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

not power on
The remote control
does not work
There is no audio
when viewing cable
channels
There is no audio from
the center and/or
surround speakers of
a home theater
receiver connected to
the DCH receiver
Possible Solution
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.
•
Press the POWER button on the DCH receiver front panel instead of the remote
control. The batteries in the remote control may be depleted.
•
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.
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.
•
Try changing channels using the buttons on the DCH receiver front panel.
•
Check the batteries in the remote control. Install new batteries if needed.
•
Verify that the mute button on the DCH receiver or the remote control has not
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.).
®
Not all Dolby
Digital programs feature full 5.1 surround sound. In some cases, the
programs may only contain left and right stereo audio.
•
Verify that the S/PDIF cable (coaxial or optical) is firmly connected to the DCH
receiver and the home theater receiver.
•
Verify that the home theater receiver is set to a surround sound audio mode
(Dolby Digital, Dolby Pro Logic II®, Dolby Pro Logic®).
•
Verify that the receiver is properly configured to work with all connected
speakers.
