PostSubject: When The Backlight Of The LCD Screen Has Failed   Mon Nov 07, 2011 3:16 pm

Locate the battery-release latch and press down on it with one hand, and then pull the battery out of the case, setting the laptop battery aside.
The convenience provided by the portability of a laptop computer can
become a hindrance due to the screen malfunctions?it is not easy to
connect a new monitor as you can with a desktop system. If the backlight
of the LCD screen has failed, you can see any image. To fix the
problem, the entire inverter board and its connected LCD cable will need
to be manually replaced. Here below are the instruction for your
reference.
1.Check in the manual of your laptop or search the infomation from
the Internet to support the section of the manufacturer抯 websites. Just
get that what model fo inverter board you need for your computer, take
my Pavilion DV2000 Screen as instance, I purchase a right one from a reputable site, HooToo.com, and then i fix it by myself.
2.Turn off the laptop抯 operation system. Shut down the LCD screen
lid. CTurn the whole laptop over so the bottom end of the case is facing
up toward you. Locate the battery-release latch and press down on it
with one hand, and then pull the battery out of the case, setting the laptop battery aside.
3.Locate the rubber pieces on the edges and top of the LCD. Pop the
stopper pieces off of the case by inserting a flat object underneath
them and then pulling out toward you. Use a screwdriver to pull out the
screws hidden underneath the stoppers.
4. Put the laptop computer back over and open the LCD screen back up.
Slide a flat and thin object, such as a screwdriver, directly
underneath the seam of the plastic bezel underneath the LCD screen.
Wiggle the screwdriver up and down gently until the bezel pops off the
case. Lift the bezel up and check to see if there is a cable running to
the motherboard. Disconnect the cable if there is one.
5.Pull the case on the screen towards you, and then remove it from
the laptop. Locate the inverter board at the bottom of the screen and
find the cable running from the inverter board to the motherboard. Pull
off the strip of tape on the board and remove the screws holding it in
place if there are any on your particular model of laptop. Disconnect
the cable from the motherboard.
6.Connect the motherboard cable for plastic bezel and place the bezel
back onto the laptop case. Finally,just put the battery into the laptop
and power it on, and then once the manufacturer抯 logo appear on the
screen, it mean that you are successfull to install the new inverter
board and cable rightly.
