My PDR-M500 was working perfect and then I looked down at a black LCD. I changed to electronic viewfinder and it was also black. All functions work, I can view old pictures on the LCD screen, it takes and stores "pictures" but they are black - almost like no light is getting in. I went to manual and changed settings but it doesn't make any difference. I upgraded to version 1.1 during all this and still no luck.
What would cause no light to enter the camera and the LCD or viewfinder remains black and therefore all pics or video are black - And yes, the lens cap is off.
