Troubleshooting
Incorrect operations are often mistaken for trouble and malfunctions. If you think that there is something wrong
with this component, check the points below. Sometimes the trouble may lie in another component. Investigate the
other components and electrical appliances being used. If the trouble cannot be rectified even after exercising the
checks listed below, ask your nearest PIONEER authorized service center or your dealer to carry out repair work.
The power does not turn on • The power plug is disconnected.
• The protection circuit may have been
activated.
• Connect the power plug to the wall
outlet.
• Disconnect the power plug from the
outlet, and insert again.
During loud playback the
power suddenly switches off.
• The protection circuit has been activated
because the lowest actual impedance of
the speakers (as opposed to the speak-
ers’ rated impedance) is dangerously
low.
•Turn down the volume.
• When it’s convenient go to ACOUSTIC
CAL EQ (see page 87) and lower the 63
Hz and 125 Hz equalizer levels using
manual setting.
• Turning DIGITAL SAFETY on may allow
you to turn up the volume a little more.
(From the Standby mode, and while
holding down the MULTI JOG CON-
TROL SET UP button press the
STANDBY/ON button. Each action
switches SAFETY ON or OFF.)
The unit does not respond
when the buttons are pressed.
• Static electricity caused by dry air. • Switch the unit off, then on again.
• Disconnect the power plug from the
outlet, and insert again.
During operation, the unit
suddenly switches off.
• The speaker wires are frayed or sticking
out of the jack, and are touching the
back of the receiver or another set of
wires.
• Reinsert the speaker wires, making
sure there are no stray strands of wire
and that they are inserted fully (see
page 25).
AMP ERR blinks in the display
and the unit turns off. The
STANDBY indicator will blink
and the unit cannot be turned

is broken call a Pioneer-accredited
repair center to look at the problem.
OVERHEAT blinks in the
display and no sound is
output.

down with good ventilation. It is very
likely that you have a heat dispersal
and ventilation problem so please
follow the instructions in “Installing the
Receiver” on page 2 carefully.
