I recently got a refurbished replacement for a dead 722. I noticed that I would get a 004 error (missing channel signal) on certain channels like CNN at some times but not others. Did the usual reboot and check switch to no avail. I finally noticed that the error was present when the receiver was displaying tuner 2 but not when I switched to tuner 1.
Thinking it might be a cable or connection problem, I switched to cables for the satellite inputs and found that error was still only present on tuner 2. Since the error is independent of the cable connection, it makes me think the problem is with tuner 2 in the receiver and not the cable or connections. Plus, I never had this problem with the previous 722, nor the other receivers in the house.
Just wondered if anyone had any other ideas to check before I call Dish for another replacement.
