SMC-1 saga:

I'm trying to get a friend's Seeburg SMC-1 Disco working. She tells me it worked around seven years ago while she & hubby lived in Wisconsin. They bought it at one of the Chicago Coin-op Shows. Hubby was developing dementia shortly before moving to my neck of the woods in 2017. He apparently did NOT secure the mech for their 1000 mile move to Texas. When it arrived it would light up, displayed gobbldygook on the front panel but nothing more. Hubby passed away several years ago and the machine has sat silent ever since.

When I first checked it out (after boning up reading the manual) I asked if they'd ever changed the batteries. "What batteries??" she replied.  Oh my! I opened up the MCU box and a lot of "snow" drifted down! This thing was toast. I ordered an upgrade board from CDAdapter, installed it and then the fun began.

Upon power up the display shnows "- - - - - - - -" and stops. Does not show Your Selection, Selection Playing or "FP" for free play. Just dashes.

Mech was all the way over to the right side. Scan switch did nothing to move the mech in either Normal or Service modes.

I could put it into Service Mode and operate all of the functions with the new keypad/board. At least the display was working. When I put it into Factory Test Mode the Selection Playing display always shows "00". The #7 function is supposed to spin the motor. Nothing.

I tried to move the mech over to the left by hand-spinning the motor shaft. No movement.

Then today a nice person on the Seeburg FB group tipped me off to the trip solenoid lever. It was in the down (play) position. I flipped it up (scan) position and was able to move it to the center. Powered up but still all dashes on the display. I switched to Service Mode and it picked up a record and played it.. but did not reject it after play. Powered the box down and manually got the record back into the rack.

Still won't scan. Was able to get the motor to run using the #4 Factory Test function and #7 to turn it off.

Next I swapped out the PCC board with one I got from Victory Glass.. I'm trying anything at this point.

Not much different except Factory Test is acting like this: #1 Turns on motor #2 Turns on motor #4 Turns on motor @7 Turns on motor ..display consistently shows "00" in Selection Playing window.

Also, when put back in Normal Mode the motor starts spinning... but not scanning. I can get the motor to stop by flipping the Reject Switch. Powered down and tried to move the mech manually by hand-turning the motor shaft. Nope! Won't move with trip solenoid lever up or down.

So to recap: Both MCU and PCC boards replaced. Box does not complete power up showing correct info on display, just eight dashes. Cannot get mech to move left or right by hand-spinning the motor shaft.

I've reached the edge of my expertice and could sure use some sage advice.

Thanks for reading and perhaps offering ideas.
