Sticker is usually seen through ventilation (inside) at top left side if you're looking from the back. Did you try to locate it with a flashlight?
Sometimes people say they can't find it, if it is so then the only other way to identify panel is to go to service menu.
To do that you should sequentially press info-menu-mute-power within 1-2 seconds with TV turned off. I don't know if this method works on American sets. (you can also try MUTE-1-8-2-POWER ON).
On the first page of menu you should find type string:http://5690.iz.piccy.info.nyud.net/i...6/605690/3.jpg
For example you have 40A1UF0C code:
40 - Inch
A - Vendor(A:Samsung, D:CMO, L:AUO, I:CPT, P:ChiLin, Q:IPS alpha)
1 - Panel frequence (6:50/60Hz, 1:100/120Hz, 2:200/240Hz)
U - Panel(A:AntiGlare, T:TN U:Ultra Clear)
F - Resolution (F:FHD, H:HD, U:UD)
0 - Panel 1st/2nd (1st:0, 2nd:1…)
C - BLU(BackLight Unit) C:CCFL, L:LED, E:Edge LED
Just don't change any parameters in service menu you don't understand.
