As with most Laptop issues repairs to laptop screens is determined by a method of elimination. There are five major elements of a laptop's screen: the LCD screen or LED as well as the backlight, flexible cable, the inverter and motherboard. Sometimes, the root of the issue can be identified when the laptop's screen is fractured or cracked as a result of physical trauma. Sometimes, the cause of the issue isn't as obvious (as is the situation when the screen is dim). This article we'll explain the methods for troubleshooting the repair of a laptop's screen.
It is the first thing to ensure that it is the repair of a laptop's screen rather than a power issue or another laptop problem. This can be done by ensuring that the laptop is powered up correctly. If your display is in order and you observe your laptop booting into the bios and then into Windows It is then confirmed that the rest of your machine is working properly.
In the alternative, if your screen is cracked and all you can see is cracks, ink blots , and lines, then you'll be required to plug your laptop into an external monitor (a desktop monitor) and resolve the issue there. If the display you are using does not show a proper image of the boot-up process however you are able to hear the laptop being turned on correctly (normal beeps, fan spinning and spinning the hard drive) Then you'll be required to verify that the external display is working. If it's not, there is a motherboard issue that cannot be fixed through replacement of the screen.
After you have connected the laptop to an external display and verified that it is operating in a proper manner, it's time to pinpoint the root of the problem. If the display is dark or black, try using an LED to light up the screen at the upper left corner or in the center. If you are able to see the screen using your flashlight you are sure that the display is receiving the data correctly but it isn't lighting. This could be due to an inverter problem (test with a voltmeter in order to confirm the electrical output) or a backlight issue. If the inverter is defective it is necessary change it out with a fresh one. If the inverter works and it's functional, it's advised to replace your laptop's screen, instead of fixing the backlight. Repairing it is risky and requires expert knowledge.
If the laptop's display isn't dim, but there isn't a screen on it (but it is displayed on an external monitor) It is the right time to consider replacing the laptop's screen. Most laptop screen repairs occur caused by damage to the screens or the backlight. You may be faced with situations in which random dots begin appearing on your screen. horizontal or vertical lines are visible across the screen, or a discoloration that is growing of an area or a stain growing. In all of these instances it is necessary to compare the laptop screen against your external monitor. In the event that your external screen can not correct the issue it is recommended to replace the laptop's screen.
Repairing laptop screens is an extremely delicate process. Although it is possible to "do-it-yourself", keep in mind that you'll be dealing with fragile parts and plastics, as well as small screws, and the risk of further causing damage to the device and, ultimately, voiding your warranty. We strongly recommend using professionals for repairs to laptop screens since the difference in cost is often more than the peace of mind and warranty that comes with the repair.
