When i pull up the guide and click on a show the screen goes black before the show comes up. This also happent when switching to previous channel and has even started just going black at times during a longer show or movie. Customer service says it's normal but there is no way, just started a couple of months ago and as gotten worse. I cleared most of the recorded shows to help because that is what i was told to do but hasn't helped. Any suggestions?

This question, "SCREEN GOES BLACK," is about DirecTV channels, programming, equipment, and sports.
