More about : lcd troubleshooting Anonymous December 12, 2009 3:33:02 AM Probably the backlight. Try shining a torch at the screen while it's running and see if any image visible. Backlight problem is either power supply or fluorescent tubes/circuitry. Of course, start by checking that no-one has selected an impossible combination of contrast and brightness. Access the on-screen display controls and select reset to defaults. cbaugusta December 19, 2009 8:01:47 PM Thanks, Can't find your answer ? Ask !
