Hi Scott,
Really sorry to hear that.The key thing to check is the voltage on the +5V pin; use a multimeter to check the voltage between +5V and Ground (if you have OSPi 1.4, there is a +5V pin at the upper left corner of the PCB). If it’s between 4.9V and 5.1V, it should be fine.
You may also want to check the SD card — if the SD card is corrupted the RPi won’t boot. Re-burn the SD card image and see if that helps.
