I notice my HR24/100 was on this AM**. Went to manually turn it off; nothing. Turned on the associated TV to be greeted with a blue screen which said in parts: Tried the reboot option, then RBR and then unplugged the HR24. Still the same screen. HD was making some very unusal sounds. So I'm sure the HD is toast. The unit is less than 6 months old. Any other suggestions? I have to call them later today, but my biggest fear is they will send me a refurbished unit. But I also seem to recall a post recently that said they are replacing defective HR24s with HR24s. Anyone know? **We did get the NR HD GUI last night causing the unit to turn on/restart.
