Fault and repair guideNo reel rotationA common fault with older machines is lack of reel torque. This can result in the machine shutting down in playback or record modes and the tape not being would back into the cassette housing after eject. The best cure for this is to replace the reel chassis. However, because of changes during production you may find that some other bits, such as springs, may need replacing as well. Sony also made available a 'motor mod kit' which consists of a .02mm thick piece of plastic which can be fitted in the worn bearing. Alternatively a small ball bearing can be fitted but this may require the rotor to be filed down to ensure the correct gap between rotor and stator coils.Audio level controls not operatingCheck that the audio monitor is set to Auto. The VU meters only show the Hi-Fi sound level in this mode.Deck goes into rewindThis can be caused by failure of the tape end sensor. You can check this by unplugging the sensor at its socket on the PCB. |
Hall effect sensor attached with glue |
No head drum rotationYou may find that the head drum fails to rotate. This is due to a problem with the Hall effect device on the head drum motor which is secured by a blob of glue. Full details on how to fix this can be found on the head motor page. |
Broken gear (left)

Failure to load a tapeThe cassette carriage can fail to operate. This is caused by breakage of the plastic gears in the side of the mechanism. Often one of the teeth is missing.When this happens the faulty gears must be replaced and the mechanism correctly realigned so that the left and right side "tray arms" are at the same position relative to the front panel. This is done by releasing the plastic tab on the gear away from the motor side and selecting the correct mesh position with the teeth of the drive cog on rod which connects between both sides of the cassette tray. This problem is also found on the SL-F30, SL-F60 and the SL-HF77. |
