Maintaining the cassette deck

Troubleshooting guide

Performing routine maintenance helps keep your cassette deck operating at peak performance.

Cleaning the heads

We recommend that you clean the head assemblies, tape guides, capstans, and pinch rollers of both cassette wells after every 10 hours of use. For best results, use tape head cleaning fluid and long-handled cotton swabs. (Using alcohol to clean the pinch rollers may cause them to dry out over a long period of time.) Be careful not to press too hard during cleaning, because the parts are precisely aligned.

1Open the cassette well doors.

2Dip a swab into the cleaning fluid, and clean the surface of the heads.

3Using a clean swab, clean the capstan shafts, making sure to clean all the way around them.

4Using a clean swab, clean the pinch rollers, making sure to clean all the way around them. Use a clean swab to keep them from turning.

Demagnetizing the heads

Since tape is magnetic, when the tape heads and capstan shaft contact the tapes, they become magnetized over time, increasing distortion. Playing tapes on a player with magnetized heads and capstans can also deteriorate the recordings on the tapes. For best performance, use a head demagnetizer to demagnetize the heads and capstans of both cassette wells.

Check to make sure that the audio cables and system control cables are connected properly.

No sound from the system

Check that the volume is set at a proper level.

Check that the speaker cables are connected prop- erly.

Check that the input cable from the source compo- nent is connected properly.

Check that the shorting plugs have not been removed from the ADAPTER loop jacks.

No sound from one of the speakers

Check that the balance between the left and right speakers isn’t set too far to one side.

Check that the audio and speaker cables are connected properly.

The STANDBY light blinks, but there is no

Check that the speaker cables aren’t short-circuited— that is, the (+) and (-) wires aren’t touching each other. If they are, separate the wires.

A hum when you select the PHONO input

Check that the audio cables are plugged securely into the PHONO jacks.

Check that the turntable is grounded on the rear panel. The ground wire should be connected to the screw labeled GND.
