5 TROUBLESHOOTING
Troubleshooting guidelines follow. If problems still occur after performing the
diagnostics, call the TRC for assistance, as described in the Introduction.
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
you 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 sensor 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.
•
Check the batteries in the remote control. The batteries in the remote control
may be depleted. Install new batteries if needed.
There is no audio when
viewing cable channels
•
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.).
