In the following guide I explain how to remove and replace damaged LCD screen in HP G50/G60/G70 notebooks. I’m installing a new LCD screen into a HP G50 notebook but all disassembly steps should be almost the same or at least very similar for HP G60 and G70.
By the way, HP G50/G60/G70 notebooks also known as Compaq Presario CQ50, Presario CQ60 and Presario CQ70.
In most notebooks you can replace the LCD screen without separating the display panel from the base but not in HP G50/G60/G70. In order to replace LCD screen in these models we’ll have to remove the keyboard, keyboard cover and display panel. Let’s start replacing the screen.
Need spare parts for your HP laptop? Search by the part name or number here. You can find the HP spare part number in the service manual. I linked to service manuals at the end of this guide.
In the next post I explain how to remove laptop motherboard.
STEP 1.
Turn off the laptop and remove the battery.
Remove one screw securing the Wi-Fi cover and remove the cover.
It is not necessary to remove the memory and hard drive covers. I marked them just for your convenience.
STEP 2.
Remove three (yellow) screws securing the keyboard.
Remove four (red) screws securing the keyboard cover.
If you are using this guide for replacing the keyboard, you have to remove only three (yellow) screws.
In G50 and G60 the keyboard screws are located in the battery compartment.
In G70 notebooks there are only two screws securing the keyboard and they are located on the bottom (there is a small keyboard stamped close to each screw).
STEP 3.
Carefully lift up the keyboard from the base.
STEP 4.
Place the keyboard so you can access the cable connector underneath.
You have to unlock the connector and release the cable before removing the keyboard.
Move the white clip about 2-3 millimeters towards the display panel and release the cable. Now you can remove the keyboard.
WARNING! The white clip must stay attached to the connector base. If you accidentally break the connector, you’ll have to replace the motherboard. If you work slowly, everything should be fine.
On the picture below the keyboard connector is shown in the unlocked state.
STEP 5.
Disconnect the switch board cable from the motherboard.
STEP 6.
Remove the keyboard cover.
STEP 7.
Turn the laptop upside down and disconnect two antenna cables from the wireless card.
Each antenna cable has a golden head. Grab the head with your fingers and lift it up.
STEP 8.
Disconnect the video cable connector from the motherboard.
Disconnect the webcam cable from the motherboard.
Pull two Wi-Fi antenna cables through the opening.
STEP 9.
Remove four screws securing the display panel hinges.
STEP 10.
Lift up and separate the display panel from the laptop base.
In the following steps we will disassemble the display panel and remove the LCD screen.
STEP 11.
There are two screw seals located in the lower left and right corners.
Remove these seals with a sharp object and remove screws found under the seals.
STEP 12.
Start separating the screen bezel from the display cover.
Continue separating the bezel.
The screen bezel has been removed.
STEP 13.
The screen inverter board is mounted below the screen. The inverter is locked between plastic brackets.
You can remove and replace the inverter board without removing the LCD screen. Simply pull the inverter board from the cover and disconnect connectors on both ends.
STEP 14.
Remove two screws securing the right display hinge.
Remove the right hinge.
STEP 15.
Remove two screws securing the left display hinge.
Remove the left hinge.
STEP 16.
Remove the inverter board from the cover and disconnect one connector from the right side. By the way, this is the backlight lamp connector.
STEP 17.
Remove two screws securing the LCD screen on the top.
STEP 18.
Now you can separate the LCD screen from the display cover and access the video cable.
My HP G50 notebook didn’t have the webcam installed and the webcam cable was taped to the display cover.
If you have a HP G60/G70 notebook, most likely it came with the webcam. You’ll have to disconnect the cable from the webcam before disconnecting the video cable.
STEP 19.
Remove sticky tape securing the video cable connector and unplug cable from the LCD screen.
STEP 20.
Now you can remove the LCD screen from the cover.
If you are replacing the screen, you’ll have to transfer the left and right mounting brackets to the new screen.
Remove three screws securing the bracket and remove the bracket. Do the same with the other side.
The LCD screen model number is located on the sticker. In my laptop I had a screen with the following model number: B154EW08 v.1
The best way to find a new LCD screen for your laptop is either searching by the LCD model number (shown in the picture above) or using the HP part number.
The HP part numbers for LCD screen and other parts can be found in service manuals and here they are.
Service manual for HP G50 or Compaq Presario CQ50 (page 57).
Service manual for HP G60 or Compaq Presario CQ60 (page 4-23).
Service manual for HP G70 or Compaq Presario CQ70 (page 4-20).
After you find the spare part number for LCD screen or any other part, you can search for a new replacement part here. You’ll find many cheap LCD screen replacements.

kezy,
The laptop works with an external monitor, it means the motherboard/CPU/memory are OK.
Did you get any image on the undamaged part of the cracked LCD screen? Did you get the backlight?
For troubleshooting the problem you can try connecting the original cracked LCD screen back to the laptop to find out if the image is still there.
If you get image on the cracked screen but not the new screen, the new screen either defective or not compatible with your laptop.

the laptop fell from a table and the lcd cracked, so i had to get a new one lcd screen. but before doing that i hooked up the laptop via external cable tp know if it was working fine and it was, even used it for a couple of days before the new screen arrived, so yes i can get video when hooked up externaly to another monitor.

kezy,
If the screen is white, it’s not the inverter failure. That’s for sure.
Again, why did you replace the screen? What was wrong to start with?
Can you get video on the external monitor?

i replaced just the lcd screen, i also belive thats the problem but i checked it a couple of times and it still does not change, i was starting to think it was the inverter but am not sure, its there a specific way to place the video cable behind the lcd screen so that it can work,cos i think ive tried all i can.

kezy,
Why did you replace the screen?
Did you replace just the LCD screen or you replaced the whole display assembly (LCD screen, inverter, cable, plastic covers, etc…)?
Check connection between the video cable and LCD screen. Maybe the cable is not seated correctly.

For all those worrying about the power switch board cable – see the next article on this web site: “How to get access to the motherboard and substitute it.” which has a very clear photograph showing how it is unlocked. Perhaps Laptop Tech will edit this to include these photographs? Superb instructions very useful.

Would these same steps work for my hp dv4? I started out with the green/red line at the bottom of my screen, then a couple of days ago, the screen started flickering during the startup for about the first 5 minutes. HELP!
