5 TROUBLESHOOTING

Troubleshooting guidelines follow. If problems still occur after performing the

diagnostics, call the TRC for assistance as described in the Introduction section.

Problem Possible Solution

The DCH receiver will

not power on

The DCH receiver may have received a software update and may not power on while

the new software is being installed. Try again in a few minutes.

• Verify that the AC power cord is connected to the DCH receiver and an AC

outlet. Unplug the DCH receiver from the AC outlet, plug it back in, and then

press the POWER button.

• If the DCH receiver is connected to a switched outlet on another unit, verify that

that unit is powered on. Unplug the power cord from the DCH receiver’s AC

outlet, plug it back it in, and then press the POWER button. It is recommended

to use an unswitched outlet, if possible.

• Check the batteries in the remote control. The batteries in the remote control

may be depleted. Install new batteries if needed.

The remote control

does not work

• Verify that the remote control is in “Cable” mode.

• Verify that there are no obstructions between the remote control and the DCH

receiver. Aim the remote control directly at the DCH receiver front panel, not the

TV or VCR.

• If using an external IR senor connected to the EXT IR input on the rear panel,

ensure the cable is properly connected to the rear panel input and that there is a

clear line-of-sight from the remote to the sensor.

The angle between the remote control and the DCH receiver may be too large. Stand

in front of the DCH receiver and not too far to either side.

• Press and release operation keys one at a time, firmly and deliberately.

may be depleted. Install new batteries if needed.

been pressed. Press mute on the remote control to restore sound.

• If the DCH receiver audio output is connected to the TV, verify that the mute

button on the TV has not been pressed.

• If the DCH receiver audio output is connected to a home theater receiver, verify

that the receiver is set to the appropriate input source and the mute button on

the receiver has not been pressed.

• Verify that you have the correct cables for the audio connections.

• Verify that the audio cables are firmly connected between the DCH receiver and

the audio playback device (TV, receiver, DVD player, etc.).

There is no audio from

the center and/or

surround speakers of a

home theater receiver

connected to the DCH

receiver

Not all Dolby Digital

programs feature full 5.1 surround sound. In some cases, the

programs may only contain left and right stereo audio.

receiver and the home theater receiver.
