Solution — Then do one of the following:
•
The 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 set-top and an AC outlet. Unplug the set-top from the AC
outlet and plug it back in.
•
If the set-top is connected to a switched outlet on another unit, verify that the unit is powered on. Unplug the
power cord from the set-top's AC outlet and plug it back in. Use an unswitched outlet, if possible.
•
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.
•
Check the batteries in the remote control. Install new batteries if needed.
•
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.).
