Compaq Presario CQ60 and CQ61 Laptop Screen Replacement

In this tutorial you will learn how to disassemble and replace a flickering or broken LCD screen on Compaq Presario CQ60 and CQ61 Laptop Notebooks. Compaq Presario CQ60 and CQ61 Laptop come with 15.6 widescreen. You will need to replace you defective LCD screen when you start noticing abnormalities like screen flickering, seeing lines on the screen or colours changing from green, pink and blue or sometimes when the screen backlight is no longer functioning.



Below I am outlining solutions to the laptop screen defects you may have;

Compaq Presario Screen Flickering

You have just opened your laptop and noticed that it keeps flickering when you move the top screen part up or down? This can be caused by two things. One, it could be the screen cable at the back of the LCD screen. This cable starts from the motherboard, passes through the laptop hinges and then is connected to the back of the screen. During the life of the laptop the screen cable could develop a problem at the hinges area because of the opening and closing of the laptop during use. The solution to this is to open up the laptop and replacing the cable.

The second problem could be the screen itself. With the use of the laptop mixed with carrying it about in bags or cases could result in the screen developing problems like flickering. The solution is simply replacing the screen as shown in this tutorial.

Compaq Presario Screen Showing lines and colours

If the screen defects you are having is the lining and colour problem then you will definitely need a new screen. Use the instruction guide here to acquire a brand new screen and replace the broken one.

Compaq Presario has lost its backlight

Your Compaq Presario laptop as you have noticed has no backlight but you can make out very faintly the windows running in the background. This can be caused by the laptop  inverter not working or the screen backlight has snapped after you have dropped the laptop. The laptop screen inverter provides power to the backlighting of the screen. The laptop backlight is a flat electronic board situated at the bottom of the screen.

The solution to the backlight issue is to first replace the laptop inverter and if doing this does not fix the issue the next thing is to replace the laptop screen.

Replacing the Laptop Screen

Now that you know what the problem might be. I will now show you how to dismantle and replace the broken screen or inverter of Compaq Presario CQ60 and CQ61 laptop.

Remove Compaq Laptop Battery

Before starting the screen replacement you must first remove the battery from the laptop. This is very important so as to avoid static charges damaging the laptop during screen removal and installation.

Remove Screw Covers

Use a flat screwdriver to remove the screwcovers covering the screws. There are two on both sides of the laptop. Keep these covers safely.

Compaq Screw Removal

One of the tricky part of this screen replacement is unscrewing the screws holding the bezel to the laptop. The bezel screws of Compaq Presario CQ60 and CQ61 laptops are slightly hard to remove as they are situated in the ackward area near the hinges. The best way is to place your screwdriver (use a precision screwdriver always) slightly vertical into the screw and by pressing down firmly start turning until you notice the movement of the screw. Do this on both sides and use the image as a guide. Click all images to enlarge.

Compaq Screen Bezel

Put your fingers between the plastic bezel and the compaq laptop screen and pull the bezel. Do this  on all sides to release it from the catches. Do this carefully to avoid snapping the bezel.

Pull Upwards To Remove Bezel

As shown in the picture on the right, to effectively carry out the bezel removal put your fingers into the space between the screen and the plastic bezel. Pull the plastic bezel upawards when doing this at the hinges area.

By removing the plastic bezel the internal part of the laptop is now revealed. On the top two sides of the screen you will find two screws as in the image on the left. Unscrew them and keep them safe.

Remove Camera Connection

If your Compaq laptop comes with a camera at the top this is the best time to disconnect the cable to the camera. Hold the camera module with one hand and use the other to disconnect the cable. Remember to reconnect it during the installation of a new screen.

Remove Side Screws

Cafefully Move the screen towards you a little and remove all side screws as shown in the pictures. Keep these screws seperately as they are different size from the rest of the screws.

Disconnect Ribbon Cable

After removing all the side screws place the screen face-down and peel up the clear tape holding down the screen cable connection. Remember to peel up the clear tape first before disconnecting the cable.

The next thing is to remove the inverter cable and always remember to connect the one from the screen you will be replacing the broken screen with.

At this point the screen replacement is complete.

This laptop screen replacement instruction can also be used for all Compaq Presario CQ61 and CQ60 laptop series including Compaq Presario CQ60-100EA, CQ60-111EM, CQ60-313SA, CQ60-214EM, CQ60-305SA, CQ60-100EM, CQ60-420SA, CQ60-212EM, CQ60-430SA, CQ60-107EF, CQ60-219EA, Compaq Presario CQ61-416SA, CQ61-402SA, CQ61-315SA, CQ61-310SA, CQ61-427SA, CQ61-110SA and many others.
