Question about Itronix GoBook III Notebook
Suggest you press the Fn key And the key to increase brightness, first. (Should be a key that has a sun icon on it)
Barring this does not increase the visibility of your LCD screen, the I suggest the Backlight is bad, or the Inverter.
The Backlight is a type of CCFL tube (Cold Cathode Fluorescent Lamp) mounted to the LCD screen. The LCD screen needs the light given off of the Backlight.
Replacing the Backlight is a daunting task, and if done wrong, will cause possible damage to the LCD screen.
The LCD screen itself has a thin metal frame holding the components of the LCD screen together. This frame must usually be opened on the side that has the backlight, to access the backlight. The components that make up an LCD screen are fragile, and can easily be damaged.
The Inverter supplies power to the LCD screen, as well as the Backlight.
Inverters do go bad, but commonly it's the Backlight to go first.
This shows a typical Backlight replacement. It IS not an advertisement to attempt this yourself, but a reference tool for information.
