Troubleshooting
Before calling your service provider, review this troubleshooting guide. This information is to
help you quickly solve a problem. If your problem still exists, contact your service provider.
Problem
Possible Solution
The DCX set-top will
not power on
•
The DCX set-top has 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 of the external power supply 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
that unit is powered on. Unplug the power cord from the DCX set-top’s AC
outlet, plug it back it in, and then press the POWER button. 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.
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 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.
• Check the batteries in the remote control. Install new batteries if needed.
There is no audio
when viewing cable
channels
•
Verify that the mute button on 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.).
