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 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. 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.).
