Do You Need a New Screen

The most fragile component of the laptop is the laptop's display.  Below are problems and possible solutions to check to see if you need a new laptop screen.  We can diagnose your screen issue for FREE and let you know what we find.

Dead Pixels

Dead Pixels are pixels on a LCD (Liquid Crystal Display) monitor that remains unlit or black.  Each pixel on an LCD screen is made from three separate sub-pixels: red, green and blue. When combined, its forms the colours that users see on the monitor. Dead pixels are rare and largely go unnoticed but if you have just bought a new laptop or monitor then you "may" be entitled to a replacement under warranty if you have more than 0.05% of dead pixels.

i.e For a typical laptop screen with XGA resolution (1024 x 768 pixels), there's a total of 2,359,296 red, green and blue pixels (1024 x 768 x 3). So a screen with 5 dead sub-pixels has a defective rate equal to 0.0002 percent.  Most manufacturers regard the monitor as being up to spec with up to nine dead pixels before they will offer a replacement screen / laptop.  

Dim Screen

This problem normally comes down to a broken backlight (cold-cathode fluorescent tube) or faulty inverter. If the back light has gone then you may have noticed a reddish or faded colours over the past few months or it looks like the monitor has to "warm up" before it gets fully bright.  If the inverter is malfunctioning then your screen won't light up the backlight leaving the monitor with a dim display. You may just about see a very feint image.

Cracked Screen

The LCD screen is one of the most vulnerable parts of the laptop - and probably the most common repair we do. It can be caused by dropping it, sitting on it or driving over it (yes, this happens!), flexing the screen when opening and closing (always close by holding the screen in the top centre) etc. 

Cracked notebook screens in general are not repairable and should be replace.

Lines On Your Screen

if your LCD screen exhibits vertical or horizontal lines then this could indicate a faulty LCD screen or faulty graphics card/chip.  To test if it is the screen or your display drivers / software is to connect your laptop to an external monitor. If the image appears ok on the external monitor then you have a faulty LCD screen which needs replacing.

Black Screen

The LCD screen does not have enough brightness or a black screen usually means you have a defective or dead backlight (CCFL) or inverter.  To test your fault is the screen and not your laptop (faulty battery, dead cpu, dead graphics cards etc) connect your laptop to an external monitor. If the image appears ok on the external monitor then the fault is your screen and needs investigating.  If the external monitor is also black or you dont have any activity coming from your laptop (no lights, no hard disk light flashing, no noise or fans etc) then the problem is more likely your laptop and not the screen.

Flickering Screen

Flickering can be the result of a broken cable from the motherboard to the inverter. This cable normally runs through the hinge and can get damaged due to twists when opening/closing the laptop.  It if it not the cable then it is likely the inverter is failing.
