wrong with the sound.
No audio
No sound is output when a
function is selected.
Cause
• The power plug is disconnected.
• The protection circuit may have been
activated.
• The protection circuit has been activated
because the lowest actual impedance of
the speakers (as opposed to the speakers'
rated impedance) is dangerously low.
• Static electricity caused by dry air.
• The speaker wires are frayed or sticking
out of the jack, and are touching the back of
the receiver or another set of wires.
• The receiver probably has a serious
problem.
• Something is stuck in the fan and/or the
fan is broken.
• The receiver has gotten too hot.
• The thermistor (temperature sensor) is
broken.
• The speakers have been incorrectly
connected (+/- connections are reversed).
• Improper connections.
• Sound is muted.
• The volume is turned down.
• Speakers are turned off.
• DIGITAL/ANALOG setting is incorrect.
• MULTI CH IN mode is on.
Techno Tidbits & Problem-solving
Remedy
• Connect the power plug to the wall outlet.
• Disconnect the power plug from the
outlet, and insert again.
• Turn down the volume.
• When it's convenient go to ACOUSTIC
CALIBRATION EQ (page 84–85) and lower
the 63 Hz and 125 Hz equalizer levels using
MANUAL setting.
• Switch the unit off, then on again.
• Disconnect the power plug from the
outlet, and insert again.
• Reinsert the speaker wires, making sure
there are no stray strands of wire and that
they are inserted fully (see page 24)
• Don't try to turn on the receiver. Call a
Pioneer-accredited repair center to look at
the problem.

If you can't do this and/or the fan is broken
call a Pioneer-accredited repair center to
look at the problem.
