    Hello Johnny!
    I have trouble with a DM820HD reciever.
    The HDMI output port is not working.
    Dreambox is booting up and on a small display is showing a channel and epg.
    I dont have video output. I've been changed the hdmi cable, tried on other TV, no sucess.
    Can you give me a hint to fix this problem?

    Sorry, but I do have not these box and thus cannot give any technical information about this receiver but suppose this would happen with a dm800se, then I would think on a cpu issue.

    But these are just some ideas of what I would try to do before thinking it's a hardware issue.
    Since the dm820hd has a Hdmi input and output it may related to the software you use.
    Maybe it helps if you use newer or other software, or maybe the Hdmi output may come back alive if you install the HDMI Input Plugin.
    Maybe it's just a wrong setting of the Hdmi settings and maybe it helps if you reset the box to fabrics settings.
    Or, maybe it's related to the power supply, probably not but it's at least worth to try with another one.

    In any case, allot of maybe's from my side, just because I have no experiences with this receiver.

    No sorry, I do not have any schematics and other technical information of the dm820hd.
    Because I never had this type of box, and never received it for repair.

    But still, if it's not due a software/driver issue, then it's most likely due a cpu issue assuming that the hdmi output port is connected/controlled directly to/from the cpu same as all the other type dreamboxes.
