What Is Happening Possible Reason What to Do
The receiver’s front panel power
light is on, but the TV image is
black, blue, or snowy.
• The TV set may not be
working properly.
• The TV may be connected
to the wrong input.
• If the TV and the receiver
are working properly, there
may be interference with the
satellite signal.
• Verify the TV is set to the correct input or
channel for your setup.
• Make sure that the TV set is plugged into
a working electrical outlet.
• Make sure that the TV is turned on.
• Use the RECOVER button (page 88).
• Make sure that the TV is connected
properly to the receiver.
• Make sure that the TV’s text mode and
Closed Captioning features are turned
off.
• Make sure that the TV brightness and
contrast are adjusted correctly.
The TV image has pixels (small
squares), is freezing, or you have
intermittent black screens.
Your receiver may be
experiencing signal loss due to
something blocking your dish’s
view of the sky, the dish being
mis-aligned, or weather.
• Make sure that the satellite dish has a
clear line of sight to the satellite.
• Check whether branches or leaves have
grown into the line of sight.
• Make sure that the satellite dish is aimed
at the satellite. Check the strength of the
signal using the Point Dish screen, as
described on page 122. Consult your
installer to re-aim the dish, if necessary,
to obtain the maximum possible signal
strength.
• Note the local weather conditions. Heavy
rain, snow, or cloud cover may be
interfering with transmission of the
satellite signal. Remove any snow or
other debris which may have collected on
the satellite dish.
The receiver’s front panel power
light is on, and there is a picture on
the TV screen, but the picture:
• has sparkles or is grainy
• has a herringbone pattern
• lacks color or vertical hold
• wobbles
• looks “washed out” or fuzzy.
• The TV set may not be
working properly.
• Make sure that the TV brightness and
contrast are adjusted correctly, and that
the TV is working properly.
• If the receiver is connected
to the remote TV using the
RF or VHF connections,
there may be a strong local
broadcast on the same
channel, or a channel
adjacent to the one to which
the TV is tuned.
• Make sure that the TV is connected
properly to the receiver.
• There may be interference
from other nearby electrical
devices (such as radio
towers, cellular telephones,
computers, microwave
ovens, radios, stereos, or
TVs).
• Check other nearby electrical devices as
possible sources of interference.
• Check that all required coaxial cables are
in place.
• Check for moisture or water leaking into
all connections. Dry them out if needed,
then seal them with coaxial cable sealant.
• Check the length of cable between your
dish and receiver. If it is greater than 200
feet, contact the person who installed
your system.
• Make sure the system is properly
grounded.
