SYMPTOM After about ten minutes in either the record or playback modes, the capstan motor
slows down or stops, resulting in the unit reverting to the standby mode.
CAUSE
Lack of lubrication on the capstan motor bearing leads to overheating the drive IC,
which then shuts down the unit.
ACTION
Remove the capstan shaft from the bearing and lightly lubricate.
If the above action does not cure the problem, the capstan motor will have to be
replaced.
