Question about Computers & Internet
Heidib92 your Inverter is bad, or the Backlight. (Freeze Mode? lol)
An LCD screen cannot produce enough light by itself. It needs an external light source.
A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp
There are examples of these in residential, and commercial applications.
The Fluorescent lamps you see on the ceiling. (Schools, businesses, banks, etc)
A Backlight is located generally on the edge of the LCD screen.
(An LCD screen is a composite of layers. The outside layer that faces you is a protective screen)
An Inverter is used to change the electrical source leading to the LCD screen, and Backlight, from the laptop.
A laptop cannot produce enough electrical power to power an LCD screen. It also provides power to the Backlight.
Here are examples of replacing a Backlight in a laptop, and an Inverter,
What is the manufacturer name , and Model Number of your laptop? It's on the Bottom of the laptop. This way I might be able to provide more than just the generic info above.
