Troubleshooting
Troubleshooting guidelines follow. If problems still occur after performing the diagnostics, call your service provider for assistance.
Problem — If this occurs:
The set-top will not power on
Solution — Then do one of the following:
•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 power supply is connected to the set-top and an electrical outlet. Unplug the set-top from the electrical outlet, plug it back in, and then press the POWER button.
•If the set-top is connected to a switched outlet on another unit, verify that the unit is powered on. Unplug the power supply from the rear of the set-top, plug it back it in, and then press the POWER button. Use an unswitched outlet, if possible.
•Press the POWER button on the set-top’s 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 STB mode.
•Verify that there are no obstructions between the remote control and the set-top. Aim the remote control directly at the set-top front panel, not the TV or VCR.
•The angle between the remote control and the set-top may be too large. Stand in front of the 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 set-top front panel.
•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 set-top audio output is connected to the TV, verify that the mute button on the TV has not been pressed.
•If the 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 set-top and the audio playback device (TV, receiver, DVD player, etc.).
