Just received my Samsung LN46A650A1F and this forum was invaluable in my purchasing decision. Not only did the report(s) that the spontaneous reboot problem had been solved but the information on Amazon's 30 day internal price match saved me an additional $36.50, so Thank You all.
First of all I used PaulLemonhead instructions for finding my firmware version and here it is exactly as listed on the bottom of my screen: MODULE:T-AMBAUSC-1003.M,DATE:PANEL:46A1,MICOM:T-AMBAUSM-1004RFS:T-AMBAUSC-20080212,2008-04-09
First of all the picture is gorgeous and I have none of the picture problems reported by some posters. No color saturation, bleeding, Purple tint, or "flashlight" artifacts. I will admit that I am hooked of my cable companies HDTV offerings since they are so beautiful and I find it hard to watch SD. In fact I called them up and upgraded my service to include ALL their HDTV offerings.
Sound is awesome and in fact the on board speaker system is louder than my Sony Home Theater System, HT-DDW790.
I did not receive the "scroll wheel" remote that everyone complains about. My TV came with an Ipod type center button remote. But that being said, the on screen menus are my only complaint about the A650. Some posters talk about playing games on this unit and if they want to play games then there is a built in one in my unit. In order to get the on screen menus I have to "catch" them as they scroll through. If I am not quick enough it will go to one below or above what I wanted, then of course I will have to hit RETURN to try again. The menus appear to "float" on the screen and this contributes to the problem. It is annoying but not a war stopper.
I love the TV and recommend it without reservation
Finally, my only disappointment is that I cannot get my Harmony 520 remote to control the A650 since there is no provision for the SOURCE button on the 520 to mimic the SOURCE button on the supplied remote. Despite repeated attempt to "train" the 520 it will not be recognized by the A650.
