This is a guide to show you how to remove a laptop LCD screen on a Compaq Presario. For tools we will only need 2 tools: a phillips head screw driver and also a sharp/pointy knife.
We will first lift up the lcd screen so that the notebook is in an open state. Look for 6 rubber casings very small circles. They cover 6 screws that we need to remove on the frame of the lcd screen. Use our pointy knife to lift these rubber coverings up. Put them off to the side in a safe place. Take our phillips screw driver and make sure it is small enough to fit in the 6 holes. Remove the 6 screws and put them with the rubber coverings we removed in the last step. Lets take off the outer frame that was being held on by those 6 screws. Be very cautious not to go ripping at the frame, and just take it off gently and do it little by little all the way around. When it starts to feel loose you know you are doing it right. Now that the frame is off we need to identify a few things. Start with the 2 hinges at the base of the laptop lcd screen that we are going to remove. Next look at the left hinge there is group of wires 1 inch thick, that is the video cable that plugs into the motherboard. To the right of that is 2 wires together, that is the inverter wires. The inverter wires run right to left along the base of the LCD screen. Next lets free the LCD screen from the back cover, since the front frame is removed just do the back now. 2 screws secure it to the notebook screen. These 2 screws are on the sides and towards the top. Fold the lcd screen down towards the keyboard a little and begin unscrewing those 2 screws, to free it from the back cover. Detach the cables we talked about before now, the video cable and the inverter cable. They are attached to the actual motherboard of the Compaq Presario motherboard. The video cable might have a little bit of tape holding it down, remove that, then unplug it from its connection. The inverter cables will be easier to detach here.
