    DSR7000 PS Trouble

    Last night my screen froze so I unplugged the unit and when I plugged it back in it started sparking under the PS. After taking it apart and pulling the PS I found a burn mark on the underside leg of the circuit board where the cord plugs into the PS. There isn't any solder on the connection, I don't know if it burned off or if there was very little in the first place and this is what caused the sparks. It was booting up fine (for the few seconds I left it plugged in) last night but throwing sparks .

    Should I try to re-solder the leg or buy a new PS ? Where would I find one ?

    Thanks for any insight you can give !

    Resolder it. It is recommended you unplug the power cord first.

    I'd say a cold solder joint, not enough solder, and poor manufacturing are what caused the problem (like some of those original Xbox PSUs). When the cold joint breaks under otherwise 'normal' stresses, it doesn't make a good (or sometimes not any) connection.

    The number of power supply related issues I've been hearing lately, including the chinese knockoff capacitors with the wrong electrolytes, combined with cutthroat cost-cutting by all the electronics makers makes me nervous about all the cheap electronic gadgets I've got plugged in around the house.
