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

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

  • 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


    Shell-Script
    1. #!/bin/sh
    2.  ( mount -t cifs -o username=root,password=libreelec,rw //192.168.0.1/home /storage/recordings;
    3.  echo 1 > /sys/class/amhdmitx/amhdmitx0/output_rgb
    4.  ) &



    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 :)

  • As the note says: No, it does not work.

  • Use LibreElec 8.1 and

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

    with your old Philips TV.

  • I tested this build on a KDL-40BX400 Sony TV set, and got the pink/green screen a few minutes after booting :(

  • Well, I may have missed a step...


    Code
    1. # cat /sys/class/amhdmitx/amhdmitx0/dc_cap
    2. 444,8bit
    3. 422,8bit
    4. rgb,8bit
    5. # 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

    works?

    This one: 7.0.3.012?


    I also have an old TV with a handshake problem.

    This version does not work anymore:

    LibreELEC-S905.arm-8.2-8.1.10.img
