Your problem could be a faulty backlighting panel or the power connector for the backlight needs reseating.
There are two connectors on the LCD that are connected to the motherboard, one for the video signal and the other for the backlight power supply, reseat this connector and hopefully your problem will be fixed.

Lines and flickering while browsing


Does it flicker on anything you do? Possibly the screen cable is loose, possibly the screen is becoming faulty

You will need to take to a repair shop to determine which.

Blank or shaky screen


Display Configuration A flickering screen may be caused by the computer detecting incorrect display settings as it starts or returns from sleep. It can also come from changes to the screen resolution settings caused by a new program or update installation. Verify screen resolution before assuming the issue is hardware related. Faulty Inverter Next to the display screen behind the plastic screen bezel is a small component called the inverter, which supplies power to the screen backlight. The flickering indicates the power is not reaching the backlight. To fix the issue, replace the inverter. Faulty Connectors The wires and cables traveling from the display around the hinges and into the motherboard tend to wear at the hinge area. Over time, the opening and closing of the screen causes this wear. The solution is to disassemble the plastic casing of the laptop, reorganize the cables so they have no interference from hinges, or replace the cables and connectors with new ones made specifically for the computer make and model experiencing the issue.

Laptop monitor flickering


You could have a faulty ribbon video cable or a loose video connection to the motherboard. Reseat the video cable connection to the motherboard.
To get to this connector you most likely need to remove the keyboard to get access to this connector.

How to solve a flickering screen for toshiba satallite m200? as i open my laptop its hang and the screen is flickering...


@crisanne_21

Most of the time, that cause of that flickering screen is a defective LCD flex cable or sometimes called LVDS cable (this is the cable that attaches the LCD panel to the motherboard - it can be caused by a loose connection or simply, it just may have worn out due to opening/closing the lid). The only way to fix that is to replace disassemble the computer and check if there's a loose connection on that LCD cable. If disconnecting / reconnecting the LCD cable doesn't fix the issue, you might need to replace it Disassmebly guides can be found here.


Good Luck

My laptop lg x130 stuck for almost a month when i turn on it the screen has no display


The display of your laptop is one of its most integral components, and if it is exhibiting problems, it is one of the most frustrating issues you can experience as a computer owner. A display can experience a variety of issues, from the mildly annoying flickering of a screen, to it not powering on at all. Identifying the problem is the first step towards assessing whether it can be fixed, or if it is time to get a new computer.

  1. Brightness
    • If the brightness of your screen is intermittent, or is flickering, it is likely that the inverter is broken. The inverter is a small board that controls the brightness of your screen. It plugs into the display and the motherboard, or the main brain of your computer. Try a new inverter board, which you can get from your computer manufacturer, or from a computer supply store, by taking out the inverter from your display casing.
    Garbled Video
    • If there is garbled video on your screen, it may mean that the low-voltage differential signaling cable, also called an LVDS cable, has begun to malfunction, or that the graphics card is failing. To check your LVDS cable, open up the computer and unplug the LVDS, which will be running from the motherboard up into your display. Plug the LVDS cable back in and with the computer open, turn the computer on and check the graphics. If it continues, you may need to take the display out of its casing and unplug the LVDS from the back of the screen. If the graphics issue continues, try another graphics card. If the new graphics card is in, and there are still graphics issues, the LVDS will need to be replaced.
    No Video
    • If there is no video on the screen of your laptop, it can mean one of two problems: that the display has completely given out, or the logic board is not supplying any video to the screen. If there is no video, try moving the screen forward to back several times to see if video appears momentarily. If so, there may be a loose connection. If no video comes on, hook up an external monitor to the computer and see if any video appears. If video does appear, it is likely the screen has died. If there is no video, your graphics card has failed. Depending on the logic board holding the graphics card, you will either have to replace the graphics card, or the whole logic board.
I hope you find it very helpful. Best regards.

My laptop britness is not working properly


Is it flickering, or just having promblem adjusting the brightness? If is is flickering, it could be a loose wiring connection. If it is not adjusting brightness, check via using your FN keys, then try clicking the battery icon in your taskbar and adjust brightness through it. If nothing happens, it could be your screen inverter.

Screen flickers


If light is good and picture flickers, then it is either a bad LCD ribbon cable, or cable not well placed into connector, or a bad LCD display, usually it is the cable.
If picture flickers like light is dimming out and coming back, then it is the LCD lamp, probably in need of replacement.
In some rare case a faulty Video card is causing the problem.
Usually to fix this you need to take apart LCD display and upper laptop plate, to reveal the display cable.
