In the following guide I show how to remove and replace the LCD screen on a HP G42 or Compaq Presario CQ42 laptop.
In this particular case I’m removing screen from a HP G42-303DX laptop.
In order to replace the LCD screen it’s necessary to separate the display panel from the laptop base first. Otherwise you will not be able to remove the screen bezel. Check out my first HP G42 and Compaq Presario CQ42 disassembly guide for the display panel removal instructions (steps 1-27).
OK, let’s assume the display pane has been removed and now we can start taking it apart.
As you see this laptop has a cracked screen. My target is replacing the damaged screen but I’ll do a few extra steps and show how to disassemble the entire laptop.
It’s not easy to replace the LCD screen on this HP laptop. In order to do so it’s necessary remove the laptop palmrest assembly (STEPS 1-19), separate the display panel from the laptop body (STEP 20-25) and only after that disassemble the display and replace the screen (STEP 33-48).
Also, I show how to remove the laptop motherboard and access the cooling fan (STEPS 26-32) but it’s not necessary to go though these steps in order to replace the screen.
