During playback of a Surround 
EX or DTS-ES source on the 
SBch AUTO setting, EX or ES 
does not appear, or the signal 
is not properly processed.

• The source may be Dolby Surround EX/DTS-ES software, but it has no flag to indicate it is 6.1 
compatible. Set to SBch ON (see Using surround back channel processing on page 59), then switch 
to the THX Surround EX or Standard EX listening mode (see Listening in surround sound on page 56).

During playback of DVD-Audio, 
the display shows PCM.

• This will occur when playing DVD-Audio material over the HDMI connection. This is not a 
malfunction.

The power turns off 
automatically and some 
indicator flashes, or some 
indicator flashes and the power 
does not turn on.

• See the Power section (page 98).

Cannot be remote controlled.

• Set a 5-digit preset code corresponding to the receiver to be operated in the remote control (see 
Operating multiple receivers on page 73).
• Check whether the receiver’s remote control mode is properly set (see Remote Control Mode Setup 
on page 96).
• Try replacing the batteries in the remote control (see Loading the batteries on page 9).
• Be sure to operate within 7 m (23 ft.) and a 30º angle of the remote sensor on the front panel (see 
Operating range of remote control unit on page 9).
• Check that there are no obstacles between the receiver and the remote control.
• Make sure that there is no fluorescent or other strong light shining on to the remote sensor.
• Check the connections of the CONTROL IN jack (see Operating other Pioneer components with this 
unit’s sensor on page 35).

Other components can’t be 
operated with the system 
remote.

• If the battery ran down, the preset codes may have been cleared. Re-enter the preset codes.
• The preset code may be incorrect. Redo the procedure for entering preset codes.

The HDMI indicator blinks 
continuously.

• Check all the points below.

No picture or sound.

• This receiver is HDCP-compatible. Check that the components you are connecting are also HDCP-
compatible. If they are not, please connect them using the component, S-Video or composite video 
jacks.
• Depending on the connected source component, it’s possible that it will not work with this receiver 
(even if it is HDCP-compatible). In this case, connect using the component, S-Video or composite 
video jacks between source and receiver.
• If the problem still persists when connecting your HDMI component directly to your monitor, 
please consult the component or monitor manual or contact the manufacturer for support.
• If video images do not appear on your TV or flat panel TV, try adjusting the resolution, Deep Color 
or other setting for your component.
• While analog video signals are being output over HDMI, use a separate connection for audio 
output.
• When this receiver reproduces MULTI CH IN audio sources with the HDMI setting set to 
THROUGH, you cannot hear audio output from all channels. In this case, make a digital or analog 
audio connection.
• To output signals in Deep Color, use an HDMI cable (High Speed HDMI™ Cable) to connect this 
receiver to a component or TV with the Deep Color feature.

No picture.

• Try changing the Resolution setting (in Setting the Video options on page 68).
• VSX-23TXH only: Set the HDMI output setting to the connected HDMI OUT terminal (in Switching 
the HDMI output on page 71).

No sound, or sound suddenly 
ceases.

• Check that the HDMI AV setting is set to AMP/THROUGH.
• If the component is a DVI device, use a separate connection for the audio.
• If analog video is being output over HDMI, please use a separate connection for the audio.
• Check the audio output settings of the source component.
