Like many computer issues, a notebook screen fix is diagnosed by means of a process of elimination. There are 5 main elements to a notebook display: the notebook LCD or LED display itself, the backlight, the flex cable, the storage, as well as the motherboard. From time to time, the immediate cause of the problem is evident once the notebook screen has broken or cracked as a result of bodily injury.
Other instances, the origin of the challenge isn't too clear (as is the case once the display is dim). In the following guide, we'll cover the troubleshooting measures of a notebook screen repair.
The very first step is to affirm that we're handling a laptop screen repair rather than a power failure or other notebook issue. This is achieved by making certain the notebook is powering up correctly.
If the screen on your display is right and you'll be able to understand your notebook booting up through the bios and right into Windows, then you've established that the remaining portion of the machine appears to be functioning fine.
Alternately, if the display is broken and all you notice are cracks, ink blots, and traces, then you'll have to plug the notebook into an external screen (a desktop display) and purge from there.
In the event the external screen isn't showing a suitable display of this boot-up procedure however, you can listen to the notebook turning properly (ordinary beeps, fans rotation, hard disk spinning) then you need to confirm the external screen is operational. When it's, there's a motherboard issue which won't be solved by replacing the display.
