Let me answer some of the questions here.
1. About the D5/7U models being included? Even though the bulk of the problems with the set's turning them selves on or locking up are related to the D4/6U models, I have run across several post in different forums about the same problems with the D5/7U, granted not as many as the D4/6U but still the same issue (locking up). They are NOT different generations, as there is only about 5 or 6 months difference in production so they all share much of the same internal components. About the only things that made them different was a newer panel and cosmetic design.
2. Since Thursday night I have had no problems with the set locking up or turning itself on. However, I also have not watched a great deal of tv this weekend either. I did watch a few DVD's and the Academy Awards last night, which looked outstanding in HD. I also have made sure not to leave my tv set on 5.1 when I go to bed either.
3. Sharp has called me back and pretty much ask me the same question as before, and I pretty much gave them the same answers. They wanted to know about the problems, what I have connected to the set, last time anything happened, where I purchased the set, and date.
4. What can you do? First thing I would do is have the NEW firmware installed! It can't hurt, and it might help some of the issues you have. We all have different setups and what might not work for me may be the fix for you.
Note, on which station or channel does your set freeze up on (EVERY SINGLE TIME) find a patteren. (For me it seem to be NBC digital 5.1) if it's more than one channel make a list.
Note, On which channel was your set left on when it turned itself on, and note the time AM/PM (EVERY SINGLE TIME) find the patteren. ( For me it's always NBC digital 5.1 in the AM, between 12 and 3am)
Note your setup, do you have Cable, Dish, OTA Digital, or Analog? What do you have connected to your set? DVD, VCR, DVR, STB, is your set connectd to a digital reciever for audio?
Where did you purchase your set? Date? Sharp will ask some of these questions but the more info you can give them on when, why, and how your set screws up will help them solve our issues with these set's.
