The LCD screen on your computer is a simple display that gives you an idea of what's happening on your computer. It also provides a way for you to interact with various programs and files. If you're experiencing problems with your LCD monitor, it could be due to a number of things:
Does it have multiple colors in the display?
If you see multiple colors in the display, it could be a bad cable. The only way to know for sure is to take apart your computer and check that all of the wires are intact, which means if there's a problem with a wire then it will affect all of them equally.
If you can still see everything on your desktop as normal but have multiple colors in the display (and this happens even when playing games), then that might be caused by an inverter or something else related to how data gets transmitted from one part of the screen onto another part of it. It's likely not worth trying to fix this yourself unless money is no object; just buy new parts instead!
Does the screen display a black background with white horizontal lines, or gray with white vertical lines?
The lines are most likely caused by a bad video card. If you’re experiencing this issue, it will need to be replaced.
If the lines are caused by a bad HDMI cable, then you might not be able to fix them yourself without professional help.
Are there any missing pixels or areas of the screen where pixels are stuck on?
If you see a dead pixel, it is stuck on. If you see a pixel that changes color or flashes and stops, it is stuck on. If your computer's display looks dimmer than usual (or if it's even darker than normal), this may also be an indication that there are some dead pixels on your screen.
Are there colored dots or patterns on the screen?
If you see colored dots or patterns on the screen, it's likely that you have a problem with your LCD panel. If your monitor has a black background with white horizontal lines, it may be either inverter board or backlight problems.
If there are still no signs of life after disconnecting all cables and reseating the connectors in the monitor, then you should check for faulty connections between LCD and inverter board by removing them from their holders on both sides of their respective units while observing whether they move freely when pressed down lightly (if they don't move at all).
Is the entire screen lit up to one color (commonly pink, green, blue, black, or white)?
If the entire screen is lit up to one color, it's likely that the video card or inverter is damaged. The first thing you should do is check the cables and make sure they are plugged in properly. If you have a laptop, check that there isn't something wrong with your inverter as well.
If you have a desktop computer, check both your video card and power supply for any signs of damage.
Can you still see your desktop and everything on it as before, but it is just that your screen has darkened so you can barely see anything?
If you can see your desktop and everything on it, but it is just that your screen has darkened so you can barely see anything, then you probably have a backlight problem. This is a common problem with LCD monitors and can be repaired. If you have multiple colors in the display then you probably have a bad CCFL backlight and this can be repaired.
Did your computer get jarred while on and now your LCD monitor displays something similar to a really bad television signal?
If so, then you're probably looking for a way to fix it.
Check to see if the computer is still on and connected to a power source (this will help ensure that all components are working properly). If there seems like something wrong with this step, then try restarting your machine again by pressing the power button located on top of most laptops or desktops; however, if this doesn't work out just yet (or at all), then try checking other sources such as USB ports or even outlets near where they were plugged in originally. Additionally, make sure that none of these options have been disabled due either accidently or maliciously; if any have been disabled accidentally then re enable them immediately before proceeding further into repair steps below
What do I do if my LCD has a problem that I don't see listed above?
If your LCD has a problem that you don't see listed above, or if it's just not working as well as it used to, there are two options:
Call a professional. The cost of fixing your screen can vary greatly depending on the level of expertise required and the type and size of monitor involved.
Fix it yourself if possible. In most cases, this is best done with special tools available at an electronics store or online (or possibly even in the repair shop itself). Professional help may be warranted for major problems like cracked screens or bad pixels; however, minor issues such as dead pixels should be able to be resolved without too much trouble by following our guide below
