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. Take a look at the other components and electrical appliances being used, because sometimes the problem may lie there. If the trouble isn’t sorted out even after going through the checks below, ask your nearest Pioneer authorized independent service company to carry out repair work.
•If the unit does not operate normally due to external effects such as static electricity disconnect the power plug from the outlet and insert again to return to normal operating conditions.
General
The power does not turn on.
Disconnect the power plug from the outlet, and insert again.
Make sure there are no loose strands of speaker wire touching the rear panel. This could cause the receiver to shut off automatically.
The receiver suddenly switches off.
When the Auto Power Down function is working, the power will automatically turn off if the receiver has not operated for several hours. Check the setting for the Auto Power Down function (see The Auto Power Down menu on page 33).
After about a minute (you won’t be able to switch the unit on during this time), switch the receiver back on. If the message persists, call a Pioneer authorized independent service company.
The power suddenly turns on or off, or the input suddenly changes (When the Control with HDMI is ON).
This happens because of the synchronized operation due to the Control with HDMI function. If synchronized operations are not needed, set the Control with HDMI to OFF (see HDMI Setup on page 34).

Check the audio output settings of the source component.
Refer to the instruction manual supplied with the source component.
No image is output when an input function is selected.
Make sure the component is connected correctly (refer to Connecting your equipment on page 10).
Use the same type of video cables for the source component and TV to connect to this receiver (see About video outputs connection on page 13).
Check The Input Assign menu on page 32 to make sure you’re assigned the correct input.
The video input selected on the TV monitor is incorrect. Refer to the instruction manual supplied with the TV.
No sound from subwoofer.
Make sure the subwoofer is switched on.
If the subwoofer has a volume knob, make sure it’s turned up.
The Dolby Digital or DTS source you are listening to may not have an LFE channel.
Switch the subwoofer setting in Speaker Setting on page 30 to YES or PLUS.
Switch the LFE ATT (LFE Attenuate) on page 28 to LFEATT 0 or LFEATT 5.
No sound from surround or center speakers.
Connect the speakers properly (refer to page 11).
Refer to Speaker Setting on page 30 to check the speaker settings.
Refer to Channel Level on page 31 to check the speaker levels.
The Phase Control feature doesn’t seem to have an audible effect.
If applicable, check that the lowpass filter switch on your subwoofer is off, or the lowpass cutoff is set to the highest frequency setting. If there is a PHASE setting on your subwoofer, set it to 0º (or depending on the subwoofer, the setting where you think it has the best overall effect on the sound).
Make sure the speaker distance setting is correct for all speakers (see Speaker Distance on page 32).
Considerable noise in radio broadcasts.
Connect the antenna (page 17) and adjust the position for best reception.
Route any loose cables away from the antenna terminals and wires.
Fully extend the FM wire antenna, position for best reception, and secure to a wall (or connect an outdoor FM antenna).
Connect an additional internal or external AM antenna (page 18).
Turn off equipment causing interference or move it away from the receiver (or move antennas farther away from equipment causing noise).
Broadcast stations cannot be selected automatically.
Connect an outdoor antenna (refer to page 18).
Noise during playback of a cassette deck.
Move the cassette deck away from your receiver, until the noise disappears.
No sound is output or a noise is output when software with DTS is played back.
Make sure the player’s settings are correct and/or the DTS signal out is on. Refer to the instruction manual supplied with the DVD player.
There seems to be a time lag between the speakers and the output of the subwoofer.
See Automatically setting up for surround sound (MCACC) on page 19 to set up your system again using MCACC (this will automatically compensate for a delay in the subwoofer output).
After using the Auto MCACC setup, the speaker size setting (LARGE or SMALL) is incorrect.
Low-frequency noise could have been caused by an air conditioner or motor. Switch off all appliances in the room and rerun the Auto MCACC setup.
