Troubleshooting
If you run into any problem using this stereo
system, use the following checklist.
First, check that the power cord is connected
firmly and the speakers are connected
correctly and firmly.
Should any problem persist, consult your
nearest Sony dealer.
General
The display starts flashing as soon as you
plug in the power cord even though you
haven’t turned on the system
(demonstration mode).
•Press DISPLAY (for LBT-LX90AV/
LX9AV) or DEMO (STAND BY) (for
LBT-LX10AV) while the system is off.
If the system is in the Power Saving
mode, press POWER SAVE/DEMO
(STAND BY) (for LBT-LX90AV/LX9AV).
The demonstration appears automatically
the first time you plug in the power cord,
or if there is a power outage lasting
longer than half a day.
The clock setting/radio presetting is canceled.
•The power cord is disconnected or a power
failure occurs for more than half a day.
Redo the following procedures:
–“Step 3: Setting the time” on page 9.
–“Step 4: Presetting radio stations” on
page 10.
To set the timer function again, also redo
“Waking up to music” on page 41 and
“Timer-recording radio programs” on
page 42.
There is no sound.
•The jumpers for the DJ MIX jacks are not
connected (for European, North
American, and Mexican models only).
•Turn VOLUME clockwise.
•The headphones are connected.
•Insert only the stripped portion of the
speaker cord into the SPEAKER jack.
Inserting the vinyl portion of the speaker
cord will interfere with the speaker
connection.
•The volume level is automatically set to
the minimum during the Timer-recording.
Before placing a cassette in the
tape deck
Take up any slack in the tape. Otherwise the tape
may get entangled inside the tape deck and become
damaged.
When using a tape longer than 90
minutes
The tape is very elastic. Do not frequently change
the tape operations such as play, stop, and fast-
forwarding, etc. The tape may get entangled in the
tape deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use.
When the tape heads become dirty
— the sound is distorted
— there is a decrease in sound level
— the sound drops out
— the tape does not erase completely
— the tape does not record
Make sure to clean the tape heads before you start
an important recording or after playing an old tape.
Use a separately sold dry-type or wet-type cleaning
cassette. For details, refer to the instructions of the
cleaning cassette.
Demagnetizing the tape heads
Demagnetize the tape heads and the metal parts that
have contact with the tape every 20 to 30 hours of
use with a separately sold demagnetizing cassette.
For details, refer to the instructions of the
demagnetizing cassette.
