NOTE THAT WE ARE PUTING THIS REPLACEMENT INSTRUCTION HERE AS IT IS THE FASTEST WAY TO REPLACE THE SCREEN. THERE ARE OTHER SLOWER WAY WHICH REQUIRES DISMANTLING THE WHOLE LAPTOP. LOOK AT THE WHOLE INSTRUCTION FIRST BEFORE STARTING. I suggest considering laptop screen repair service if you feel unconfortable doing it yourself.

Compaq Presario laptops part numbers may have suffixes after the model numbers. Please note that this does not affect the screen type in the laptop as they all come with the same types of screens. These numbers can be found at the bottom(under) of the laptop.

Compaq Laptop Battery









Remove the Compaq laptop battery  before starting the replacement. Removing the battery is essential as failure to do so may cause the laptop backlight or any other part to malfunction after the replacement.





Compaq Presario CQ56 Bezel





Compaq presario CQ56 and the CQ62 do not come with any screws on the outside plastic bezel. So simply use a flat object or put your fingers between the laptop screen and the plastic bezel and start pulling on all sides. Doing this will let out clicking sound which comes from the catches around the bezel releasing.






NOW ONE OF THE MOST IMPORTANT PART! Because this replacement will be done while the plastic bezel is still on, put your fingers in the line space at the lower part of the screen and the bezel and pull that area towards you to expose the screen cable.











At the top part of the screen remove the screws on each sides holding the hinges arms to the back cover.




Remove Side Screws







Now carefully pull the screen towards you slowly and remove the side screws. NOTE THAT DOING THIS WILL PUT A BIT OF STRAIN ON THE PLASTIC BEZEL AND BY BENDING TOO MUCH WILL SNAP THE BEZEL.









At the lower area you will need to remove the side screws as well but there is only a limited space to do this as pulling too hard WILL snap the bezel. The trick is to put something at the bck of the screen as we have done in the picture.










At this point you will be able to almost see the whole back of the LED screen and the cable connection.




Free the Screen Cable







The next thing to do is to start freeing the screen cable in the middle of the laptop. The reason for this is for the screen to easily come away without the cable faulting.












Using the image on the right as a guide use the flat screwdriver to raise the cables away from holders.









Now that the cable is free take the screen out carefully will the cable at the back of the screen is still connected. NOTE THAT THE SIDE OF THE LAPTOP MUST BE AT THE EDGE OF YOUR TABLE TO ALLOW A SUCCESSFUL REMOVAL. LOOK AT THE IMAGE ON THE LEFT.










Place the screen carefully face-down on the table. Note that at this point the cable is still connected to the screen so do not pull at all.









It is now safe to remove the screen cable connection. This connection is held down with clear tape by the laptop manufacturer. With the aid of a flat screwdriver or with your fingernail peel up the clear tape.









IT IS NOW SAFE TO PULL THE CABLE AWAY FROM THE CONNECTION. Pull the cable away from the screen. Be careful as some of the screens have strong adhesive. The Compaq CQ56 and CQ62 cables are very fragile so carry this out with care.






The screen removal process is now complete. Carry out the process in reverse order to fit a new screen.
