    I have Samsung UE43NU7442
    and UE55NU7442 TVs, Any idea how the Date of Purchase gets there in the Service Menu?
    You mentioned SW updates can ruin the TV on purpose to make us go out and buy a new one, is it possible to manually update the SW to a previous 'good' version?

    To change Smart Hub region:
    Reset the Smart Hub and when you get to the T&Cs page do one of these sequences:



    FF > 2 > 8 > 9 REW

    You then get a list, scroll to UK or whatever country you want the Smart Hub apps from.

    If like me you are persecuted by the TV Plus crap endlessly looping movie trailers, disable it:
    Service Menu:

    Then: MRT Option > TV Plus Support > TV Plus Support OFF

    Bluetooth speaker was was enabled. Thank you. Someone also said you can reset HDMI signal errors in there. Is there a guide on how to do that? Also what does the 3D feature do? Display 3D movies or something?

    Hey does someone know how to change region from one country to another? Could not find this in hidden menu. There is PAN Euro region and not possible to change between cuntries which limit access to apps to only country you bought tv set 🙁

    Is it possible to completely disable the internal TV Speaker from this menu so that HDMI-ARC never has the capability to default to it on power on? Or a way to set Optical as the only output possible? I found a few options that sounded like they could be associated with that but didn't work.

    Ours 49NU7300 , Was able to enable BT by info, settings, mute then power, But after that, TV can't see any bluetooth devices( phone, speaker and mic , but these 3 see each other ) , any solution?

    I have a 75" Samsung NU8000 Series (UN75NU8000FXZA). I tried the Mute, 1, 8, 2, Power using an old Bright House Networks (Spectrum) universal remote and it would NOT work (Even though the mute button, number buttons, and power buttons work separately). I finally found an old Samsung remote. Did the Mute, 1, 8, 2, Power and it instantly works! Weird Flex, but okay. Thanks!

    Is there a way to disable HDR? With HDR you get a terrible dark picture on netflix etc., don‘t like it at all. What happens if you disable „HDR PLUS SUPPORT“ on that menue?

  9. Ash Chauhan

    Doesn't work on 43" NU6900. Service Menu changes made in MRT option and Engineering. The Blue tooth speaker option appears in Sound Menu but then TV searches but is unable to detect the Bluetooth speaker/s. Any ideas?
