Bedroom dish reciever loses signal
We have Dish TV with vpn211z recievers. As long as main tv in living room is on the bedroom tv works fine. Shortly after turning off main tv the bedroom tv loses satellite sigal. We have unplugged and reset the reciever. It will reset, but eventually we lose the signal again. Occasionally the picture will go black but sound will remain. We have also checked all connections ( that we know of). Recievers are 3 years old. Any ideas?
