I have the same TV. Just set it up. Picture was not great at first but took it out of shop mode and put it into (I think) consumer mode and it works fine. Don't remember exactly how I did this. Just used on screen prompts as I recall. Know I didn't have to dig through the manual to find it. Hope this helps.
I bought this tv and when I went to firmware update and hit the info buttom this is what comes up
MODULE T-AMBAUSC-2008.9, DATE : PANEL : 46A 71, MICOM : T-AMBUSM-1005 RFS : T-AMBAUSC-20080416, 2008-10-15
the picture is terrible on this set, faces are washed out and the picture is not sharp at all. is this an A panel instead of an
S-samsung panel ?
This is the second tv of this model I have had and am so dissappointed with samsung
