Troubleshooting
Before going through the check list below, first make
sure that:
The power cord is securely connected.
The speaker cords are securely connected.
Should any problem persist after you have made these
checks, consult your nearest Sony dealer.
The tone arm skips, skates or does not advance.
b The turntable is not level. Place the turntable on a
level surface.
b The record is dirty or scratched.
Clean the record with a commercially available
record cleaning kit, or replace the record.
Poor sound quality, excessive noise, intermittent sound,
etc…
b The stylus is dirty or worn. Remove dust on the
stylus using a stylus cleaning brush, or replace the
worn stylus (see page 7).
b Dust or dirt has collected on the record. Clean the
record using a good quality record cleaner.
Rumble or low-frequency howl*.
b The turntable is placed too close to speakers. Move
speakers away from the turntable.
Platter does not rotate.
b Make sure the power cord is inserted all the way into
an AC wall outlet.
Sound is too low or distorted.
b The turntable is not connected to the PHONO inputs
on the amplifier (see page 5).
b Set MM.AMP. ON/OFF to the appropriate position
(see page 5).
* This phenomenon, called “acoustic feedback”, occurs
when vibrations from the speakers are transmitted
through the air or via solid objects (such as shelves, a
cabinet, or the floor) to the turntable where they are
picked up by the stylus, amplified and reproduced
through the speakers.
