Powershot A460, LCD picture is black but display options appear

Hi, my Canon A460 was working fine and now the LCD view doesn't display anything besides the menu items around the edge (i.e. #picures, mode, etc). And when i take a picture in any light it wants to use the flash (which works) and the picture is all black. the LCD works on power up by displaying the blue "Canon" start so its not the LCD, can anyone tell me what I can do to get my camera taking photos again. Thanks.
