JVC TT-101 Won't Stop

The Stop button on my recently purchased QL-10 doesn't work. It worked at first after the TT warmed up, but then quit completely. I since have replaced all 37 electrolytic caps on 3 boards, but it made no difference. The power voltages are correct. The button itself is fine and shorts pins 6 and 9 of the P8 connector on the main board, but the motor doesn't stop. What could be wrong? Any particular transistor or adjustment? Please help! -Alex

Hard to get a good pics as the eyelets are small, silver bumps of solder. Some you really have to hunt for.  If not mistaken, the SM on vinylengine has a schematic of the board that shown the eyelets connecting points in dark grey, you can use it to map them out.

@gary7 what is SM? You have also replaced cables?  I notice that some seem new or fairly recent.


I would like to delete all the wiew wrap contacts and connect pins with contacts to detach; this would facilitate further maintenance by excluding all the tangle of cables.

Sorry, SM stands for service manual, as OM is for owners manual. I did not replace any cables. vinylengine.com is a great resource for turntable info and manuals.
