I noticed on Sunday that a fan like sound was continuous on my 622 upstairs. I tried to turn it on to no avail. Wouldn't reboot from the power switch either. Unplugged it for a few minutes and plugged it in. The TV1 light would come on for a bit then off, then on, then off... Called DISH today. Seems like it's a continouous reboot and the 'fan' noise is the drive trying to spin up. Good thing my CSR was knowledgeable. He even used words like 'flash memory' and 'hard drive'! WOW! After trying a few obvious things, it becam clear the unit had died. The one time I did get it to reboot on Sunday, I managed to move about half my recordings to my hard drive. I guess I'll keep playing to see if I can get it to reboot once more. So long old friend!
