Half Of My Laptop Screen Is Glitched Out

Why is my laptop screen half black? How can I fix it?

ALL of these people are correct.  I work for Dell as a field technician.  It’s already been said, but I’ll repeat it for emphasis:First, hook up an external monitor.  If the display is good, then the graphics chip is fine… and that’s probably good news, because on most (not all) laptops, you’d have to replace the motherboard, which will not be cheap.  If a motherboard needs replacing, expect to spend $100 plus labor, unless the laptop is an extremely common model (such as the Dell Latitude D500 series, which was purchased by a lot of schools).However, something which has not been said, is that it doesn’t necessarily mean that the motherboard is good.  There is a ribbon cable that connects the LCD to a connector on the motherboard.  It is possible for the connector itself to fail.  In 15 years of working for Dell, I’ve seen it happen once.  Though if it fails, usually nothing displays at all.In any case, if everything shows up on the external monitor, the most likely culprit is that either the LCD has cracked, or the ribbon cable has failed.  A specialist might have a replacement LCD on hand, or at least one that he can use temporarily to determine if the cable is bad.

My laptop turns on but the screen is black. What do I do to fix it?

Other answers have jumped to a hardware fault. Perhaps not incorrectly, sure. But I'd first make sure we're not dealing with a software issue, or any other "have you tried turning it off and back on again?" sort of things.First, and foremost, does your laptop have a "Display Off" button? I have a Sony Vaio which has one of these. It's a flush bezel button near the clamshell hinge. I have absolutely no fucking clue why it's there. But it is. The only thing I can think of is it's a "privacy" button...for when you can't quite hit the (x) close button on the browser window when your spouse walks in on you ogling (.)'s.Since you didn't post a picture I will assume that you mean the screen is entirely black. No faint glow, no nothing? In other words, it doesn't look even remotely like this [note the blinking cursor]:Have you plugged anything new into your laptop recently? A new USB device? A new external drive? Do you have a docking station? If you have a docking station, does it behave differently if on or off of it?Have you verified that your battery is charged, and that even if not, your power supply is providing proper charging to the battery when it's plugged in? My laptop has a little lightning-bolt LED that indicates the power supply is properly plugged in. Sometimes those stupid connectors can become loose -- or worse, crimped [kids knocking the thing about, etc.] -- so that they don't make a proper connection. I can't tell you how many times I've sat down with my laptop that had been "plugged in" for hours only to hit the power button, see it appear to go through its start-up groans, only to have it fizzle-out and not work shortly after.Do you have a recovery disc for the OS you have installed? What happens if you turn the power on with that in the laptop?Do you have a USB memory stick? If so, there are a bunch of different things to try here Boot and run Linux from a USB flash memory stick, even booting DOS from it.

Green lines are appearing on a laptop screen. What is the problem? How can I resolve it?

The image which we see on our screen is a result of many tiny pixels that creates a perfect blend of colors to generate it. Every single pixel in the display is made of three subpixels which are red, green, and blue. Small transistors inside the screen electronically trigger the correct color which collectively displays a picture. When these pixels stuck on a particular tone, then it will appear as a single dot on the screen whereas if the number of stuck pixels is high then, it will surface like a green line on a laptop screen. Now, before deciding to replace your laptop screen you can try some methods which can help you in resolving this issue on your own.· Ensure the source of a problemTwo components can be responsible for green lines which are LCD screen and the graphics card. Each part has a different process of repair. To find the source, first, try a different monitor to check whether the lines appear on a new display. If they do, then the graphics card has malfunctioned. Second, examine display settings and alter them if they are not ideally set. If both the things are not at fault then probably the issue is with a display.· Pixel pressure methodStuck pixels can get back to normal operation by applying gentle pressure. Here you can use a piece of tape to highlight the area where a green line on laptop screen has appeared. Now with a soft cloth, you have to employ moderate pressure to the stuck pixel line after turning the system off. Make sure that you don't press it hard otherwise the problem will get worse. It will tenderly flex the screen material which will make the pixels to shift from permanent “on” position hence resolving the issue.· Update the driversOutdated drivers can also lead you to a green line on a laptop screen. Here you have to check the driver versions for graphics card and LCD. If there are updates available, then download it and keep your OS updated as well.· Color cyclingQuick cycling of the colors can fix stuck pixels. It helps in removing "kinks” out of the subpixels which brings them back to normal condition. You can do this with the help of programs which are available online as free downloads such as Jscreen Fix, Undead Pixel etc. The process can take up to 20 minutes to an hour, but it will fix the issue.In case if the problem persists, then it will be wise to contact a repair service provider as an expert can lead you in the right direction if you can't find a solution.
