    PLS help both Tuners A+B on my DM8000HD are dead - no signal at all, LNB is OK (tested with another receiver) Where is the source of 12/18V - 500mA for the LNB power? Any tuner schematic diagrams or DC voltage measurements or pictures? PLS HELP

    Normally, upon failure of the tuners is advisable to first install other, maybe older software before you think it's a hardware failure.
    If that doesn;t helps then replace the psu, or at least investigate.
    Because the 12/5 and 3v are important for proper operation.

    And maybe a little more information could help as
    Onboard tuners only failed.
    Or happens also with the extra tuners.
