Possible Reason
The receiver has a time-out feature
that closes any menu after several
minutes of no activity. This will
discard any changes you have made,
but otherwise does no harm to the
receiver.
Possible Reason
• The TV set may not be working
properly.
• If the TV and the receiver are
working properly, there may be
interference with the satellite
signal. The TV may be wired to
the wrong input.
• The TV may not be on the correct
channel.
• The TV may not be set to display
from the correct input.
• The TV set may not be working
properly.
If the receiver is connected to the
TV using only 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.
There may be interference from
other nearby electrical devices
(such as cellular telephones,
computers, microwave ovens,
radios, stereos, or TVs).
What to Do
Start over again.
What to Do
• Make sure that the TV set is plugged into an electrical outlet.
Make sure the outlet has electrical power.
• Make sure that the TV is turned on.
• If the receiver is connected to the TV using only the C
connections, make sure that the TV is tuned to channel 3 or 4
(whichever works best in your area) and that the receiver is set
to the same channel as the TV using the Modulator Setup
screen.
• If the TV is receiving the signal through coaxial cabling from
the C 3-4 output on the satellite receiver, make sure the TV is
H
tuned to the same channel as indicated in the receiver
Modulator Setup screen.
• Make sure that the TV brightness and contrast are adjusted
correctly.
• Make sure that the TV is connected properly to the receiver.
Make sure that the TV's text mode and closed captioned
features are turned off.
• If the TV is connected to the receiver using the RCA-type or S-
Video connections, make sure the TV is set up to display from
the correct connected input(s).
• Check that the system has been installed correctly. Make sure
that all required coaxial cables are in place, and check that all
cable connectors are tight and dry (for outdoor cables).
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 and Signal
Strength menu. 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.
• Make sure that the TV brightness and contrast are adjusted
correctly, and that the TV is working properly.
Make sure that the TV is connected properly to the receiver.
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 dish-to-receiver cable run length; if it is over 100 feet,
call your dealer or installer.
