HDMI dosn't work

  • Hello dream-multimedia.
    Could you please help me, I have original dreambox 800hd se, it has been working for one year, but now something is happened with HDMI output,
    it doesn't work. But scart is ok.
    When I turn on dreambox booting is starting and HDMI works but while booting HDMI becomes unable and after booting only scart works.
    Something goes wrong while booting.


    On the mother board I see 3 red lights I think they are errors.


    Please explain me what I have to do?
    I can do all software stuff but I can't repair hardware.
    I have attached image with errors (red lights).
    Thank you.
