Was chasing down a problem on my Paragon and created another. Was losing power to parts of the playfield and noticed some loose connections on J1 of my solenoid driver board. I replaced the connectors and removed the board to clean up any cold solder joints.

When I replaced the board the game starts up, boots correctly but I have no displays. Also no bumpers or slingshots are active during play. When I place in test mode I have nothing in displays. When I go into solenoid test all bumpers and slingshots fire. Any idea what I did here? Fuses seem to be fine.

Also swapped in the solenoid driver from Silverbsll and same symptoms.

Appreciate the help!

Forgot to mention I swapped the solenoid board from Silverball mania in to see if it made any difference and it did not.

I checked and replaced all fuses. I haven't checked test points yet. I have a frontier and silverball here. Can I temporarily swap either of those in? There is currently an Altek mpu in paragon.

I reset some of the connectors I replaced in the J1 connector of the solenoid driver board. I now have displays and one of 3 pop bumpers work. Slingshots work occasionally. Can all this be a symptom of incomplete work on that connector?

Again when in self test all pop bumpers fire and slingshots work. In game I only have the upper left pop working and bottom right sling (intermittently working)

Any help?

Also put the solenoid driver board from paragon into my silverball and silverball worked perfectly. I do have an altek mpu in my silverball I can swap into paragon if needed.

Just for background. I didnt have these problems before I repinned the J1 connector. The game would start and function normally but the solenoids on the playfield would lose power mid game. I noticed lose connectors on J1 so started there.

I'm thinking this has to be the culprit. I have a ratcheting tool and .100 connectors. I struggled in the beginning not to crush too much of the connector so maybe have some lose connections still.. I will go through them all again.

Thanks
