3-How can i enable this options ("INT-Wireless ,Web-Browser ,PVR" ) for my TV ?
Tnahks a lot :-* :-*

D6920 and D6960 are same TV model...
Why do you need to change the model, something is missing on yours?
Is this PN (plasma)?

i need PVR and web browser ,6920 doesn't have them
6920 is led Smart tv , 46d6920 led smart tv (limited functions ,no pvr ,no web browser ( )
