The shutter of my G3 occasionally get stuck. That is, sometimes, right after a shot is taken, the LCD goes black as if I put the lens cap on. However, indicators like mode, ISO, WB, and etc are all on. So it is different from LCD going blank. If I turn the camera off and turn back on, the camera works fine again. This happens about 1 out of 30 times.
Does anyone have any idea what is wrong and possible how to fix this problem?
Or is this normal (like occasional computer freeze...)?
Thanks.
