Do I need a new laptop screen?
Help Desk - Hints & Tips

Do I need a new laptop screen?It may be that your laptop has suffered an accident or possibly that you went to turn it on one day and the display wasn’t quite what it should be, in any event hopefully this article will let you know whether you need a new screen or not.

 

Cracked screen

The most common cause for this is that the laptop has been dropped or something has been dropped on to it, in this case yes it is best to replace the screen.  Consult Alien Technologies for more information and a quotation.

 

Stuck Pixels

A stuck pixel is a bright dot of colour most noticeable when the rest of the screen is black. Stuck pixels are fairly common on high resolution LCD screens. Stuck pixels sometimes start working again with time unless they appear black on a white background, these are known as dead pixels.

A software solution like http://www.jscreenfix.com/ can be used to “exercise” the pixel.  The software will flash a series of colours and intensities onto the section of the screen with the affected pixel in an attempt to unstick it.

Sometimes manual manipulation can be used to compress the layers of the panel forcing the oil within the panel to move however this method is not guaranteed to work and it may damage your screen permanently.

 

Black Screen

Try plugging an external monitor in to the VGA/HDMI output to see if the laptop is transmitting a picture at all.  If not then the problem lies with the laptop and not the laptop screen.  It the external monitor works fine then yes you would benefit from having a new screen or a new screen inverter, consult Alien Technologies for more information and a quotation.

 

Dim Screen

This can be caused by an incorrect setting in the power management settings of your laptop or a faulty screen inverter. Consult Alien Technologies for more information and a quotation

 

Lines

If your screen is permanently displaying horizontal or vertical lines this can be caused by a graphics setting on your computer or a fault in the screen.  To test, plug an external monitor in to the VGA or HDMI port, if the display works perfectly the problem lies with the laptop screen and yes it should be replaced if however the lines are still present on the external monitor then this problem may be able to be resolved by amending settings or reloading the graphics driver.  Consult Alien Technologies for more information.

 

Flickering Screen

Flickering can be caused by an incorrect setting in the display frequency/refresh rate setting or a loose/worn cable.  The cable that runs from the motherboard to the screen inverter can get damaged or twisted when opening/closing the laptop during normal operation.  Consult Alien Technologies for more information
