Before continuing with troubleshooting, check if the problem’s happening on more than one channel. If your picture problem’s only occurring on one channel, the problem’s likely to be with that particular broadcaster. Wait a few minutes and then try the channel again.
You should also check the Service Status page for any network outages in your area that could be causing a problem.
Finally, remember that bad weather such as heavy wind, rain, snow, or storms can interfere with your satellite signal. If the weather’s bad where you are, wait for it to return to normal to see if that fixes the problem.
