Possible Solution
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, 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 that unit is powered on. Unplug the power cord from
the 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 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 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.
•
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.).
