If it went dead almost
immediately after pressing the Start pad, that's usually a shorted
high-voltage capacitor.
If it went dead
several seconds after pressing the Start pad, that's usually a
failing
high-voltage transformer.
Here are some links you
or someone you know can use (in order given) for test help, but read
the safety warnings first:

If
it goes dead or blows the breaker (or GFI) when you plug it in or open
or close
the door, then there's a problem with a door switch or door switch
mount.

If it's intermittent or
random, it may be a bad
connection, usually on the control board or a loose fuse holder, or
even an intermittent fuse.
