  • DM920 red led (after thunderstrike on tuner)

    Hi who is saying that the dm920 or power supply is not working. i guess but i say guess my problem is laying arround the tuner part ... but that has been removed for now to get the box powered on. i am curious to the buck convertor power supplies in standby. if any help ? please let me know...

    the 2x 3 red in circled buck convertors outputs who can help me to tell what the output voltage should be for each ?

    - in standby

    - in running mode

  • DM920 red led (after thunderstrike on tuner)

    Hi i have a DM920 which stays with a red led after last weekend lightning. lots of houses in the neighbourhood had RF issues with equiptment. so now i want to start a reverse engineering project about the dm920 here.


    the first one is does the DM920 (or DM900) power up/ boot up without a tuner installed in the unit? or does the power led stay red....


    from here i want to post pictures from the board and some voltage points measured in a good unit.
