My pop-up flash on Nikon D5000 used to work well in manual & aperture mode meaning - the shutter speed would increase automatically when flash was popped out.
Recently, I put an external flash - Achiever 828 & started clicking & before putting it on, I had checked if the flash was supported (trigger voltage) & on one of the forums it said, it would.
I put the external flash & took some pictures. Now, when I pop-out the camera flash (not using the external flash), it doesn't increase the shutter speed at all! I probably feel it is due to the external flash & could have damaged the circuitry.
Appreciate if someone could help me on this. I m planning to take it to a service shop soon enough but before then any help is very much appreciated.
