cloudy spot on dsc w5 screen

[ashish]

Hi I have this DSC W5, which I have been using well for 6 months. sudeenly a grey cloudy spot , about 2-3 mm on diameter has appeared on the screen. It is not visible when I focused on whilte sheet of paper in auto mode. But when i was photographing sunrise with shutter speed of 1\1000 ,in manual mode it became visible. It is more apparent when the camera is tilted . Any suggestions on this would be greatly appreciated.
