What is the exact model number? And in what country did you buy the TV?
On my new samsung LED tv . I like to listen to my music collection off usb or sometimes internet radio. to my dismay i then found out i can't turn the screen of as the option is dimmed and not available.this doesn't make any sense as this is the only time i would normally use this feature to save energy.I could always do this on my lg tvs.Is there any chance that samsung might address this issue with a firmware upgrade.For the music player a simple icon for screen off would be the best.
