    i received a DM 900 with "tuning problems". Quickly found 18V and 13V alt missing.
    On the Motherboard i'm missing 2 parts, the C118 and the BD106 next to EC107 / EC108 at the tuner connector (i can see - the way the soldering tabs look - they once must have been there).
    can you tell me the spec. of these parts - probably a 35V cap and a bidirection diode?
    thx

    The BD seems to me a inductor as also based on my voltages measurements it is.
    As for the values I have right now no idea, but maybe later I'm be able to see if I could measure it.

    Yes - its an L/C combination
    i simply relaced it with the L/C from a DM 800se 12V Tuner supply line ;-)
    and it's working OK
    as always - thanks a lot for your great info's!!
