Had DTV genie with 3 clients hooked up yesterday. All went well. This morning, one of the clients wasn't working. Gave the "no signal" screen. Checked all connections, reset the client, later unhooked the client from power altogether and tried resetting that way. Called tech support...they had me repeat the above steps...then had me reset the Genie...nothing worked. I swapped a client box from another TV and it is doing the same thing. When I reset or hook up new client (the one I swapped from downstairs), the lights come on (Direct TV and network lights), gives message that it is starting up and will take a minute. Finally the two lights go out, and the "no signal" message reappears. 3rd client is working ok. I'm baffled...any ideas?
