HP Compaq nc2400 LCD screen replacement

It's always gutting to see a laptop that's only two months old come back in with a smashed screen. Our suppliers quoted £255 for a replacement LCD panel plus £55 for fitting. Well, the part costs seem right to me but I thought I'd save the NHS £55 on labour by fitting it myself. It's a pretty simple operation that only takes half an hour or so.

For complete disassembly of the nc2400, see here.

As usual, the obligatory disclaimer:
Unless you're a dab-hand with a screwdriver, don't attempt any of this. Messing around inside your computer could cause damage and in certain cases can be hazardous to your health. This page is just a guide - you follow these instructions at your own risk. You should be careful handling the internals of a computer and follow antistatic precautions or you may cause damage. Also beware of the backlight circuitry involved with this procedure as you can get a zap from it. Remove the laptop battery and power supply before disassembly.

Step 1. Prise out the six rubber pads that surround the screen and use a T7 Torx screwdriver to remove the screws underneath.

Step 2. Using a small flat-blade screwdriver, carefully prise up the hinge surrounds on each side....

Step 3. ... and lift the touch sensitive panel out of the way.

Step 4. Using a small flat-blade screwdriver and starting from the top centre, prise the plastic screen surround from the LCD panel....

Step 5. ....Removing the lower part of the screen surround is tricky but it can be prised away using the ever trusty small flat-blade screwdriver.

Step 6. Remove the four Torx screws to release the LCD panel from the plastic laptop lid.

Step 7. Remove the four cross-slot screws from the sides of the LCD to release it from the hinged metal brackets.

Step 8. Disconnect the cathode backlight connector (beware of the circuit board this connector is plugged into, it has a transparent plastic layer to protect you but if you stick your fingers under it you may get a zap!) It's a bit awkward to disconnect but a pair of snipe nose pliers did the trick for me.

Step 9. Disconnect the signal connector. This is taped into place so you will have to remove or cut the tape.

Fitting a replacement LCD panel is simply the reversal of the procedure.
