Hi hope some one can help?? I have an acer 8920, it been fine until the LCD screen has gone dark. The pc is working as i have a external monitor hooked up to it. I have been into screen resolution and all the setting are fine. I have tried FN to adjust the brightness, no joy there, however when I press FN + F6 the screen lights up for a half a second then goes out. I thought it maybe the inverter, so i changed that, still the same HELP!!!!
