Look up Jeff Kohout, pinballpcb.com. He makes all new boards for Williams games, including Black Knight. Highly recommended...

Clive at www.coinopcauldron.com or www.ksarcade.com will test and rebuild your boards. Great service at both. I usually choose whichever one has the least backlog at the time.

I wonder if you can have Rob Anthony (LockWhenLit.com) look at it while you are up visiting at Pin-a-Go-Go. A win win so to speak.

Those old connectors were rated for 25 cycles, and you have probably long exceeded that number in a game of that vintage.

Sending your boards out is a good idea. New sockets and connectors will make that game reliable - but you will also want to replace the female pins in the connectors too for 100% bulletproofing.

Even refurbished, I hate that system 7 board set. That center connection is a pain in the ass.

You can send your boards out, probably pay a cool $150 without shipping.

Or you can sell your old boards to offset the cost of a brand new mpu/driver combo by Rottendog and be done with it (If your connectors are good)

It's a great board, I've never had any problems with it and it is dip swtich selectable for any game from that era.

I replaced all of BK boards with Jeff Kohout, pinballpcb.com, boards. I had put Rottendogs boards in it, but it was missing some of the sounds in it, a known problem I think. I would have liked to have kept the original boards but the cpu had so much acid damage that it could not be saved.

Can't recommend Kohout enough, replaced both the driverboard and soundboard in mine before I sold it. rock solid, works right out of the box with no issues, great lamp and switch troubleshooting with LED strips on the board. It's the closest you'll get to the stock board, but still have modern components in it.

These games were only designed to last 3 years.

They would pay themselves off in 3 months, and then you had 33 months before you threw them in the dumpster.

I've got mine on location, original boards. Just re-pinned the male and female connectors, and it runs great 12 hours a day. Cannot stress that enough with early solid state. Re-pin everything, or hire a professional to do it for you. Money well spent.

Connectors, connectors, connectors.

Lots of good option thrown out already.

I fix / bullet proof these WMS boards. I have done hundreds of them. I charge flat rates, warranties, 1 month turn around time.

Message me for info.

Thanks

Extremely high recommendations to barakandl's board repair skills. You will save yourself a few hundred dollars getting boards repaired over a new manufactured board which might not even work right, because plugs need to be re-pinned.
