5 Methods for Resolving a Black Screen on a Computer




Depending on the cause of the problem and the type of computer you have, repairing a computer with a black screen can be simple or difficult to complete. While some problems, such as loose cords, are extremely simple to fix, others, such as black screens on laptops, may necessitate the services of a professional technician. However, whatever the nature of your problem, here are five straightforward solutions:


Check Your Cords


If you are using a desktop computer, make sure that all of the cables that connect to the monitor are in good working order. The vast majority of monitors are delivered with two main cables and (possibly) a few additional cables for sound. Double-check the connections on both ends of each cord that isn't hardwired into your monitor to make sure they're secure. This will fix a large number of issues with black screens on the computer.


Ascertain That Your Computer Boots


If your computer does not boot, you will see a black screen, so ensure that the power button is fully pressed. This is true for both desktop computers and laptop computers.


After pressing the power button, listen to your computer and look at its LEDs to see what they are saying. Your computer's fans should begin to spin and make noise as soon as you turn it on. In most cases, you should be able to hear your magnetic hard drive spinning up Windows or Mac OS X when you first turn it on. The area where the cord connects to your computer may have lights, so check to see if any of them begin to blink if you are using wired networking (ethernet). If you have wireless, you should be able to see a light that indicates that the wireless adapter is operational.


If your computer does not show any of the signs of life listed above, it is likely that something is wrong with your computer rather than your monitor. Because laptop problems are so difficult to diagnose, you will almost certainly need to send your computer in for repair. A Power-On Self-Test (POST) code checker, which can be purchased on eBay for a few dollars, can be used to diagnose desktop problems.


Consider Using A Temporary Monitor


Please note that this is only applicable to desktop computers: borrow a computer monitor from a friend and ensure that it is compatible with your computer before purchasing one. As long as you're borrowing a monitor, you should also borrow the power and display cables from your friend's monitor (if they aren't hardwired in), so that you can test everything at the same time. If your friend's monitor and cords work with your computer, it is likely that one of your computer's components is faulty. Replace the faulty component after experimenting with various combinations of parts until you have identified the faulty component.


Consider Using An Install Disk


An operating system problem, such as an incompatible display driver, may cause some users to experience a black screen. During the initialization of your computer, your monitor will most likely function properly, but will then stop working.


Changing the driver will necessitate either booting into Safe Mode or reinstalling Windows if this occurs. It is important to confirm that this is indeed the problem before moving forward. Booting from a live CD, such as the Windows installation disc, or from a free Linux Live CD, such as Ubuntu, will allow you to confirm it. Nothing needs to be installed; simply run the disc until a desktop appears; if the desktop appears, you know that the black screen on your monitor is the result of a bad video driver; otherwise, run the disc until a desktop appears.


Use A Flashlight


Liquid Crystal Display (LCD) monitors are made up of two primary components: a Liquid Crystal Display (LCD) that generates images and a backlight that illuminates those images. Modern displays typically have a Light-Emitting Diode (LED) as their backlight, which should last thousands of hours but can occasionally fail prematurely due to overheating (especially if you have a laptop which you abuse).


The backlight of an LCD display can frequently be repaired if it is the only component that has failed, and while it is typically impossible to repair an LCD display for less than the cost of a new one, you (or a repair shop) can frequently repair it if it is the only component that has failed. So, how do you tell which is ineffective and which is not? Make use of a flashlight to illuminate the area.


Turn on your computer and monitor and wait for them to finish booting up completely before continuing. Once you've done that, use the brightest flashlight you can find and aim it at the monitor at an acute angle (to avoid direct contact with the glare). If you can see an image (such as your desktop), this indicates that the LCD display is still functional; if you cannot, this indicates that the backlight is broken, and your computer should be taken to a repair shop to be repaired.
