Like the majority of computer problems, a laptop screen repair is clinically diagnosed by a process of elimination. You will discover 5 major components to a laptop screen: the laptop FLAT SCREEN or LED screen itself, the backlight, the contract cable, the inverter and the motherboard. Sometimes, the immediate cause of the challenge is apparent when the laptop screen has cracked or broken due to physical trauma. Other times, the source of the condition is not so clear (as is the case when the screen is dim). In this post, we will cover the troubleshooting steps of a laptop screen repair.

The first step is to verify that we are dealing with a laptop screen repair and not a power failure or other laptop issue. This kind of is done by making sure the laptop is powering up properly. In the event that the display on your screen is proper and you could see your laptop boot-up through the bios and into Windows, then you have established that the rest of the machine appears to be working fine.
Otherwise, if the screen is broken and all you see are cracks, printer ink blots and contours, then you will need to plug the laptop into a display (a computer system screen) and troubleshoot from there. In the event the external screen is not showing a correct display of the boot-up process but you can hear the laptop turning on properly (normal beeps, fans spinning, hard drive spinning) then you will need to verify that the external keep an eye on is functional. If it is, there is a mother board issue that will not be fixed by replacing the display screen.
Now that you have plugged the laptop into an external display and seen that it is booting up properly, it is time to identify the key issue. If the screen is merely black or dark, use a torch to light up the screen around the top left corner or middle. If you can see the display by making use of the flashlight, then we all know the screen is acquiring data properly but isn’t light up. This will either be an inverter concern (test with voltmeter to confirm electrical output) or a backlight problem. If perhaps the inverter is bad, you will need to replace it with a brand new one. In the event that the inverter is useful, then it is highly recommended to replace the laptop screen rather than seeking to fix the backlight. That repair is unsafe and requires expertise.
If perhaps the laptop screen is not dim but you cannot find any display on the laptop (but there is on the external monitor), it is time to attempting replacing the laptop display. Most laptop screen fixes are due to a damaged screen or backlight. However, you may also experience situations where arbitrary dots start appearing on the screen, vertical or horizontal lines appear across the complete screen, a growing discoloration of an area is present of a sort of stain is developing. In all these cases, you will need to compare the laptop display to the exterior display. If the exterior screen does not reconstruct those issues, you should replace the laptop display.
