NSM City II blown fuse, carriage stuck to left. Please point me in a direction.
Hello,
I am brand new to this website and have a NSM City II that I've had for about 15 years. It's been a great machine and has worked flawlessly, except for the dry rubber drive wheel...
Two nights ago, I plugged it in and it came to life like normal. All of a sudden, before I selected a record, the carriage moved all the way to the left and got stuck there as the motor continued to turn and started clicking as the gear was slipping.
First off, I don't have a manual or schematic. I tried to order one from a "website" a few years ago for $49.00 and got ripped off. It never came and the seller never responded to me. That left a bad taste in my mouth.
At any rate, I opened up the main power supply board cover and removed both audio channel boards and the board with the "scan" button on it. I plugged it back in and noted that the motor in the carriage was still running and forcing it to the left.
At that point, I noticed that the fuse directly above the "Scan" button board was blown. I powered down the juke and replaced that fuse. I powered it back up and that fuse immediately blew again.
I unplugged ALL connectors going to this board, except for the power feed coming in.
I replaced the fuse and again the fuse immediately blew.
This leads me to believe that the problem is in this board someplace. As a added note, there are no 56V LEDs illuminated on the right hand side of the board. All LEDS on the left side are lit.
I don't see any obvious blown caps, burned resistors, or anything else.
Does anyone have any idea where I can start to look? Also, does anyone have a reputable source for a Manual/schematic?
Thank you so much, have a blessed day.
MK
