The 46" units should have an in-home warranty attached to them. I'm not aware of information concerning a box. That said, I'm not a member of service, but I'll see if I can connect to them and get some progress on your unit.
I'm sorry to hear of the trouble. If you would, please post your Samsung transaction number here, and I'll have someone look into the situation.
We bought our 46" TV back in February of 2010...and just noticed it is loosing MANY pixels. Being that we do have a warrenty on the TV and it has not even been close to a year since we bought it..I called Samsung. I was told it has to loose over 8 pixels for them to do anything at all. Once I told them there is definately over 8 dead pixels they said they would send a technician. About a WEEK later..a woman called and said they would be sending a box with the equipment in it and to call them when the box got here and they would set up a time and day for the technician to get here. I still have not received the "box". When I called the service number yesterday they said they were waiting on Samsung, that they had sent three reminders to Samsung (as they don't send the box out until Samsung gets in touch with them and tells them what needs to be in the box). The guy told me to call Samsung and remind them. When I called the 1-800-Samsung number the woman was very rude and said WE have NOTHING to do with that you have to talk to the triage people and I have NO idea how you can get in touch with them. Wow. And she also informed me she doesn't see anything about an order being put in for a technician. Double wow. So now im sitting here with a practically brand new TV that is loosing pixels and Samsung won't give me anything to go with...what to do?!?!?!?!
