I have a Samsunt Smart TV model number UE40D65110WSXXH and Samsung Home Theatre system model HT-D350. An optical cable connect from the Digital Audio Output Optical slot to the Audio Input Jack in the home theatre. An HDMI cable runs from the HDMI 4 slot into the theatre system. A Scart connection hooks up to an additional, older CD/VCR player.
When I play DVD movies and music DVD's all speakers work. When I watch TV or the old VCR or a movie on a pendrive, only 2 speakers work. If I listen to music with the home theatre, the TV screen comes on automatically and shows the Video, Photo, Music and Settings screen relative to the theatre. Once the Music starts playing, that screen goes away and the Samsung logo bounces across a black screen like on old Pong game screen. I can't just listen to music with the TV screen on, or so it seems.
I'm happy with the systems, just think some things are working right due to lack of knowledge on my part as far as setting the right programs.
Really appreciate your continued support.
