I've had a dsi for a few years now and when I turn it on, the. Lie light comes on but it's just a white and black screen and on the top there is something weird written down but the orange light comes on however the green light will not come on but if it does, I try clicking on something and a message comes up tell me to go to the manual. HELP PLEASE. I really need my DSI to work because I've got very important photos on there please help me
