s905 - hdmi handshake /color space problem with older TVs

  • What "black screen" are you talking about? Please describe the problem further - it does not happen here.

    You might want to

    • change hdmi cable and tv hdmi socket to test for a bad connection
    • put a little pressure on the hdmi plug in your android box (with a small rubber band or some weight) - there are quite a few reports of badly soldered hdmi sockets
    • check the kodi settings for "adjust output frequency" and set them to "at stop/start" and add a time delay of 2-3 seconds so your old tv can catch up with the frequency change
  • Everything is working great now for several weeks :)

    But i have one issue,
    When i turn of Kodi 17 the X96 box is shutting down but also my Tv is shutting down.....
    Is there a fix or another way to prevent shutting down my tv

  • Please check the settings for cec, you find them in system-input, if I remember correctly.

  • U mean Cec setting in Android, i need to start te X96 box wihout the sd with LibreElec on it?
    Then cec off?

  • Thank you for the great solution!!

    I am so happy that I fixed my problem too, but I have a question.

    If I have 2 commands in my autostart.sh, how to separate them?I have a command to mount my NAS to my Android Box and another one to fix this issue.My autostar.sh looks like that, but I'am not sure that the second command is OK

     ( mount -t cifs -o username=root,password=libreelec,rw // /storage/recordings;
     echo 1 > /sys/class/amhdmitx/amhdmitx0/output_rgb
     ) &

    Thanks in advance.

  • hi everyone,

    i'm fighting against this problem (color space for old tv) since far, can anyone help me?

    i have a tv box with an s905x and i'm using libreELEC 8 on USB, can anyone tell me what should i do to apply the patch (or if there is a patch for veriosn 8). I never applied a patch on libreELEC nor in android so i need a little more help :)

  • Use LibreElec 8.1 and

     echo 1 > /sys/class/amhdmitx/amhdmitx0/output_rgb

    with your old Philips TV.

  • Well, I may have missed a step...

    # cat /sys/class/amhdmitx/amhdmitx0/dc_cap 
    # echo 'rgb,8bit' > /sys/class/amhdmitx/amhdmitx0/attr

    I'll do some more testing and will let you know.

    Edit : same issue after a few minutes.

  • Hello,

    which is the last version where:

    echo 1 > /sys/class/amhdmitx/amhdmitx0/output_rgb


    This one:

    I also have an old TV with a handshake problem.

    This version does not work anymore:
