Advertisements I have two THDs as well - one in the main room with lots of activity and is fine -- the other is upstairs in bedroom with far less activity and had some gray screen issues and still needs a reboot every now and then. I think it is just some boxes have QA issues. We would need a lot of data here to track it down to production runs and so forth but my speculation is certain production runs just had issues. PS - the one in the bedroom I recieved from bonus points at work. Likely it is a refurb.
