   ASSuming you're working with a deskside and not a rackmount, the door 
switch may be the problem.  I've had 2 AS2100s fail to power on when the 
PCB in the LCD/switch panel became loose in its mounts.  It's mounted on 
4 split pins and the PCB wears and I think the pins lose their spring, 
so when you close the door it pushes the whole board aside instead of 
closing the switch.

   The fix was insanely difficult and technically challenging - I jammed 
the point of a plastic toothpick into the center of each of the split 
pins and cut it off flush.  :-)
