Signs Of A Broken Laptop Screen
A broken laptop screen is quite a common sight for computer technicians nowadays with so many people wanting portability and the ease at which a laptop screen can be damaged. They do get a hard time and can be left on for prolonged periods of time and like anything else this can lead to failures like any other electronic component. At the end of the day a laptop screen is a complicated and delicate bit of equipment even though from the outside it does not look it.
The cost of repairs
When it comes to repairing a damaged laptop screen the cost can vary but tends to be over 100 in most places. This is mainly due to the cost of the screen as they can be expensive depending on the model to replace.
There are many signs that your laptop screen may be failing and apart from the obvious cracked screen we are going to look at 5 of them.
1. Laptop Screen Flickering
Is your laptop screen flickering? If so the chances are that your screen either needs to be replaced or you have a loose connection on one of the cables. There are 2 connections that can be causing your laptop screen flickering as a cable runs from the back of the screen to the main board in your computer. One end plugs into the motherboard of the laptop and the other plugs into the back of the screen. The cable tends to run where the hinge is so is susceptible to damage from opening and closing of the lid.
If you are comfortable taking the screen apart check both ends of this cable for loose connections and see if that resolves the laptop screen flickering problem.
2. A dim screen
A dim laptop screen can mean a number of things. Most laptop screens have 3 components.
- An inverter that regulates the voltage to the screen
- A CCFL Backlight Bulb which is what gives you the bright screen
- The actual screen
It could be any of these but if your screen is dim to the point where you can just see something on the screen if you catch it at the right angle than the chances are it is either the bulb or the inverter that is causing the laptop dim screen issue.
CCFL Backlight Bulbs can be picked up cheaply from places like Amazon but if you cant perform the screen repair yourself it is the labour that will be ultimately be expensive.
3. The screen itself getting hot or just above the keyboard getting hot
Most laptops have what is called an inverter that distributes power from the main board to the screen as the screen requires a different voltage. This is usually located either just above the keyboard or just below the visible screen behind the plastic. If this fails or is starting to fail it can get hot and is an indication that the inverter needs to be changed.
4. Vertical or Horizontal Lines on Laptop Screen
This is another very common cause of a faulty laptop screen that needs to be replaced. It is worth checking that the connections are properly plugged in as sometimes this can also cause horizontal lines on your laptop screen. In most cases though it is a case of replacing the whole screen.
5. Black Dots on Laptop Screen
This is usually a sign of dead pixels on a screen. A dead pixel is when the transistor that controls the amount of light fails. A dead pixel is quite rare and if it is only 1 or 2 dead pixels it is usually not too much of a problem. In rare occasions when there are multiple dead pixels your best bet is to replace the screen.
There are other reasons that the laptop screen may need replacing but these are 5 of the more common reasons. It is worth watching for the laptop screen flickering as this does seem to be the number one reason I come across for a failing laptop screen.
