    Default DM500C repair anyone? No power/light

    Hi all,

    My DM500C server has croaked. First was no green/red light and was making a buzzing noise. Thought It may be the PSU and impatiently I plugged the dm500c into a Toshiba power supply ( I remember reading it somewhere )... Well the Toshiba psu sent a nice spark and she smoked up before I quickly unplugged it.

    I've taken a pic of the burnt bit of the board highlighted with the yellow box. Anyone can fix for a small fee? Or is it worth just buying a new one?

    Cheers

    Tsk tsk tsk! By the sound of it your Toshiba supply has incorrect polarity.

    The marked component is a power diode that's there to protect against reverse polarity. Provided it wasn't destroyed completely there's a reasonable chance your receiver may still be OK.

    I suggest you get a replacement DM500 supply (eg send Fernbay a PM, he has them for about $15). Give it a try. If you find the receiver no longer works then put it in the bin and buy a new receiver. Reverse voltage kills digital electronics devices very quickly.
