0 apm2.5 blue light only Posted by Quad Papa on December 8, 2012 at 1:31pm I had a pretty big crash. My APM board only shows blue light when connected to USB or battery. It will not reboot. Ideas??

Thomas, the reset switch seems to work. It will reboot, but the red light that shows armed never comes on. Other lights all work.
Thanks for the suggestions. I will post if I find a fracture. FYI it is the APM 2.5.
@Quad Papa,
Make sure that the reset switch is not stuck in the closed position.

You probably fractured a solder connection or solder trace on the pc board.
Do you have access to an inspection microscope?
You could inpsect the board carefully for fractures.
