So I was shooting Halloween Party yesterday with external flash and at some point I got 90% white shot with 10% on top of the frame good exposure. It was in the middle of the party and my heart sank at that moment. It was the best party I have ever seen. So I tried the usual tricks like powering down and all that. Nothing would help. Top LCD reads ERR. After fiddling around for a while I clicked the shutter again and again and I heard a click but no picture was taken. And camera started working again like nothing happened.
Wondering if it is an early sign of shutter failure. I will definitely drive to Nikon for a check up.
