problem with seeburg disco was workingish then stopped

OK I bought this thing off a guy who didn't know If it worked or not.. I got it home plugged it in and low and behold it worked just had to find a loose wire to get the sound to work which I did. Then it was working OK didn't want to return the 45 but that was the magnet which was mia..anyways today I plugged it in and the selector screen says playing 200 and it won't do anything I can give it credits and it acknowledges that I am and I can select different records but nothing happens just keeps saying playing 200.. also the motor? At the bottom is really really hot.. it just won't move I dunno what to do...please help!!

Hi Luckyboy,
You'd best be "lucky"--apparently you have a model SMC-1 phonograph--If so, turn the power off now--before you read anymore ! The NIDEC brand motors "burn up", and or "seize", if left jammed for 10 or more minutes.
Once your motor has cooled down, add 20 wt. ND oil to the two oil cups--several times, prior to powering it up again.
After it has cooled down, and you have oiled it, turn the motor coupling so that the carriage moves at least one slot to the right, and re-power it up--see what it does, and let me know--If it returns to the jammed position, kill the power !
There are a couple of options at this point, including the brand new replacement MCU I build for the SMC's. PM me if you wish to purchase one.

That worked like a charm she is up and kicking again. Thank you so much I think you helped me a year ago? On my rockola 470 also you know your stuff.. do you know anything about this juke itself? I Googled it and got everything but what I was looking for like if it is worth anything or if I got a decent deal on it.. or something like that... it's a cool jukebox that's for sure..

Hi Luckyboy,
Glad to have "helped"(twice ??) !
Unfortunately, the problem you experienced, is bound to repeat itself. It was a constant problem with the SMC's. It could be a mechanism problem ("dirty", poorly adjusted 3M-1 contacts), or a PCC interface board problem--several "updates" were done to help--but none are 100% successful, as, most likely, the problem is in the MCU.
If you had asked me my opinion of that phonograph about 6 years ago, I would have answered about the same as I wrote in my "Seeburg Mechanism Guide"--very negative ! However, since the design of the new, "Gen 2, MCU" for that phono, I think it is the "best" Seeburg ever made !
I have a "test stand" SMC, here that has been running almost 24/7 for six years--no problems have shown up since we made the final version of the main chip, exactly 4 years ago, this month ! (like I said before, PM me if you wish to purchase a new MCU)

OK I got the thing working flawlessly with a neodymium magnet.. but here is my question and maybe you can help me.. my a side is super scratchy and poppy I'm pretty sure that's a needle problem but wanted to see if you thought anything different. .

Why don't you swap the needles and answer your own question ? Ron Rich

Duh lol apparently I'm losing it thanks that'll do it...

I am not into replacing parts that still work like they should ...but... Ron mentions his upgrade part for those disco machines . I had to get one from him for a customers jukebox . The best thing about the part is you can run your machine on random play just like a cd player does . My customer is real happy with this upgrade part .

Hi Ken,
Glad to make your customer "Happy" !---thanks for the "plug"--
