I’m new to Dish’s Hopper/Joey machines. Our Joey will be playing fine and suddenly jump off channel, freeze up with a small tv picture in the upper left corner of my 55” tv about the size of an 8x10. The picture in that little rectangle isn’t even the channel we were watching. Resetting doesn’t clear the problem, because it will eventually do it again. No functions on the remote will work when this happens except the power button. We must turn off the tv then it will work until it does it again. The Dish folks have been out and the techs I call say everything looks good. Has anyone an idea what is going on, ‘cause they sure don’t.
