Answers :

I think you may have the computer's graphics settings set beyond what the LCD will handle, so it refuses to respond. With the monitor connected, change the desktop settings (size and refresh) lower and see if that gets you a screen once again. You can then reconfigure the settings to maximize for the LCD.

The screen on my packard bell laptop flickers. It is approx 1 year old. This happens if it has been on a while or has just powered up, when plugged in or running on battery regardless of what it is being used for (ie watching films, research etc).
