    Duet won't boot - power issue?

    Hi my Duet suddenly won't boot anymore.

    I have measured the power supply it delivers 9 V.
    I can see a red light in the optical out socket - and sometimes the front led show a constant red.

    I felt that the power connection is a little wacky, therefore I disassembled the Duet and when measuring on the power connection on the backside of the PCB I only measure 5.20 V - is that normal?

    It's normal for a broken power supply, i e it can supply full voltage without load but it bogs down when it has to deliver any current.

    Just replace it.

    A bit late to the party, but I'd first change the power supply before getting into anything difficult. My Duet is now on its 3rd or 4th; my external HD that stores the music is on its 3rd; and so on and so on.....
