My flash has stopped working. Any ideas?
@mainelysteele there is no way to say for sure which part may have failed. This could be an error on the PCB (blown fuse) as well as a bad flashing unit or a bad capacitor. It’s time to take it apart and to check things out. I would suggest you download ==» D3100 SM this document. Disassemble your camera and let us know what you find.
