The on camera fill flash pops up and works fine but, when you hit the button for it to go back down it doesn't. You have to manually set it back down into place. When I mount a hotshoe mount flash on the camera it won't fire. Earlier today the HS flash wouldn't fire when I hit the shutter button but afterwards it started firing off about 3 or 4 bursts of flash.
Any ideas on what is causing this?
