Dark LCD

I had the same problem. I called tech support had the guy helped me fix it. First turn the camera off and switch to movie mode. Then take the batteries and the memory card out. Hold the power button down for 3 seconds. Put the batteries back in and turn the camera on. (the camera should be working at this point) . Then switch the camera to auto mode and hold the "menu" button down for about 15 seconds. A screen should ask you if you want to reset the defalt settings. Hit yes and you are done. Hope this helps.

Is it possible that you've gone into M (manual) mode and the shutter speed is fast and a small aperture (large number) been selected? Or has the Exposure compensation been adjusted to be -2? Does it do the same thing in fully automatic mode? It certainly sounds like some setting has been adjusted incorrectly.

I have a sony cybershot dsc w730 , since a year. The problem is that over 2-3 months the LCD screen has become very dark. It is almost completely black unless I point the camera dirrectly at light. If I take a picture, the picture is exactly what the LCD screen looks like. It wasn't droped or anything. How can i resolve this problem. Let me know your solution
