    Hdmi problems could be several things as,

    1. Software (drivers) related.
    2. Bad hdmi cable
    3. Tv hdmi connector, try it on another tv set.
    4. Bad hdmi connector. one bad pin connection or bad solder connection to the motherboard.
    5. Interrupted print track from hdmi to one of the ESD Protection Diodes (D600/D601/S602 srv05-4).
    6. Defective ESD Protection Diode.
    7. Worse scenario, interupted hdmi print track to the cpu.

    I have here a picture from the hdmi which may help,

    Hi, thank you very much for the topic and the diagrams.
    I bought a box 3 years ago and had always "green" screen by hdmi so I used only scart for about 3 years..
    Today I fixed the box, the problem was a factory bad soldering (short between pin 4 and ground):
