Last time was the thin green line on the LCD display, went back harvey norman to have a 1-to-1 exchange (14 days policy). After using it for 2 weeks, this problem appear and the image is the same as the one in this link and occur at any shutter speed. The shutter minor just got stuck when the button is pressed. Now have to go to nikon centre for this. My friend going to kill me for recommending her the D50...... :cry:
