My Minolta Dimage S404 has developed a wierd problem. When using the camera with the display screen turned on, it will give a low battery warning and shut off after about 2 pictures. this is on a fully charged set of batteries too. However if I use it with turning the display off I can get many pictures on the same set of batteries. Any ideas what it might cost to get it fixed? Is it worth it and any idea how long it normally takes?
