Hello. My display have suddenly stopped working. I use a sony NW-a1000. I can turn it on, and listen to music. But i cant see anything on the display. Its just dark, like it would be turn off. But the buttons have some light.. I really got no clue what to do..Could it be some wire inside that are sitting loose.. And if it got something to do with that, how do i open it. I understand it got something to do with that screw, but how to i screw it up.. Please help, asdw
