Change an LCD Bulb.
If you want to change a bulb or get the water out of an LCD you take a
chance of destroying the screen. You can take the screen apart but if its in
the lcd portion of the screen and not the plastic surrounding it, I would
have to say that damage is almost certain. You could look at it this way, if
you damage it you probably would have had to get another anyways so here's
how to do it. Each model and brand has a different way of getting certain
parts off of the laptop so I am going to give you the basics and if you pay
attention to what your doing you should be able to get the laptop apart
without damage. Unplug your laptop and remove the battery. You should remove
the strip of plastic between the keyboard and the LCD lid. Sometimes there's
screws that hold this to the computer and sometimes they don't. Once you
have the plastic trim removed you should be able to see the Video cable
going from the mainboard to the LCD lid. Unplug the cable from the
mainboard. If you have WIFI in your laptop there will be 2 wires that go to
the wifi card. You should be able to get the LCD out without unplugging
these wires and having to reroute the cables when you put it back together.
You will need some small Philips screwdrivers. Take the stick on tabs off of
the plastic bezel in the screen side of the LCD lid to reveal the bezel
screws. Take the screws out and carefully pull the bezel off. There are
normally tabs that keep the bezel on as well as the screws. Once the bezel
is off then you can get to the screws that hold the LCD in the back cover.
You will need to carefully remove the wires from the inverter (normally at
the bottom of the LCD) since you don't need to take the inverter off of the
LCD back cover most of the time. Once you have the LCD out you can take the
tiny screws out of the edges of the LCD. You also should unplug the Video
cable from the back of the LCD. Now the only thing holding the layers of the
LCD together is some tape. Sometimes its an aluminum tape. and sometimes not
but remove the tape from 3 sides leaving the side where the wires are taped.
Split the frame apart and you will find that you can get to the different
layers of display material. DO NOT PULL THEM OUT! Just lift the layers you
have to and wipe clean then blow with compressed air to remove dust. Any
dust may show when its put back together. Note: Be careful because the LCD
bulb is located in this area. This is the light that lights up the LCD. If
it breaks you will have to buy another LCD. Reverse the process to get the
LCD back together and see how it works. I have done what you are asking
about to change bad bulbs before. At least the LCD should look better and
the worst that could happen is you make the LCD not work and you have to go
to eBay and get another. Thanks...
Here are a few comments from people who were
helped.
It worked! I've spent almost two days trying to get
into my pc! I posted my issue on forums and tried MS KB to no avail. Thank
you so much! "Brad"
Man I hate having to fix my windows PC's and your
synopsis of how to replace config directories through recovery console
really did the trick. Thanks for making the internet a useful place.

wicket. Thank you!

Saved my A__ with this Dell 1505 laptop ~ I thought I'd
lost my whole hard drive but with your notes I was able to restore it to 4
days ago! Thanks! Good Job!
