Q: What to do about temporary loss of satellite signal, "frozen" picture, or picture breaking into blocks / pixels?
The image on your screen is frozen, blocky, or you see a message that says, "Searching for Satellite Signal (x 771).
Possible Causes:
Severe weather (rain, snow, hail etc.) may cause this issue.
There may be an obstruction to your dish (debris, snow, ice, etc.) or a building or tree that blocks your line of sight to the satellite.
There may be a problem with the cables running from your satellite dish to your DIRECTV
If the picture is frozen, blocky, or pixels, there may be a problem with the transmission from the source.
Solution:
Weather issues are usually temporary. Wait for the weather to clear and your signal should return to normal.
If there are no weather problems in your area, reset your DIRECTV DVR using the red RESET button behind the door on the
front of the receiver or by unplugging the receiver for 15 seconds and then plugging it back in.
You can also check all the cable connections between your DIRECTV DVR and the satellite dish for loose or broken connections.
If the problem is coming from the program source (for example, you see the problem on one channel, but not on any others),
wait for the broadcasting channel to resolve the issue.
If there are obstructions blocking the dish's clear view of the satellite, you should contact a professional to remove them or
a DIRECTV installer at 1-800-531-5000 to relocate your dish.
If your signal strength is lower than 70 (60 or lower on HD receivers) on most transponders in good weather, contact a
professional installer to realign your dish or call us at 1-800-531-5000.
