I have an RCA W40D20 which works fine when it is initially turned on, but after 10 mins of operation, it begins to flicker and after about 30 secs of picture flickering it goes blurry. The picture stays blurry for about 20 mins and then sometimes it flickers back to normal, but often times it flickers and toggles back and forth. When the problem occurs I can turn it off, wait 10 seconds, turn it back on and it works fine for another 10 mins.
I appreciate your guidance/advise.
Thank you.

The tuner is connected to Satellite connector. I recheck connection and it is correctly connected. Can the problem be with the TV tuner itself?
This happens each time I turn the set on
