I have lost the display on my Acer Aspire 5338. It was ok one night but not the following day. I can see the display if I shine a bright table lamp onto the screen and except for the lack of light the computer is fine. I tried several restore points and have even used the back to factory settings without any difference. Can anyone tell me if I need to replace the screen? It is an HD LED screen with a gloss effect. Thanks!
