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 
on.
• The receiver probably has a serious 
problem.
• Don’t try to turn on the receiver. Call a 
Pioneer-accredited repair center to 
look at the problem.
FAN STOP blinks in the display 
and the unit turns off.
• Something is stuck in the fan and/or the 
fan is broken.
• Remove the foreign object from the 
fan. If you can’t do this and/or the fan 
is broken call a Pioneer-accredited 
repair center to look at the problem.
OVERHEAT blinks in the 
display and no sound is 
output.
• The receiver has gotten too hot.
• Turn the receiver off and allow it to cool 
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.
THDCT NG blinks in the 
display and the unit turns off.
• The thermistor (temperature sensor) is 
broken.
• Turn the receiver off, unplug from wall 
and call a Pioneer-accredited repair 
center to look at the problem.
