Hi,
It an happen due to moisture, Temp solution unplug the cables and take it near a light to just give a mild heat and then reconnect.

Try and adjust the brightness to a higher level and see whether it helps.
Also try the contrast setting.

Good Luck!

try changing the display settings from the desktop just right click and select properties then change the display size and colors.

On the bottom of your monitor or on the right side is a set of buttons one is for brightness and contrast try to reset the brightness and then contrast. If this does not work you may need a new monitor.

The front panel switches are known to become leaky.You need to replace these switches.

If the backlight lights up for a second it's probably fine - It lay odds on the display inverter in the screen. Actually finding parts for anything made by gateway may be difficult, however. They do not sell spare parts. Considering the size of the LCD i bet it would almost exceed the replacement cost of the screen to repair it
