Advertisements I have two Series II DirecTivo's. One is an R10 and the other a DSR708 so they are running slightly different software. They both are having the same problem that started at the same time a few days ago. When watching a program, there will be a sudden lost of signal (black screen) for about a 1/2-second, followed by a color problem for a couple of seconds. The color problem could be anything from going to black and white to a smearing of the colors. I can't imagine that this is a receiver problem in that they are both doing it. I'm wondering about my LNB's. My DirecTV dish is over 10 years old. Is this a symptom of LNB's that are starting to fail? It happens too fast to check signal strength.
