Troubleshooting

Possible Solution
The DCX set-top 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 DCX set-
top and an AC outlet. Unplug the DCX set-top from the AC
outlet, plug it back in, and then press the POWER button.
•
If the DCX set-top is connected to a switched outlet on
another unit, verify that the unit is powered on. Unplug the
power cord from the DCX set-top's AC outlet, plug it back in,
and then press the POWER button. It is recommended to use
an unswitched outlet, if possible.
•
Press the POWER button on the DCX set-top 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 DCX set-top. Aim the remote control directly at
the DCX set-top front panel, not the TV or VCR.
The angle between the remote control and the DCX set-top
may be too large. Stand in front of the DCX set-top 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 DCX set-top
front panel.
•
Check the batteries in the remote control. Install new
batteries if needed.
Verify that the mute button on the DCX set-top or the remote
control has not been pressed. Press MUTE on the remote
control to restore sound.
•
If the DCX set-top audio output is connected to the TV, verify
that the mute button on the TV has not been pressed.
•
If the DCX set-top 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
DCX set-top and the audio playback device (TV, receiver, DVD
player, etc.).
