Regardless of any other issues, you should turn your receiver off at night (both green and blue lights ..1&2) Out of the factory your 722 is set to recieve program information every morning at 3 a.m.. Your receiver needs this info to know what it is receiving. I have been installing dish for a long time and have found that some tuners override and take the download anyway regardless if the tuner is on or off, and some tuners won't take it unless it is off.
