Intermittent picture interruption with new 4K TV
Hello: I just recently upgraded to a 4K television. Ever since we hooked it up, the picture will disappear every so often. Sometimes the picture will go on up to an hour without interruption, sometime it will happen every 5 minutes. The salesman recommended I buy a 4K cable to go with the TV. DVDs work fine with no interruption. Could it be my cable box (Scientific Atlanta). Any information or suggestions would be appreciated. It's very frustrating watching a sporting event when the picture goes out at an exciting moment. Thank you.
