NSM Hit120 Jukebox circa 1970s. Fails to select and play.
Fails to select a play. Player tracks endlessly up and down. Have replaced Credit unit with a known serviceable unit. Have corrected dry solder connections on Supply board and all ribbon sockets and plugs.
Problem started with just failing occasionally. (Corrected by jiggling the two ribbon connections on the Supply board. Got progressively worse until all movement stopped. Had the Supply board and the credit unit checked by Tasmanian outfit. They OK'd the Supply and replaced the Credit unit with a repaired and tested unit. After installation I am now back to the endless tracking without selection. Any suggestions.

Sounds like the encoder on the mech. It's the black gear on the lower right that rotates through the box with the wires soldered to it. (right next to the white gear that makes the whole unit go left to right.) It uses an optical sensor to count the holes in the wheel/gear. It's not registering either because of the wiring or more likely gunk inside the unit blocking the optical sensor.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The top arm that swings over the spindle will control the automatic return. Leave the unit off. Swing the overhead holding top arm over and manually load a record. Now switch the top arm over the niddle spindle. Make sure that the switch is set for 7", 10" or 12" (45, 78, or 33). Manually place the tonearm at the start of the record and flip switch to 'play' (not reject or auto). It should play the whole record and automatically eject at the end and then shut off. Leave the arm swung over the middle after you loaded the record. Good luck. Let me know if you have any more questions.
1> be sure the service switch is in the PLAY position. 2> It's impossible to determine if the selections are not being written in to memory, or read out from the memory. it could be either. You most likely have to have the control center looked at, common with a machine this old. The capacitors in your control unit on the back door have probably gone bad, which they do after 25-40 years. Your jukebox is from 1960, so it's time to have both the amplifier and control unit rebuilt. Not what you wanted to hear, but it has to be done. If you're handy and can solder and read a schematic, you can buy the kits on eBay or do a Google search for Bill Bickers or Vern Tisdale. Both sell the rebuild kits.(Feb 27, 2010)
My suggestion is ask a friend etc with a turntable to try the new LP and see if it bounces on there's. If it plays your old stuff it most likely doesn't need a new stylus. Records are records they don't make them any different to what they used to. Check the new LP, is it warped does it have marks where it jumps?
1. power OFF
2. UNplug cord at wall
3. Turn ON jukebox (w/o power cord plugged in)
4. Turn OFF jukebox
5. Plug cord into SURGE PROCTOR (not wall, not simple power strip)
6.Turn ON jukebox.
7. If it doesn't work, try once more; otherwise ... *sigh* repair/replace..
YOU ARE SAYING THE MOTOR DOES NOT SPIN. TRY TO SPIN THE DRIVE SHAFT ON TOP OF MOTOR . DOES THE SHAFT TURN EASY. IF NO THEN YOU HAVE A MOTOR OR LUBRICATION. PROBLEM. DOES THE SCAN SWITCH, WHEN PUSHED TO SCAN DOES IT SCAN. IF IT SCANS BACK, AND FORTH 2 TIMES, YOU THEN HAVE A COIN CREDIT PROBLEM (MOST LIKELY ) ANSWER THE TWO QUESTION, OR STATEMENT. TO GET A MORE INTELLIGENT REPLY. YOU HAVE OVER 2000 PARTS IN THAT MACHINE. YOU HAVE GIVEN A (WHY DONT IT WORK QUESTION.)( there is no answer to the question. because of limited problem info)
Same key that operates the locks on the sides unlocks the top, but top might be sticky. Push down on it. Order keys if you don't have them. It's key F291. GOOD locksmith can make it or order one off eBay. Your jukebox is a USC2. Use that model number as a reference. Keypad "0" contacts are probably dirty or broken, or the connectors to the keyboard or black and gray boxes might be loose or need cleaning. Circuit board might be dirty (YES! This is a common Seeburg issue). To clean it of check for broken contacts on the "0" key, you'll have to remove it and open it up. Putting it back together can be tricky. Be patient. Worst case, you can install a replacement keyboard.
If you have someone come out, be SURE to have them give the jukebox a good lubrication. Seeburgs are complicated machines and need periodic lubrication.
Also, buy a manual. Jukebox repairmen don't usually have the manuals for your jukebox. Too many.
there is an opto sensor the gets blocked when the tone arm is at the end of the song. It looks like a black u mounted on a circuit board. The flag that interupts the sensor is on the tone arm. The opto must be dirty so it thinks it's at the end of the song and continues to the unload sequence dispite the tone arm having just started playing.
I had exactly the same problem and followed the OP's solution, which worked, but I couldn't hear the track as it was being recorded. So I tweaked the solution. If you do the following, you don't have to keep changing System Preferences as you switch from record to listening:
Go to System Preferences, press the Sound icon, and click on "Sound Effects." Then select the drop down menu and select "Play alerts and sound effects through selected sound output device" rather than the USB choice. Then click on "Output" and select how you want to listen; I used speakers so I selected "Headphones" where the port is "Built-in audio." Then click on "Input" and select the USB choice. Now record a track and you can hear it being recorded through your speakers (or headphones). When it's done recording and after the software transfers it to iTunes, you can play it again through your speakers without going to the preferences panel.
