I had service set up 2 weeks ago with a 622. TV2 worked great for a week then the remote would periodically fail to communicate with the receiver. Even when I was right in front of the receiver. As this became more fequent I used tips from this forum to try to help including switching to B range, changing the address, pigtail ect. Nothing helped. Now tonight I have had one brief moment of communications between the remote and the receiver but otherwise nada. Has anyone seen this before?
