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.

Setup
The setup screen doesn't

kind of error, or the settings
seem incorrect.
The LARGE and SMALL
settings for speakers after
the AUTO SURROUND
SOUND SETUP are incorrect.
• 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 output jacks haven't been connected
properly.
• The TV hasn't been connected to the
MONITOR OUT 1 jack.
• You connected your TV to the MONITOR
OUT 2 jack instead of the MONITOR OUT 1
jack.
• The PAL/NTSC setting is incorrect.
• The room environment is not optimal for
auto setup (too much ambient noise;
obstacles blocking the speakers from the
microphone; the monitor noise is
interferring with the setup; etc.).
• There are other frequencies in the room
that are affecting the auto setup.
• 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 (pages 99–101) 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 25).
• Don't try to turn on the receiver. Call a
Pioneer-accredited repair center to look at
the problem.
• 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.
• 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” (page 8) carefully.
• Turn the receiver off, unplug from wall
and call a Pioneer-accredited repair center
to look at the problem.
• Check all connections (see pages 16-23).
• Connect the TV to the MONITOR OUT 1
jacks (see page 16).
• Connect the TV to the MONITOR OUT 1
jacks (see page 16).
• Select the correct PAL/NTSC setting (see
page 8).
• Make sure the room environment is in
line with the guidelines for auto setup in
this manual (see pages 13–14, memos on
page 15).
• Check for household appliances (air
conditioner, fan, etc.) that may be affecting
the environment and switch them off if
necessary.
