We have A Dish 625 DVR along with another 522? Receiver in another room. The 522 works fine. Today, out of the blue, when I turned the TV on, it says "no signal". Now, all the lights on the 625 DVR are on like they should be and it is even recording things (red light is on) at the correct times. The problem is, the signal is not getting to my TV. I: Restarted the DVR Checked all of the plugs to make sure nothing is loose Made sure the TV was on the correct input What could be the problem? This just happened out of the blue. By the way, to be more clear, the "no signal" message is the TV's message, I cannot see anything from my DVR at all. Thanks.
