I was watching the PGA tournament yesterday afternoon but this morning my 622, which serves the den and bedroom, wouldn't wake up. No green panel light despite repeated pressing of the remote buttons. Front panel power button got a brief green light and it tried to reboot. So did pulling the plug. I could hear either the hard drive or a fan on low speed but the unit just wouldn't boot up. Finally called Dish Tech support. The woman couldn't have been nicer. Since I couldn't get the unit to boot, I couldn't give her the receiver number. Asked if I could give her the number of my other 622 that works and deduce from that which one wasn't working. "Sure, that will work," she said. Told her what I'd already done. "You've done everything possible. I'm going to send you a replacement receiver," she said. Haven't had to call Tech support for a long time. I remember being so frustrated when they would make me repeat all the troubleshooting I had done before calling them. Today was the way it ought to work. This is actually my newer 622 installed 5 years ago. I had experienced what we used to call "the black screen of death" twice recently but no other indications of problems. Fortunately nothing on the hard drive of this one I mind losing, but I guess I ought to get an EHD and archive recordings from the other 622. I do want to keep some of those. RIP old 622.
