I had this happen too. I opened the display section by removing the small screws. I found that a capacitor between the output of the backlight inverter and the fluorescent tube had burned out and was loose in the case. The capacitor was a high-voltage type and was marked with its values. I found one at a specialty electronics store (retail stores like Radio Shack will definitely not have them). After I soldered the new cap in, the DVD screen worked fine. This is not a do-it-yourself repair like replacing a fuse. I only attempted it because I have experience repairing TVs. A competent television repairperson should be able to do this in a half hour. Of course, you might be experiencing a different issue, such as a burned-out fluorescent tube or dead inverter. That would require more parts and time to repair. I have heard of people using white PC case fluorescent tubes to replace burned-out backlights; not sure if that would be practical in such a small unit.
