My D3300 shows the “shutter error” and will not record any pictures and it will also not show any live feed. When I have it in manual mode, I can see the shutter flip easily with no issues and everything looks to be in place and mechanically working. Sometimes it will take a picture but it is just a fuzzy dark purple image (photo below). I know it’s a $300-$400 fix at my local camera shop and I don’t want to pay that, that’s more than the camera. Could it be that the shutter is moving too slow? Any advice?
