Secret Menu Unlocks Bluetooth in Samsung Smart TV 4K UHD Series 6 640D



Let’s say you purchased a brand new Samsung Smart TV 4K UHD Series 6, 640D at your local COSTCO and there is no Bluetooth capability in sight…  Such an expensive TV, but NO Bluetooth???  How are you going to pair up your new Samsung, Sony, JVC, or Beats Bluetooth Headphones?  Well, don’t despair, you are in luck, there is a SECRET MENU that unlocks the Bluetooth capability of your Samsung Smart TV.

Here are the instructions:

  • Step 1: While your TV set is turned off, press the following on your remote control quickly and in this sequence – MUTE button, 1, 8, 2, and then the POWER button.
  • Step 2: When the SECRET MENU appears, use your ARROWS, SELECT, and RETURN buttons to navigate.
  • Step 3: While in the SECRET MENU Select OPTIONS
  • Step 5: Select BT AUDIO ON OFF and make sure it says ON.
  • Step 6: Use the RETURN button on your remote to go back a level on the SECRET MENU and select MRT OPTION.
  • Step 7: Select BT SUPPORT and make sure it says ON

Now TURN OFF of your TV and turn it ON again, give it a minute, select MENU on your remote control, then SOUND, then SPEAKER SETTINGS, and now you will see the BLUETOOTH Option!!!


    • We tried “Step 1” listed below the video and it worked. Step 1: While your TV set is turned off, press the following on your remote control quickly and in this sequence – MUTE button, 1, 8, 2, and then the POWER button.

  1. How do you know about these combinations ?
    As I have remote with Touch Pad and Voice control which even does not allow to press both of above Options.
    That means each remote and tv model has different combination to show Secret Menu.
    However when I press pairing remote with bluetooth which is working fine, then how come my headphone with blue tooth doesn’t work?

  2. I’ve done a walk through and done everything that was listed in order
    And when I got down to where it says
    Turn off the power then back on
    Select sound and then sound settings
    And wait about a minute and turned
    The tv back on I didn’t see A BLUETOOTH

    • We are unfamiliar with that Samsung TV model. The instructions are not for all Samsung TV models, just the one in the video.

    • Thank you for visiting ROKVU. Please note that this hack is not supported by all Samsung TVs. Please refer to the comments section of the actual Youtube video for additional help.

  3. Hi, My TV is Samsung UA55F6400. I went into the Secret menu and set both Engineer Option > BT AUDIO ON OFF = ON and MRT Option > BT Support = ON, but still no bluetooth speaker setting available in the TV Menu. Any other setting do I need to adjust? Thanks.

    • Hi HJ, sorry to hear about your frustration. Please note that this hack is not supported by all Samsung TVs please look at the comments of the YouTube video for additional help.

  4. I think i screwed up. The secret menu didn’t appear inmediately so i pressed the power button just before it appeared. Now the combination to access doesn’t work anymore. What can i do? I’ll appreciate any help. Thank you!

  5. Made the changes in the secret menu. Bluetooth address did show up under contact Samsung but it is :00:00:00:00:00:00. Still no Bluetooth under speaker settings. Any ideas?

      • I have the UN58MU6070 and bought it in Canada. Same issue, the secret menu worked and the speaker list is there but when I try to pair two different headphones it doesn’t pair. Do you know if there is anything I can do to make it work?

        • I am testing a new solution soon. It could be that your TV will only allow low powered BT devices like a keyboard, but not audio which requires a faster connection to keep up with the action on screen.

    • Sorry, all info available is in the video. You may also want to check the comment section of the actual YouTube video for additional information.

  6. HI, In many cases the Bluetooth Module in not installed. The secret menu shows no MAC Address for that. I did the configuration and the Audio menues are ON, and shows Bluetooth options, i can search for bluetooth speakers, but nothing happend…. just searching. If the bluetooth module in not instaled, you have no hardware to do the job. I have a UN43mu6100 series and i lived in argentina. I´ll try to buy a bluetooth module to install.
    Thanks for your help! I posted this to help someone

    • te recomiendo que busques en Aliexpress…me encargue un transmisor/receptor bluetooth con salida de audio óptico y me funciona de maravillas! solo 18 USD. Saludos desde Chile

    • I found that not all the menu options were visible. Select an option, then use the up/down options to go through all available settings. You will find some that are not otherwise visible in the main menu.

      Do this in both the Engineer and MRt menus. Make sure any BT options are enabled, also any sound mirroring or sharing.

      Once again, there are options that are only visible by scrolling through up/down. Not all options are visible in the main menu windows.

  7. hello
    I have a UN50MU6070FXZA and been trying to get the bluetooth to work
    and finally found the secert menu with (mute,1,8,2,power) and the option BT_AUDIO_ON_OFF -> ON…….now the secert menu won’t work at all and I can’t go back into with (mute,1,8,2,power) … you have any advice to get the secert menu to work again thankyou and have a nice day

  8. I am afraid to try this hack. Not one person on this tread was able to do the hack successfully. If there are people where this hack has worked on there 6290 it would be great to hear from you. From what I’m reading here, why chance screwing up your tv?

    • Unfortunately, the TV does have bluetooth which allows you to add a bluetooth keyboard, but not all Samsung TVs allow the pairing of Bluetooth headphones/speakers. Maybe if enough people complain, Samsung can unlock this feature through an update.

    • Unfortunately, it does not work on all TV models from Samsung. It is frustrating because you can add the Bluetooth option through the secret menu, but it will not recognize your bluetooth speaker or headphones.

  9. C’est exactement le problème que j’ai c.a.d. j’ai réussi par le menu SECRET d’activer le Bluetooth mais impossible d’appareiller des périphériques bluetooth.

  10. I have a problem after turning bt audio on in the secret menu .my samsung tv dont started every time restarted in 5 sec what can i do?

  11. Hello I have a Samsung samsung TV Mu6290 after doing the bluetooth option appears in the menu sound but it does not detect my speaker bose, I check in the secret menu and even if the support bt is a one in the tab bt adress on indicates not supported
    Thank you for your help

    • Unfortunately, this hack does not work for all Samsung TVs. You can try checking the Comments of the original YouTbe video to see if there is any additional support. Thank you.

    • Unfortunately, not all models do work. Please look at the comments of the actual YouTube video for additional support.

  12. I followed the instruction to the letter, to open the secret menu. However, there was still no blue-tooth option. Half hour later, still no blue-tooth option on my Samsung Smart TV. However, I have an Amazon Fire Stick, and I am able to connect my Blue-tooth headphones through that. But I can not use it with regular TV.

    • For a Series 6 640D you should get the secret menu. Not all TV’s have Bluetooth support for headphones through the secret menu, the Bluetooth is only for keyboard devices.

  13. Hi –

    Wondering if you can help.

    I have a 2019 Q Series Samsung.

    Bluetooth Headphones don’t connect.

    BT ON. Still doesn’t detect

    • We are seeing this a lot. The TV bluetooth seems to only work with a keyboard. Have you tried connecting a BT keyboard? Audio requires stronger BT.

  14. I can’t make it Bt adresses support ON
    I did even the upgrade BT but it Fail
    So still not support
    So any suggestions please
    I’ve Samsung série 7 55*

  15. Thank you! This worked and I am now able to use my headphones on all 3 of our Samsung tv’s.
    mute182power opened up the menus and was able to turn on both bt’s.
    Thanks again!!

    • You’re Welcome! Any lag in Bluetooth audio? Meaning does the audio match what is happening on the screen including lip-sync?

  16. This worked… Great.. I can see Bluetooth speaker now in my TV Output menu. But while searching Devices, it can not find any devices.
