i have a new 50 inch UE50ES6715UXXE with the same "problem". The RCA in the back is only for input. As i want to use some small external speakers that i used with my older tv. Only headphone jack also, must buy a headphone to RCA jack and test.
I have a 32 inch LA32D40E1MXXS. I'd like to hook up external speakers, but can only find a headphone jack. Am I missing something, or is there no audio out option (RCA jacks)?
