Apparently this problem existed for quite some time. However, I just got my first 722 and placed it in the bedroom. At night, the receiver is turned off (stand-by mode), there are no recordings scheduled and I move the update time to 12pm, yet the fan just keeps working non-stop and it drives me crazy. I checked the temps and it had high 140, low 120 and average 86.
I called tech support and was hopping to get a replacement, but no, they have to send a technician. What is he going to do, tell me that this is normal? The receiver in the TV cabinet, but there are no back wall behind it and no doors in front of it.
Is there a way to stop it?
