Had my hopper 3 and 4k joey installed a couple of weeks ago. Come home yesterday and had complete signal loss. Unplugged hopper and when came back on I had the blue screen of death. The blue screen ended up being the hopper somehow took out my sat/tv hdmi input on my Oknyo receiver. Plugged straight into tv and got back to the signal loss. Checked all connections. The joey in the bedroom could still see the hopper and dvr programs. Call dish and they said needed to send tech. I needed to call back to schedule appointment. I went out to dish after that and used a stick to tap on dish and switch. When came back in house it was working again. Not sure what to do now?
