I would say there is a problem in the horizontal / high voltage section, but I have no information on this model.

Check your backlight settings, Power Settings, etc.....

You may have Vista (vista has other power settings such as a custom sleep mode which can fail sometimes to work properly with some hardware/monitor configurations).
So Disable any unconventional Hibrid Hibernation options k!

L13V36 Dark Screen, picture can be seen in bright light.


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

You probably have a problem with the back light inverters or the bulbs with this set. If you have no electronic background with working with TV sets, call in a pro to assist you in this repair. Good Luck

welcome to fixya

it sounds like the back light on both monitors are going bad
it might be better to call a repair man and get him to look at it see if it is going to be worth fixing i think it might be better then buying a new one at the prices now days

i hope this helps out have a nice day:)
