yes I did and when one or two channels are working the only explanation is at your end not the customers. My internet is high speed and everything else works off the same router with absolutely no problems and I even bought a new reciever and it is exactly the same then what do you say now. The problem is called shedding the load and it is very common today. Some people believe that stuff that you are telling them but you are in my field now. If I had an internal problem all channels would be down and not one or two or three left on. Please turn them on and quit shedding the load to sell more. Thank you.
