Cracked Screen? : Laptop Screen Replacement

As laptop manufacturers come out with slimmer sleeker designs by the year, the risk of accidental damage also increases and one of the most common victims is the laptop screen or LCD.

• Cracking of the physical LCD
• Black “ink” like blots on the LCD
• Discoloration
• Multiple dead pixels (more than 5)
• Flickering of the screen
• Afterimage

Doing a simple test by connecting your laptop to a working, external monitor and seeing if the issues stated above persists will tell you if the fault lies on the screen or other hardware like the GPU(Graphics Processing Unit) of your laptop.
If the external monitor works well, you can be almost sure that your screen/LCD is faulty.

You can easily damage the screen of a laptop without even realizing it.
In most cases, opening the lid of your laptop with too much force alone can cause uncesscary stress on your laptop screen and cause it to be damaged.
The most common causes for laptop screen damage are:

• Physical impact to the laptop screen or top cover.
• Pressure on the laptop’s LCD caused by improper handling.
• Placing heavy objects on top of the laptop.
• Opening of the laptop lid from the sides causing uneven amount of force which results in the screen bending.
• Power surge that can cause the screen to be shorted.
• Compromised hinge(s) which results in uneven pressure when opening and closing the laptop lid.

Majority of cases on laptop screen replacements stem from a faulty hinge that was ignored.
The hinge of a laptop is very closely related and often the root cause of LCD or laptop screen issues.
It is not advisable to only replace the LCD while ignoring hinge issues as the chance of your screen getting compromised again is significantly higher.

Even if the damage to the laptop screen seems minor like a few dead pixels or lines running across the screen, as time passes the damage will definitely spread and become worse with prolonged usage as every time you open the lid it stresses the already compromised screen even more and during operation, it is exposed to heat and electricity.

There is also a chance of completely shorting the screen or even worse, damaging your motherboard.

In some rare cases, the screen may even cause a small explosion and it is especially dangerous for models with a glass panel fitted in front as the glass shards will become deadly projectiles!
