Power supply issue after NIMH tests ok.

[UNIMAN]

I really want to THANK YOU SO MUCH FOR EVERYTHING. When I replaced the battery and everything worked, I sent video to my friend. It was his dad’s and they All had tears,( I heard) then it took a dump and I feel awful. I’d give him a machine but he the memories. That’s why I will do anything necessary to get this going.
After I replace the cap should I try it or wait until the mosfet gets replaced too? I have thousands of caps, and other electronic be parts. Do You happen to  b know the specs that I would need so I can look in my pile and see what’s what? Thx.

[One last question, Do You know the model of this machine or where it’s hiding?

Universal's have no model number. Pretty much go by the mpu board number. The nameplate has a model number spot and it is blank until after 1990 I think. At that time Nevada required a date of manufacture and Universal stamped the year in the model number spot. That is why we see many say I have model number Y92, etc. The Y is for year.
Go figure!

And that topside 5vdc regulator. Check the pins solder joints to the board it is soldered to.

Once found a broken solder connection that caused same issue with the 5vdc.

Finally Solved, One of the screws holding the 5 volt regulator was loose. secured it and it’s working great now. THANK YOU ALL FOR directing me to the right areas to troubleshoot. That was perfect advice.
