There is no video
on the TV screen
Verify that the TV is powered on and set to the
appropriate input source for the set-top.
Verify that the set-top is powered on and tuned to an
authorized digital TV channel.
Verify that all video cables between the set-top and
the TV are firmly connected.
Verify that the coaxial cable feed is firmly connected to
the set-top and the wall jack.

The set-top is
making a humming
noise.
The set-top includes an integrated hard drive and a fan
for cooling. During normal operation, the set-top emits a
low humming noise, similar to a personal computer. The
noise varies in volume occasionally when the speed of
the internal fan adjusts to changes in the temperature
around the set-top. Please note the hard drive will stay
on even when the set-top is turned off.
