How can you fix flickering lines on a laptop's screen?
Unfortunately flickering lines on your screen is very rarely a good sign.The first thing I would try would be to check for an updated graphics driver but unfortunately I feel it is likely to be more complex and more than likely one of the following:The screen is failing and needs to be repaired - Screens do fail it is one of the more common parts I replace Cost could be anywhere from 50 - 100 depending on the screen.The inverter is failing. The inverter in most laptops regulates the voltage to the screen. Usually the screen just goes black or very faded but it can cause lines before it gets to this stage Cost 30–50The cable that runs from the motherbaord to the screen is faulty - The cable usually runs up by the hinge and get get kinked and damaged. Theya re relativly easy to repalce but do require you dissasembling the screen - Cost 35- 60The graphics chip on the board is failing. Most laptops have a graphics chip soldered to the motherboard. These can fail and there was a stage where certain laptops were becoming de-soldered from the board causing these kinds of problems. If you connect the laptop to an external display and dont have the lines you can pretty much rule this “Terminal” diagnosis out. Cost - Likely uneconomical to repairEither way you best bet is to take it to a local repair shop and get them to have a look for you.Good Luck
What is the cause of a flickering laptop screen?
You should be specific and state under what conditions this is happening. For all we know you are seeing flickering in a camera recording of your screen. Is it accompanied by discolorations which come and go? That would indicate a loose connection. Is your laptop an HP? If so you’re probably in luck, and can go to HP for instructions in how to access the connector, or even replace the LCD.Other than that, check your refresh rates (what one guy called vertical frequency), change to native resolution, that sort of thing. Turn off ambient light to see if you’re getting interference.
Why is my laptop screen flickering after I accidentally dropped it to the floor?
If you are comfortable doing it, I would pop it open and look at the connections to your screen. It is possible you jarred something that either needs to be plugged in more securely or touched up with a bit of solder. Superglue can also work, and, in a pinch, I have secured loose connections with clear coat nail polish. Just be sure any solvents have dried before powering up in the off chance a spark will ignite them.
What should I do if my laptop screen flickers when it heats up?

Laptop screen flickering and it's making a whistling noise. What could be wrong?
You need to quit picking it up by the screen and/or slinging it around. As far as the why (now). Laptops cut down the power going to the screen when disconnected from a power source to reduce battery consumption. The damage to the screen is minute enough to where the lower voltage doesn't bother anything but the higher one will; most likely because the wires have some damage and might be too close to each other or touching. It can be fixed.
Why is there a thin horizontal line flickering on my laptop screen?
That could be three things:Damage to the screen. If this is the case, it needs to be replaced, there is no way to fix a broken screen.The display “flex cable” which connects the display to the laptop motherboard from a connector on the back of the screen (but within the screen bezel) to a connection under the keyboard, passing through one of the hinges, is loose, crimped, or otherwise damaged. Reseating each connection may fix it or it might need replacing.Damage to the video card. This is the worse possibility because the video card in 99% of laptops is integrated directly into the motherboard and cannot be replaced or repaired.A good way to help rule out the video card is to plug in an external monitor and see if it gets video. You may need to press or hold the keyboard function key that has a picture of a monitor on it in order to switch output to the external display.Please note, there is a very small possibility there could be an issue with the external video port; if so, not getting any external video would not necessarily mean the video card was bad. Also note, I have had cases where I had multiple issues (display screen AND flex cable bad causing no video, video on external monitor is fine, but new screen flickers because the flex cable connection on the motherboard is damaged and cannot be repaired).
