Remedy
• The receiver may have a serious problem. Do not try switching the receiver
on. Contact a Pioneer authorized independent service company for help.
• There is a problem with the receiver's power unit or fan. Try turning on the
power after 1 minute. If the same thing happens, the receiver is damaged.
Unplug the receiver from the wall and call a Pioneer authorized independent
service company. (Other symptoms may appear when the power is turned on.)
• Allow the unit to cool down in a well-ventilated place before switching back
on.
• Wait at least 1 minute, then try turning the power on again.
• The power unit is damaged. Unplug the receiver from the wall and call a
Pioneer authorized independent service company.
Remedy
• Check the volume, mute setting (press MUTE) and speaker setting (press
SPEAKERS).
• Make sure the correct input function is selected.
• Check that the MCACC setup microphone is disconnected.
• Make sure the correct input signal is selected (press SIGNAL SEL). Note that
when PCM is selected, you won't be able to hear any other signal format.
• Check that the source component is connected properly (see Connecting
your equipment on page 14).
• Check that the speakers are connected properly (see Connecting the speakers
on page 18).
• Check that the Stereo listening mode or the Front Stage Surround Advance
mode isn't selected; select one of the surround listening modes (see Listening
in surround sound on page 52).
• Check that the surround/center speakers are not set to NO (see Speaker
Setting on page 94).
• Check the channel level settings (see Channel Level on page 95).
• Check the speaker connections (see Connecting the speakers on page 18).
• Check that the surround back speakers are set to LARGE or SMALL (see
Speaker Setting on page 94).
• Make sure surround back channel processing is set to SBch ON (see Using
surround back channel processing on page 55).
• If the source is Dolby Surround EX or DTS-ES with no flag to indicate 6.1
compatibility, then with surround back channel processing set to SBch Auto,
there will be no sound from the surround back speakers. In this case, set to
SBch ON (see Using surround back channel processing on page 55).
