It varies a bit but try to find the menu to put it in home mode.
I have just purchased an UE40ES8000 tv set, and everything goes well, except that I cannot save the broadcast sound language setting for tv digital channels. I live in Spain but I want to have this option set to Original Version language (Sound menu). But after setting this, powering off, and about 10 sec from powering on, the setting returns to Spanish. The default system language settings have been set to English (System menu), updated the firmware, but the issue still occurs. I've contacted Samsung Support, but still waiting for the response.
Anyone have experienced the same problem?
