This ability to turn off the screen when playing music is very useful when using applications like TuneIn. Even when playing music from youtube, many times you want just to listen, not to watch. Also, for many youtube music videos, picture is static.
I saw that this functionality was available for Samsung TV models until recently. For example: Turning off the picture but not the sound (2013-2015 TVs).
From some reason, this is impossible in my brand new UE55MU9000. If this is true, I believe that Samsung can provide such functionality in one of the next software updates.
It should be a standard feature of all TVs, there is no issue turning the backlight off, in fact it goes off everytime there is an all black picture on the screen as part of dimming.
I've always had this feature on LCD TVs of the past.
Getting Samsung to listen and add it to existing TV's that don't have it now, I wouldn't waste your breath :-)
Yes, I'm very unhappy that this feature is no longer available. I like to listen to music while I'm going to sleep, but I can't use the TV anymore because the light of the screen saver is so bright it keeps me awake. If I had known about this problem, I wouldn't have bought the TV.
Of course this would be a great feature. LIstening to music or TED talks. Saving power costs for Blind users. I cannot figure out why they would REMOVE this.
