How Do I Tell If My Laptop Screen is Broken?

Laptop displays are fragile and prone to damage, hence it’s crucial that you always enlist a professional to handle any fixes or replacements.

If your laptop screen is broken, there are a few telltale signs such as damage, dark spots and swollen areas that can indicate this.

Damaged Pixels

Your laptop screen is composed of thousands of tiny dots called pixels. Each pixel consists of three sub-pixels that cycle electronically to form the image displayed on your display. Occasionally, one of these sub-pixels becomes stuck in one color for some reason.

Stuck pixels can occur for various reasons, such as manufacturing defects or compatibility issues with certain software applications. Usually, they resolve themselves over time; however, if not, there are some steps you can take.

First, attempt to identify the cause of the issue. Doing this may allow you to determine if it’s something covered by your warranty.

If the issue is due to a manufacturing defect, you can bring it in for repair. However, if physical damage has caused the problem, you’ll have to replace your laptop screen.

One way to tell if damaged pixels are responsible for an issue is by checking how large they are. They usually look small, but can be noticeable if placed in a dark area of your screen.

Once you’ve eliminated a broken LCD screen, the next step is to inspect each pixel individually. The best way to do this is with a pixel test program which runs a cycle of solid colors so you can quickly spot any defective pixels.

Most of these programs also utilize flashing images to help you spot any issues on your screen. Be mindful, however; taking precautions could prove hazardous.

Another way to test a pixel is to wrap your index finger with microfiber and press gently on the problematic pixel. This method may help push the pixel back into alignment.

If this doesn’t work, you could try massaging a stuck pixel with some lotion. This could be an effective and safe method to restore light to a pixel that has become stuck in dark color.

If you’re still uncertain whether a pixel is to blame or not, give your laptop an extended break from usage for one or two days. While this could be risky, it might help the issue go away on its own.

Dark Spots

Black spots on your laptop screen may indicate an issue with the display. These can be caused by a variety of things, so it’s essential to determine what’s causing them before trying to resolve them.

Black spots on laptop screens are usually caused by dirt or dust accumulation on the screen. These can be quite annoying, so it’s best to clean it before using it again.

Another cause of dark spots on your screen may be backlight bleed. This occurs when some light from your computer’s backlight leaks through the edges, creating an uneven appearance. You can usually correct this by adjusting your display brightness settings.

If your laptop screen has several black spots, it could be time for a replacement. While you can purchase an appropriate replacement screen for your computer model, make sure that the one you buy is made specifically for that model.

You can test the screen to see if it has cracks or other signs of damage. A cracked screen is a big warning sign that something has gone wrong, and should be replaced right away.

Damaged LCD monitor screens can lead to dark spots due to broken liquid crystal tubes in the display. This repair is costly, and if not completed quickly, your display’s resolution may suffer significantly.

Unfortunately, this isn’t always the case. Sometimes black spots on a laptop screen may be caused by other issues like an outdated graphics card driver; you can try updating this driver to see if that helps resolve the problem.

You can try using a cleaning solution to eliminate black spots from your laptop screen. However, be sure to use a soft cloth as harsh cleaners may cause further harm.

Swollen Areas

Swelling is a common sign of various conditions, such as infections and allergies. In some instances, swelling may indicate that you should see your doctor; in others, however, it could just be an ordinary reaction to certain stimuli.

Swollen areas on your laptop screen may indicate that it’s time for an upgrade. This could be due to an impact or the device transitioning from hot to cold temperatures.

Another way to determine if your screen is damaged is by inspecting the backlight wires and connectors. If you are familiar with disassembling laptops, take out any case parts that cover these connections to inspect for damage.

If the cables appear to be broken or bent, they likely need replacing. In this instance, contact a repair shop or your manufacturer for assistance.

Swollen areas on your laptop screen could indicate that it needs replacing if they have cracked due to drops or falls from its stand.

You can also inspect the backlight for signs of damage, such as cracked or missing pixels. These are usually the most obvious indications that it’s time to replace your screen.

Signs of a broken screen include black or colored bars, colors that seem to run, and cracked glass. If any of these symptoms appear on your display, it’s likely your screen is broken and needs repair.

Swollen areas on your screen not only indicate that it’s time for a replacement, but they can also help pinpoint the source of the issue. Swelling is an often-occurring symptom that could be due to many reasons but is notoriously difficult to diagnose.

In some cases, your doctor can use a variety of tests to identify the source of swelling. This may include physical examination, bloodwork and imaging studies. Common causes include insect bites, fluid retention and autoimmune diseases; while diabetes or certain types of cancer can also lead to widespread swelling.


When your laptop screen appears to have cracks, be wary. These could be signs of physical damage or internal cracks causing issues. A cracked screen is a major problem and will likely need replacement.

When checking for cracks in tempered glass, the first type to look out for are those in the frame. These can be quite visible and give the illusion that your laptop screen has broken in several places, giving away that it has been damaged. This type of crack should always be taken seriously since this type of damage cannot be hidden easily.

Another type of crack you might observe on your laptop is those beneath the LCD panel. These are usually quite visible and can be identified by gently twisting the screen.

These can be caused by excessive pressure or force on the screen, such as when you drop it or close it a certain way. They could also be caused by objects hitting the display.

You might be able to tell that your screen has cracked by looking for other signs of damage, such as dark spots or ink splotches on the LCD panel. These usually indicate an impact to the screen that has damaged its backlight assembly.

One of the primary issues with a cracked screen is that it may lead to other issues with your laptop or its components. Repairing this can be expensive and leave your computer completely unusable.

If your laptop screen is damaged, it is essential to take it to a repair shop immediately. Doing this will guarantee the problem is solved properly and you don’t need to purchase another one later on.

Signs of an internally cracked screen include discoloration, issues with backlighting or resolution, pixelization and swollen areas. These could indicate that the internal glass has cracked, allowing liquid crystal to pool into certain regions on the display.

Cracks on laptops not only look unsightly, but they can be painful to touch as well. Therefore, it is recommended that you handle your laptop carefully and avoid touching it at all costs.
