I had picture for a few minutes and now the picture is black. I have a Dish HD 211 receiver. This is not good, I bought 50 feet a few months ago to run into a 2nd room.
I'm not sure what the limit is, but 50' may be far enough for it to need amplification in order to stay synched. Does this happen on the HDTV that the receiver is near, or just the one in the other room?
