The SDP-5 does not power on.

1.Attempt to power on the SDP-5 with the front panel standby button and remote control On button.

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

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.Make sure the front panel IR receiver window shown on page 2-3 is not obstructed. The remote control must be in line-of- sight with the receiver for proper operation. Refer to page 2-9 for more information.

2.Make sure the remote control batteries are correctly inserted with the proper polarity. Refer to page 1-5 for instructions to install new batteries.

The SDP-5 is powered on, but there is no audio.

1.Examine the audio cables to ensure a good connection to the associated amplifier.

2.Make sure volume level is audible. Volume level can be increased with the front panel volume knob (2-3) or the

remote control VOL and buttons (2-14).

3.Make sure audio has not been muted. The message “MUTE ON” or “FULL MUTE ON” will appear on the on-screen and front panel displays when audio has been muted. To deactivate mute, press the front panel or remote control Mute button or

use the front panel volume knob or the remote control VOL and buttons to adjust volume level.

4.Check the INPUT SETUP menu DIGITAL IN and ANALOG IN parameters to ensure the appropriate audio connector is assigned to the selected input. Refer to page 3-6 for more information.

5.Make sure the SDP-5 is receiving an audio signal. To do this, follow the instructions that begin on page 2-18 to open the STATUS menu for the current input source.

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

Dialog sounds muffled.

1.If the speaker setup does not include a center speaker, make sure a custom – as opposed to a JBL Synthesis – speaker setup is selected. Then, make sure the CUSTOM SETUP menu CENTER parameter is set to NONE (3-29).

A humming sound is present in the audio.

1.If a cable TV connection is present, disconnect the cable from the wall outlet. If this eliminates the humming sound, a ground loop isolation device is required. Contact your dealer or the cable provider for assistance.

2.Disconnect components one at a time to isolate the problem. Once the problem is identified, make sure the associated component is properly grounded and connected to the same electrical circuit as the SDP-5.
