TROUBLESHOOTING

The SDP-40HD does not power on.

1.Make sure the rear panel power switch is set to the I (“on”) position.

2.Attempt to power on the SDP-40HD with the front panel Standby button and remote control On button.

3.Examine the power cord to ensure a good connection between the rear panel AC input connector and the wall outlet.

4.Check the electrical circuit and breaker.

The remote control does not work.

1.Eliminate obstructions between the remote control and the front panel IR receiver. When the SDP-40HD is not using the rear panel IR IN connector, the remote control must be in line of sight with the front panel IR receiver for proper operation. The remote control might also become unreliable if strong sunlight or fluorescent light is shining on the IR receiver.

2.Make sure the remote control batteries are correctly inserted with the proper polarity.

3.Replace the remote control batteries. When the batteries are low on power, the remote control enters a low-voltage condition that prevents it from operating the SDP-40HD.

The SDP-40HD is powered on, but there is no audio.

1.Examine the audio cables to ensure a good connection between the source and the SDP-40HD, and the SDP-40HD and all associated power amplifiers.

2.Make sure all associated power amplifiers are powered on.

3.Make sure the SDP-40HD is receiving an audio signal. To do this, follow the instructions that begin on page 1-21to open the STATUS menu for the current input source.

4.Make sure the audio is not muted. The message “MUTE ON” or “FULL MUTE ON” appears in the on-screen and front panel displays when the audio is muted. To deactivate mute, press the Mute button or adjust the volume level.

5.Check the INPUT SETUP menu HDMI IN, DIGITAL IN, and ANALOG IN parameters to ensure the appropriate audio connector is assigned to the selected input.

The relationship between the HDMI inputs and analog and digital outputs depends on the settings of the DIGITAL IN parameter and the HDMI IN parameter. Refer to the table on page 3-7for assigning HDMI audio.

•When HDMI IN is set to NONE and DIGITAL IN is set to HDMI AUDIO, then the COAX-1 connector is automatically assigned to DIGITAL IN. This is in place of any previously assigned HDMI connector. Neither audio nor video will be available on the HDMI output.

•When HDMI IN is set to one of the HDMI connectors and DIGITAL IN is set to a parameter other than HDMI AUDIO, then both HDMI audio and video are active on the HDMI output connector.

6.The associated source device may not incorporate HDCP (High-bandwidth Digital Content Protection) encryption. HDCP is a copy protection technology incorporating an encryption and authentication scheme to protect certain digital audio and video content from being copied as it travels across DVI or HDMI connections. Since the SDP-40HD supports HDCP, associated equipment connected via HDMI or DVI (Digital Visual Interface) must also support HDCP. Check your manufacturer user guide to confirm HDCP compatibility.
