carbon build-up but the gaps seemed ok to me.

I checked the voltages on the new driver board and they were spot on so I'm at a loss. Can anyone point me in the right direction?

Lastly, I'll mention that I dripped the new board and played a full game. After I had walked away about 5minutes later I heard the game "click" and it had shut down just like before. Once I rebooted I was back to just hitting both flippers to kill the game.

Thanks for your help!

I'm trying to make my way though this guide.

It's a little over my head but I do see that my problem is called a reset issue. It's common yet there could be about a million things that could cause it.

However, I notice on the new solenoid driver board when I check the test points for the voltage the middle point read 16V on my multimeter. On the board it says that it should be 12v. Would this be an indication that the Voltage Regulator has failed?

You know this one got me thinking. the MPU was original and it was thrashed at the bottom with battery acid but it has worked for a couple of years with no issues so I assumed it was still good. I actually had an Alteck MPU in another game so I swapped that out and BOOM, it's fixed.

Thanks for the tip Quench . Also thanks to nplg BigAl56 mr2xbass hisokajp and TractorDoc for helping me get my Paragon flippin' again!
