Laptop LCD Screens: Troubleshooting and Diagnosing

By Edited Jun 4, 2015 0 0

A laptop's screen is by far the most delicate part, being that it can be broken with relative ease compared to other laptop parts.

And it's not much of a surprise; the LCD screen is the most vulnerable part as well, being on display 100% of the time the laptop is in use.

With that being said, it's not surprising that most hardware issues that consumers have is with their laptop's display. Whether it's a cracked surface, the brightness is malfunctioning, or even if the screen isn't responding at all. There are a number of ways a laptop screen could show signs of fault.

Let’s take a closer look into how these problems occur and what can be done to not only fix the issue, but to possibly prevent these mishaps from happening.

We’ll start with the most obvious of all cases to point out – a physically cracked screen. Most of the time when someone has cracked their display, it turns out to be the glass inside your screen. It will appear to show an ink blotch. This cannot be repaired. You’re going to have to replace the screen. Another scenario of consists of tiny, malfunctioning light bulbs being scattered along the display of the laptop. The official name for this is Dead Pixels. A variation of these, Stuck Pixels, are usually fixed by way of software solutions. These usually consist of different colors flashing throughout the screen in trying to “un-stick” the pixels. Although there are no confirmed ways to fix dead pixels, an uncommonly used tactic such as applying mild pressure to the afflicted areas in an attempt to return the faulty bulbs to normal may get the job done. However this method is not confirmed to work, so proceed in trying this at the risk of further damaging your screen.

If you find that your brightness isn’t as quality rich as before, you may be facing an underlying issue. You could be dealing with a Dim Screen. Firstly, make sure your brightness controls aren’t out of whack, and if they’re normal, you will need to further troubleshoot the issue. Seventy-five percent of the time, if the brightness of the display isn’t operating properly, the problem is with the inverter cable. I strongly suggest replacing the inverter cable before diagnosing the screen with the problem.

With these tools now wielded, you will be able to troubleshoot and diagnose your laptop’s screen if it ever begins to show signs of defectiveness.  And for those adventurous enough to want to explore the possibilities of DIY, here is a tutorial video to help you through the steps of removing your LCD Screen!
