INDICATION CAUSE REMEDY/CHECK
After cylinder lock is detected, the cylinder
does not start rotating again even after tape
unloading. Check the cylinder motor drive circuit.
Cassette tape is not wound up during the tape
unloading except EJECT mode. Check the capstan motor drive circuit.
Mechanism locks during mode transition
except EJECT mode.
1. Check the loading motor drive circuit.
2. Check the mechanism phase alignment.
3. Check the mode switch.
Mechanism locks during tape unloading.
1. Check the loading motor drive circuit.
2. Check the mechanism phase alignment.
Mechanism locks after tape unloading in
EJECT mode.
1. Check the loading motor drive circuit.
2. Check the mechanism phase alignment for cassette holder
During recording mode, recording signal is
less than the normal condition. Protection of the over-current flowing in
transistor which produces the power supply
for recording mode.
Recording circuit works except recording
mode. Check the recording circuit.
Cylinder lock detection. Check the cylinder unit and the cylinder motor
drive circuit.
Supply reel mechanism lock detection Check the supply reel mechanism and the
supply reel circuit.
Take-up reel mechanism lock detection Check the Take-up reel mechanism and the
