Not having the black screen issue, but one issue I am having is the Joey 4s losing internet connection even though they are connected to the Hopper via MOCA and the Hopper has an internet connection, works and even shows in the network status menu that the internet is connected, and the Joey 4 has a strong MOCA connection. Restarting the Joey 4 does not fix the issue. The only fix that seems to work is doing a restart on the Hopper. Again, the internet connection at the Hopper works and you can use apps on the Hopper, but just not the Joey 4 due to reporting the internet is lost. Also, regular television and DVR access from the Joey4 still work fine just not the apps due to the internet connection loss. I have had this system for 6 weeks and have not made it a single week yet that has not required a reboot of the Hopper to fix one issue or another. I don't mind beta testing but give me a discount or pay me for doing your work for you Dish. There is a reason I do not check myself out and bag my own groceries at the grocery store.
