I have a Nikon D7000 and a speed flash. I have use it before together and working find. I have not use it in over a year. Currently Nikon D7000 works and the speed flash. The flash does work. But when I take some picture not flash comes out of the flash. Can the bulb be out of the flash and needs replacing? If so any good videos showing how to change it? Little new to using the speed flash and camera.
Thank You,
John
