I search the term 'flash' for all 13 resulting pages before posting and did not find an answer. Short version: the on camera flash has all of a sudden stopped working. It is in the popped-up position, and the result is the same under any shooting mode (P,A,M). On each mode with the flash popped-up, the icon appears on the lcd screen indicating flash is disabled (circle with line through it). I've gone through the menu into the flash settings and toggled the available setting with no luck. Any ideas what may be causing this? Does it have to go in for service?
