I recently picked up a working Paragon for free After replacing a couple of fuses, everything works except the displays. I did see them flicker on the first time I turned the game on, but have not been able to even get them to flicker since then. I have wiggled all of the wires and connectors to see if that might be the problem, but I can't seem to get anything out of them.

Can anybody tell me which connector is responsible for the displays on the board or a good place to start checking? I am new to Bally's after messing with Gottlieb System 80's for a while.

Do you know which plug controls the displays? That is kind of what I figured, but usually when you wiggle them on a problem like that something will at least flicker.

Yes I do, just need to know where to start.

Thanks, that is helpful!

rgr that. I am going to check voltages and report back

Well, voltages look good until I got to J3-8 on the solenoid driver board. I wasn't getting anything from that post. Fun thing happened though. Now the high voltage doesn't seem to be working at all as none of the coils on the playfield are working now and they were before. Checked the fuses and they are all fine. Oh well, that is enough for tonight. I will tear back into it tomorrow.

Good news everybody!

The displays are now working. It turns out that the little 3/16A fuse was blown. I got a remote fuse holder and a 1/4A fuse to test to see if that made a difference. I only had them on for a minute. Will that 1/4A fuse do long term damage? If so I will have to order the right ones over the internet and wait it out I guess. All of the displays lit up and look good aside from a missing digit on the player one display. The hundreds digit. However, I still do not have any power to the coils on the playfield. The game starts fine and switches work, but no go on the coils. I took all of the fuses out and checked them and they seem ok. So, anybody have a suggestion on where to check on that?

Thanks for the help so far!!
