I would like to know if anybody is having this problem. When I checked out the dish home for the first time. I switched back or changed the channel and the screen went all black no sound and no picture. I heard some clicking going on in the receiver. I turned off the unit 3 times and then it was ok. Today 2 day's later my girlfriend turned it on while I was at work and called me to tell me the screen was all black and it wasn't working. Like I need to hear this at work. I told her to turn it off then back on again and then it was ok. What is up with Echostar software. What's going to happen when my 501 get's this upgrade?
