One of the things that laptop manufactures have excelled in is the video.
When the plasma screen was introduced in the late 1980's laptops became real
laptops, the weight dropped form around eight pounds to a little over three
pounds. A real boon for laptop users.
Laptop repair requires extreme care and patience, this is a job you should
not rush. If you feel that you do not have the expertise you may want to take
the computer to a repair shop.
The case cover on the video screen should come apart the same as the computer
case. To get to the components inside the video case you do not have to remove
it from the main computer case. The removing the bezel around the screen will
give you access to the screen and the inverter module. A word of caution if you
have to remove the complete assembly: be very careful with the ribbon connector
and try to put the same amount of twists back in the cable when reinstalling the
assembly back on the main case. [Note: not enough or too many twists will tear
the ribbon cable when you open or close the video screen].
Once you have the bezel off you can then change out the component that has
failed. Reverse the disassembly to reassemble the repaired display.
One of the components that gets the most work or stress
are the video screen's hinges. With the constant opening and closing the hinges
will over time break. On newer computers more design emphasis has been given to
the hinges and the failure rate has dropped off but they are still a point of
failure. If you have a failure the best way to change the screen is to remove
the
keyboard to disconnect the ribbon cable and then remove the screws holding the
video display.
