Question about Audio Players & Recorders
The spindle motor in the cd player is not functioning properly. It won't even spin when a CD is inserted, just give forth noise. I tried to turn the shaft with my finger about 90deg, then it worked, and the disc directory could be read. The next time I inserted a disc again, the same problem happened. Also, it will suddenly stop in the middle of playing a song, displaying 'No disc'.
Is the motor brushless? Can you recommend a similar replacement of spindle motor for the model since the original is no longer produced? Otherwise, please advise other way to get around the problem.
Thank you very much.

Check the small signal transistors BC338 and BC328, they're under the transport mech and will be near where the spindle motor plugs in to the PCB.
One of the transistors acts as a brake which momentarily puts the motor in reverse polarity to stop the CD rotating during 'stop' or 'open tray' modes. The reason the CD is spinning backwards is that the transistor which drives the spindle motor forwards during playback is faulty and is triggering the braking transistor hence spinning backwards.
The transistors should be 'BC328-25' / 'BC338-25' (25v)
Replace these and all should be well.
Hope this helps

Well I fixed the problem myself by taking yhe cover off and cleaning the laser with a cue tip and alchohol very gently of course. I guess it was not reading the disc the first time it closed because some foreign object , works fine now
