What you need to know before you start
Replacing a computer screen depends on whether you have a desktop monitor or a laptop. Desktop monitors are straightforward—you unplug the old one and plug in the new one, usually in under five minutes. Laptop screens are harder: the panel sits behind the bezel (the plastic frame around the display), and you need to remove screws, disconnect a cable, and reassemble the frame. A laptop screen replacement takes 30 minutes to an hour if you have done it before, longer if you have not.
The cost difference is large. A replacement desktop monitor costs $80 to $400 depending on size and features. A replacement laptop screen panel costs $30 to $150, but if you pay a repair shop to install it, labour adds $50 to $150. Some laptops have screens glued in place, which makes professional replacement the safer choice.
Before you start, check your laptop's manual or search the model number plus "screen replacement" to see whether the job is straightforward or whether your specific model has quirks. Some laptops require you to remove the keyboard first; others have the screen accessible from the back. Knowing this before you buy parts saves time and frustration.
Key Takeaways
- Desktop monitor replacement means unplugging the old monitor and plugging in the new one—no tools required.
- Laptop screen replacement requires removing the bezel, disconnecting a cable, and unbolting the old panel, which takes 30 minutes to an hour.
- Laptop screens are inexpensive ($30–$150) but labour at a repair shop ($50–$150) can double the total cost.
- Check your laptop model's manual or a video guide before you buy parts, because some models require removing the keyboard or have screens glued in place.
Replacing a desktop monitor
Turn off your computer and unplug the monitor from the power outlet. Most monitors also have a cable that connects to your computer—this is usually a DisplayPort, HDMI, or USB-C cable depending on the monitor's age and your computer's ports. Unplug that cable from the back of the monitor and from your computer.
Remove the monitor from its stand or wall mount. If it is on a stand, you may need to press a release button or unscrew a bracket underneath. If it is wall-mounted, you will need a screwdriver to remove the mounting bracket. Keep the screws in a small container so you do not lose them.
Plug the new monitor into the power outlet and connect the display cable to your computer. Turn on both the monitor and the computer. Your computer should detect the new monitor automatically. If the image does not appear, restart your computer or check that the cable is fully seated in both ports.
Replacing a laptop screen: tools and preparation
You will need a small Phillips-head screwdriver, a plastic pry tool or old credit card, and the replacement screen panel. Do not use a metal screwdriver to pry the bezel—you can crack the plastic or scratch the frame. Plastic pry tools cost $3 to $8 at electronics stores or online.
Shut down your laptop completely and unplug the power cable. Let it sit for five minutes so any residual charge drains. This step matters: touching live circuits inside a laptop can damage components or hurt you. Close the lid and turn the laptop upside down so you can see the bottom panel.
Look for screws on the bottom panel that are near the edges of the screen area. Some laptops label these screws with a small icon of a monitor. Remove these screws and set them aside in a labeled container—they are often different sizes, and putting the wrong screw in the wrong hole can strip the threads. Take a photo of the screw locations with your phone before you remove them.
Removing the bezel and disconnecting the old screen
Flip the laptop right-side up and open the lid fully. Use your plastic pry tool to gently lift the bezel away from the frame, starting at a corner. Work slowly around the edges—the bezel is usually held in place by plastic clips, and forcing it can break them. You will hear small clicks as the clips release.
Once the bezel is free, you will see the screen panel held in place by a metal bracket on each side. Remove the screws holding these brackets. The screen will now tilt forward slightly, revealing a ribbon cable connected to the back of the panel. This cable carries the image signal from your laptop's motherboard to the screen.
Gently pull the ribbon cable straight out of its socket. The socket usually has a small latch or clip—lift it before you pull the cable, or you may tear the connector. Once the cable is free, remove the old screen panel completely.
Installing the new screen panel
Take the new screen panel out of its packaging and inspect it for damage. Place it in the same position as the old one, with the ribbon cable socket facing toward the motherboard. Insert the ribbon cable into the socket and press it down firmly until you hear or feel a click. If the socket has a latch, close it to find the cable.
Reinstall the metal brackets on each side of the screen and tighten the screws. Do not over-tighten—these screws are small and the holes are straightforward to strip. Hand-tight plus a quarter turn is usually enough. Carefully lower the bezel back into place, pressing around the edges until all the clips snap back in.
Reinstall the screws on the bottom panel, matching them to the locations you photographed. Close the lid and plug in the power cable. Turn on the laptop. The screen should light up when ready. If it does not, shut down, open the lid again, and check that the ribbon cable is fully seated in its socket.
Troubleshooting a blank screen after replacement
If the new screen does not display an image, the most common cause is a loose ribbon cable. Shut down the laptop, remove the bezel again, and reseat the cable by pulling it out and pushing it back in firmly. Make sure the latch is closed if your model has one.
If the screen still does not work, check that you did not accidentally disconnect a second cable. Some laptops have a separate cable for the backlight or for the camera. Look at the area where the old screen was connected and compare it to any cables you may have unplugged.
If you have tried reseating the cable twice and the screen remains blank, the new panel may be defective. Contact the seller for a replacement. Do not assume the panel is bad after only one attempt—most blank-screen problems are cable-related.
When to take your laptop to a repair shop
If your laptop manual says the screen is glued in place, or if you find glue around the edges when you open the bezel, stop and take the laptop to a repair shop. Removing a glued screen requires heat tools and can damage the frame if done incorrectly. The labour cost ($50–$150) is worth avoiding a cracked chassis.
If your laptop requires removing the keyboard to access the screen, and you have never done this before, consider having a professional do it. Keyboards are held in by clips and screws in different places depending on the model, and breaking a clip means replacing the entire keyboard ($80–$200).
If you are uncomfortable working inside electronics, or if you have already tried the steps above and the screen still does not work, a repair shop can diagnose the problem and complete the replacement. Most shops charge $100 to $250 total for a laptop screen replacement, including parts and labour.
Frequently Asked Questions
Can I replace a laptop screen myself if I have never done it before?
Yes, if your model does not have a glued screen or require keyboard removal. Watch a video of someone replacing your exact laptop model first—search "[your laptop model] screen replacement" on YouTube. If the video shows the process taking under 20 minutes and looks straightforward, you can likely do it. If it looks complicated or involves heat tools, take it to a shop.
What if I drop the new screen panel before I install it?
Laptop screen panels are fragile. If you drop it and see cracks, do not install it—a cracked panel will not display an image and will not get better. Contact the seller when ready for a replacement. If the panel looks fine after a drop, inspect it under bright light for hairline cracks before you install it.
Do I need to buy the exact same screen model as the original?
Usually yes. The connector type, resolution, and physical size must match your laptop's specifications. Search your laptop model number plus "screen replacement" to find compatible panels. Buying from the original manufacturer or a reputable electronics seller reduces the risk of getting an incompatible panel.
Will replacing the screen void my warranty?
If your laptop is still under warranty, opening it yourself may void the warranty. Check your warranty terms before you start. If the screen failure is a manufacturing defect, the manufacturer may replace it for free under warranty. If you open the laptop first, they may refuse to cover it.
How long does a replacement screen last?
A replacement screen panel lasts as long as the original—typically five to seven years for a laptop. Lifespan depends on how often you use the laptop and whether you expose it to heat or moisture. A desktop monitor usually lasts seven to ten years.
