I have a customer who I installed a Hopper w/sling and 2 Joeys. Shortly after the install he called and said Joeys are not working. After rebooting everything and replacing the node everything was working, Next day he calls and said the Joeys were black screened again, replaced Joeys and node again and all was good. Next time he called Dish who sent someone out and told the customer that the sat dish was out of align (not likely )..Hopper continued working through out the whole time. A day later he calls again, same thing, dead Joeys. I went back and replaced node and connected a tap behind the Hopper and connected Joeys to that. Everything working again, next day Joeys dead. Went back and replaced Hopper. Next day got the same call again. At this point I am out of ideas except to try replacing the cables from the dish to the node even though the Hopper continues to operate. He has been really good about this but afraid he might switch to Direct and we lose a good customer. I going back tomorrow but really have no idea what else to try. I need some input from you guys on what else I can do. would setting Hopper back to factory settings help? I saved the old Hoppers settings to the remote before replacing it and then restored setting to the new Hopper.
