Glad to hear from you again, but for this kind of issue, because I don't have enough information on this model, you'll need to contact support for Samsung UK: http://www.samsung.com/uk/support/model/UE40ES6300UXXU
Hope this helps you!
I have bought a composite AV cable to play music from my iPod through my Smart 3D TV.
The videos and photos work but not the audio. When I press Source, it shows AV but when I click on this, it tells me to check the cables, source, etc - which doesn't make sense as the videos work.
When I tried it last night, eventually I got the music to play (don't know how as I didn't change any settings but today, I cannot get the music to play - again, the videos, movies and photos are working.
I have tried the cable on two Samsung televisions with the same result but it does work fine on an ONN tv!
Can anyone help, please?
