   If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

   If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

   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. See: http://www.microwavedisplay.com/doorsw.txt
   
   There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.
   
   At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes. See: http://www.microwavedisplay.com
