GOOD LUCK GETTING YOUR PROBLEMS FIXED. I AM SURE IT IS FRUSTRATING WHEN RECEIVERS FAIL, I AM HOPING MY RECEIVERS DON'T EVER CAUSE ME ANY PROBLEMS. I HAD A DVR 625 FOR A COUPLE OF YEARS THAT NEVER FAILED ME, HOPE MY TWO 722KS DO THE SAME.
HAVE YOU BY ANY CHANCE PULLED THE PLUG ON THE RECEIVER, WAITED ABOUT 15 SECONDS, AND PLUGGED IT BACK IN, TO SEE IF IT WOULD DO ANYTHING
