Laptops frequently experience issues with their screens. Screen damage is common since laptops, unlike desktops, are constantly being transported. From identifying the problem to replacing the screen, you’ll find it all outlined in this post.
Making sure your laptop screen needs repair
We need to confirm that your laptop’s display is damaged beyond repair before we proceed with replacing it. Having accidentally fallen your laptop and noticed that the screen was blank, you may have immediately thought that the screen was broken. The screen could be somewhat broken, but it still might not be the problem. If your laptop has a VGA output, we’ll hook it up to a big screen to make sure the picture is crisp and clear. The graphics card or motherboard is likely broken if this is still not displaying. In this scenario, we recommend having these parts replaced. We only replace screens when we can view content on another monitor but not on your laptop. Additionally, we can notice that the image on your laptop screen is dim, or that the backlight is cycling on and off. Inverter failure could be to blame if this is indeed the case. If that’s the case, we’ll get in touch with you to propose replacing the inverter to see if the issue is resolved. Your laptop screen has to be replaced if we are unable to see any image on it, but the laptop itself displays OK on an external monitor.
Removing the screws to the laptop screen
After determining that the laptop screen needs to be replaced and receiving your approval to begin repairs, we will begin by disconnecting the AC adapter and battery. The next step is to inspect the screen’s frame for rubber tabs.
Once we locate these, we carefully pry open each lid with a flat-head screwdriver. There are multiple screws seen here that secure the “bezel” or screen frame. A tiny phillips-head screwdriver should be all that’s needed to remove these bezel screws. However, an allen screwdriver is used to disassemble laptops whose frames are held together by allen screws. Since we have the means to remove any type of screw, we can handle whatever wacky challenge the laptop’s manufacturer may throw at us. There may be no screws at all keeping the frame together. A small, flat tool can be inserted into a slit along the top and sides of the frame to pry it open.
Removing the frame
With the screws removed, we can take the LCD screen and its surrounding bezel apart. When the “pop” of the plastic snaps that hold the frame to the screen is heard, we know the laptop’s screen has been freed. After taking off the bezel, we can reveal the LCD screen contained within a second metal frame. This metal support is either mounted to the underside of the laptop, or resting against the case. By loosening further screws or by simply pulling them apart, we free the metal frame from the case. In order to remove the LCD screen and metal frame from the back casing, the remaining screws must be undone. Eventually, the LCD disconnects
from the screen but remains connected to the video line.
Checking the part number and finding a replacement
In most cases, we only need your laptop’s model number to obtain a replacement LCD screen. The LCD screen’s part number may be required in some instances. To check, we take the laptop’s LCD out and examine its back. Each component has a unique number and letter combination, like LP254WE2 or LTN156AT 19-001. To find the appropriate replacement screen, we require these data. Some people only want to use the manufacturer-approved LCD when replacing their panel. While others choose to save money by purchasing a third-party replacement LCD, there are pros and cons to either. Whatever one you choose, we will get it set up for you.
Replacing the laptop screen
Before we can swap out the display, we need to detach the ribbon video cable from the screen, which requires removing the tape. Then, carefully remove the plug. Another connection is connected to the inverter, a tiny circuit board. The liquid crystal display receives its electricity from this connection. Furthermore, we cut this cable. Once you’ve completed this final process, reassembling your laptop is all that’s left to do.what you should do If Windows Fails to Start
