Happening
What’s Wrong What You Can Do
The receiver’s
front panel
POWER light
is on, but the TV
image:
• is black
(no picture),
• is frozen,
• has break-ups,
• has “snow,” or
• shows small
squares of
many colors.
• Maybe the TV set isn’t working right.
• If the TV and the receiver are working
right, maybe there’s interference with
the satellite signal.
• Maybe you wired the TV to the wrong
port.
• Make sure you plug the TV into an outlet. Make sure the outlet
has power.
• Make sure you turn on the TV.
• If you connect the receiver to the TV with only the TV Set Out
connections, make sure you tune the TV channel 3 or 4 (whichever
works best in your area) and set the receiver’s back panel channel 3/4
switch to the same channel as the TV.
• Make sure you adjust the TV brightness and contrast.
• Make sure you connect the TV to the receiver the right way and that the
TV is set up to display the right input where the satellite receiver is
connected.
• Make sure you turn off the TV’s text mode and closed captioned
features.
• Make sure you install the system the right way. Make sure all the cables
are in place, and their connections are tight.
• Make sure 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 you aim the satellite dish at the satellite.
• Check the strength of the signal with the Point Dish and Signal
Strength menu.
• Check the local weather. Heavy rain, snow, or cloud cover can interfere
with the satellite signal. Brush snow, leaves,
etc. off the satellite dish.
The receiver’s
front panel
POWER
light is
on, and there’s a
picture on the TV
screen, but the
picture:
• has sparkles or
is grainy,
• has a
herringbone
pattern,
• lacks color or
vertical hold,
or wobbles, or
• looks “washed
out” or fuzzy.
• Maybe the TV set isn’t working right.
• If you connect the receiver to the TV
with only the
TV ANTENNA/
CABLE IN
and
TV SET OUT
ports,
maybe there’s a strong local broadcast
on the same channel, or on a channel
next to the one where you tuned the
TV.
• Maybe there’s interference from other
nearby devices (like cell phones,
computers, microwave ovens, radios,
stereos, or TVs).
• Make sure you adjust the TV brightness and contrast, and the TV is
working right.
• Make sure you connect the TV to the receiver the right way.
• Check whether nearby devices are sources of interference.
• Make sure all the cables are in place, and their connections are tight.
• Check the dish-to-receiver cable run length; if it’s over 100 feet,
call the Customer Service Center for help.
• Change the receiver CH3/CH4 switch and the TV both to the other
channel (3 or 4) to eliminate the interference.
A “black box” fills
almost all of the
TV screen. Maybe you turned on the Closed
Captioned feature on the TV,
and put that feature into Text mode. Use the TV remote control and/or menus the TV displays ( not the receiver
remote control or menus the receiver displays) to turn off the closed
captioned feature.
The TV screen
is all blue. Maybe you connected the receiver to an
input on the TV that’s wrong for the
signal output from the receiver. Maybe a
VCR is causing the problem. • Check your TV user’s manual for the right TV input to use
for the signal from the receiver.
• Set up your TV to display the right input where your receiver is
connected.
• Make sure the receiver is on.
• If a VCR is installed between the receiver and TV, turn the VCR off to
loop the receiver signal to the TV.
