I've had HDMI problems since some time in late Feb, didn't have any for a year and a half before that. When I first turn on the TV I get no picture, if I unplug and replug the HDMI then it works fine until I turn it off and back on again. I called Dish and they replaced my 622 with a 722, I still have exactly the same problem.
Do you think this could be related to the new software?
