I have the same problem as well,,,Photoframe was working and suddenly stopped....frozen logo on start-up....It did work for about two months then I found out from Samsung Support that this particular model was shipped with software that contained a worm.....downloaded new software and updated firmware.....this worked for about 12 hours and then froze up completely....I am going to return it and get another Photoframe(different model) or get my money back....very frustrating!!
