i bought my digicam from ebay its an easyshare M753 yesterday at stonehenge, all of sudden my screen was black , the camera is fine except for that, the flash works andi can view my other photos i took, but when i turn it on, and get ready for a photo its just black, its new, i have only used it a few times.. i didnt drop it or anything, does anyone have any suggestions on how to fix this?the battery isnt low too.. it is a refurb model... thanks, amy
