I just tried my a70 today, and noticed that I only get black. The menu function, whatever text like erase, set display all function, but the image does not come out on the LCD. The LCD is working, because when I hooked the camera to the pc, to upload the pics, all the pics were black. Like I'm not getting any picture through the camera. What is wrong? How to fix it? Bought it August 2003.
