Skeeball "Alley Hoops" Question

[Amigorick]

A neighbor gave me a working Alley Hoops Skee-ball machine. It had an issue with
the scoring display (not all segments illuminating) and the ball release solenoid.
I found a fuse directly under the ball release harness connection on the controller that
had blown. I replaced it and the ball release works.  I noticed while examining the
display (which has three digits on the left and the ball count on the right) that when I
wiggled the connector, all segments worked fine. I am planning on checking
for cold solder joints and possibly directly soldering the wires from the harness to the board.
I have checked with the diagnostics and everything seems to be working. The flasher, all
optical switches and ball release mechanism can be triggered through diagnostics.
When I reset the machine, I found that the machine will release the balls, but when I
roll them, it does not score anymore.  It was working fine before and I am stumped.
Does anyone have any type of schematics for this machine. I honestly don't know how old,
what "model" (S,H, etc) it is, or how much it is worth.
Any suggestions would be greatly appreciated !!

I don't have any schematics but I'd say as far as the score display goes, if they segments are separate bulbs in sockets like skee balls are, they sockets flex & the solder joint breaks.

Also if the fuse for the ball release solenoid blows often, the solenoid may be getting hung up which I find to be very common.

Who makes the machine? If they're still in business maybe you can get schematics from them, otherwise you may try either Betson or Weiner Distributing.

Edit: duh, I see Skeeball makes it. See if they will give you the manual.

Not sure it happened after reset but I imagine the score switches are optical.
Are they getting power (5 volts)?

One test is to take a digital camera such as your phone camera and look at the transmitter part of the score sensor and you should see the ir light.
Sometimes it'll be real weak and won't work.

I was tinkering with the Skeeball game and wanted to update the status.  When I place my hand in front of any of the
sensors, there is a corresponding led that illuminates on the small circuit board near the display.  They are triggering,
but it will not keep score. When I start the game by pressing the button, the game seems to go into "play" mode but rolling
the balls or triggering the sensors by hand has no effect.  I had originally planned on putting the game in my mother-in-laws
game room but it is too tall. I am either going to sell it or part it out. There are around ten extra sensors in a bag in the machine
that all work.Any ideas of what the parts are worth? I would love to get it working again and sell it whole.  I hope the main board
was not damaged when I replaced the fuse for the ball release actuator. After that, the machine stopped responding during play
mode. I have removed the fuse and tried it but no change.
It frustrates me that it was working fine !!  Could I have disabled the scoring when I was tinkering with the program mode?
I was adjusting it to turn off the ticket feed.  Thanks in advance for any suggestions !!!!!
