A little bit about laptop screen repair
Making sure your laptop screen needs repairBefore trying to replace your laptop screen, we have to first make sure that your screen actually needs repair. You may have dropped your laptop, and after seeing that it isn’t displaying an image, simply assumed that the screen must have broken. The screen might even be cracked a little, and yet that still might not be the reason you can’t get an image. If your laptop has a VGA output, we connect it to a desktop monitor or television to see if it shows the image correctly. If it still doesn’t show, it means that your graphics card or motherboard is probably damaged. If this is the case, we would suggest replacing these components. Only when we can see an image on an external monitor but not your laptop screen do we replace the screen. Another problem we may discover is that we may see a dull image on your laptop screen, or the backlight may flicker on and off. If this is the case, it is probably caused by a faulty inverter. If so, we contact you to suggest replacing the inverter and see if that fixes the problem. If we don’t see any image at all on your laptop screen, but the laptop displays fine on an external monitor, we know it’s time to replace the laptop screen.
Removing the screws to the laptop screenOnce we’ve decided that the laptop screen needs replacing, and you’ve given us the go-ahead to start working on it, the first thing we do is remove the power brick and battery. Next, we look for rubber tabs on the frame around the screen. After finding these, we use a flat-head screwdriver to gently pry open these covers one-by-one. These reveal several screws holding the “bezel” or screen-frame together. In most cases, we can unscrew these bezel screws using a small, phillips-head screwdriver. However, there are some laptops frames that are held together by allen screws, in which case we use an allen screwdriver instead. We have tools to remove every type of screw, so we’re ready for whatever weird puzzle the laptop designer throws at us. In some cases, there may be no screws holding the frame in place. In this case, we can open the frame by inserting a small, flat tool into a slit that runs along the top and sides of it.
Removing the frameOnce we’ve got the screws out, we pull apart the bezel and the LCD screen. In most laptops, the frame is secured to the screen with plastic snaps, so we know it has finally come out when we hear the “pop” of these snaps releasing. Once the bezel is removed, we see the LCD screen inside of another metal frame. This metal frame is resting against or attached to the back case of the laptop. We remove the metal frame from the case either by unscrewing more screws or by simply pulling them apart. Once we can get the LCD screen and metal frame away from the back case, we unscrew the rest of the screws that hold the metal frame to the screen. The LCD then comes loose, but is still attached to the video cable.
Checking the part number and finding a replacementUsually, we can order a replacement LCD screen using just the model number from your laptop. In some cases, we may need to know the part number of the LCD screen itself. If so, we look at the back of the LCD screen once we remove it from the laptop. The part number is a string of letters and numbers, such as LP254WE2 or LTN156AT 19-001. This is the information we need to find the right replacement screen. Some prefer to always replace their screen with the official LCD offered by the manufacturer. Others prefer to save money by using a replacement LCD provided by an independent manufacturer. Ultimately, it’s up to you which one you want us to install.
Replacing the laptop screenTo replace the screen, we first remove the tape holding the ribbon video cable to the screen. Then gently unplug the cable. There’s another cable running from a small circuit board, called the inverter. This cord is the power source for the LCD. We remove this cord as well. After finishing this last step, the only thing left to do is to reassemble your laptop.

Questions nerds often hear about Broken Laptop Screen Repair
Why is there no image?
There could be no image because your laptop screen is broken, your graphics processor is fried, or your motherboard is defective. Unfortunately, the only way to know for sure is to connect the laptop to an external monitor and see if the problem continues or not
My laptop screen shows an image, but it’s really dark. What’s going on?
You probably need a new inverter. The inverter converts low-voltage DC power to high-voltage AC power. This allows the screen to appear bright and crisp. If the inverter goes out, you’re not going to be able to read anything on it
Can you fix a broken laptop screen? Or do I need to buy a new laptop?
We can certainly fix a broken laptop screen by replacing it.
