A flickering screen indicates a backlit problem. I would personally change out the screen but if you want to do a complete diagnostics and take the long way in which you'll learn a lot.

Tools needed:

Dollar store jewelers screw driver set.
Soft cloth towel

To replace the screen only:

On the screen there's little screw covers on the corners of the screen, removing these sticky little covers will give you access to the screws that hold the screen cover on. Once removed get a guitar pick or even a finger nail and go gently around the screen. Once the screen cover is off you will see the screws that hold the lcd in place and screws that secure the hinges.

Locate and remove the screws that secure the lcd to aluminum side rails. Use the soft cloth towel to protect the screen from getting scratched during removal. Lower the screen towards the keyboard and lay it down on the keyboard.

On the back of the screen you will see a ribbon cable attached to the back of the lcd screen. GENTLY pull down the ribbon cable lock on both sides of the ribbon cable.

The only thing left connected to the screen is the backlight cable, GENTLY pull this plug out taking note of what color wire is on the top and bottom.

Reverse this instruction and happy computing

For COMPLETE laptop dis-assembly follow this link:

Follow this link for complete disassembly instructions with pictures for your laptop. You may want to skip to when the screen gets disassembled.

Hi - I have replaced lots of LCD screens,it can be done

HOW TO REMOVE LCD PANEL OF MY ACER LAPTOP.

First ===>>> Remove all power and battery

Each machine is different in construction and size,
but they operate in the same fashion,motherboard,power inverter,lcd panel and cable connecting them together,also there may be a wireless aerial and or camera as well inside the lids frame housing the lcd screen so be careful while dismantling the front frame,it should be a good tight fit,

the lid has a base and a front panel covering the workings of the screen and wiring in a compact frame,remove the screws from the front panel and lift the front frame free from the base,remove the power panel by the screen next to the keyboard this should expose the motherboard insides,then unplug the inverter from the screen,unscrew the screws holding the the frame and carefully lie the screen on a flat surface to unplug the data cable from the rear of the screen, top of the screen rear contains IC chips required to make the pictures,
DO NOT TOUCH THESE >>> STATIC KILLS

It dosent mater if the screen is already dead just remember this when you fit the new screen

Hope this helps,Misterdj

I have a asus x58l and it has a black screen. cant see anything


http://www.asus.com/Notebooks_Ultrabooks/X58L/#support_Knowledge

Don't know why I did that.

Asus Support. Those two words don't even belong in the same sentence. (Neither does Toshiba Support, or Acer Support)

Notice the large statement?

NEED SERVICE?

(In otherwords GOT MONEY?)

Rant over.

Janet,

The problem will be;
1) Graphics chipset
or,
2) Video Cable,
or,
3) screen Inverter,
or,
4) LCD screen

I'm betting it's the economical, and easy to replace - screen Inverter.

Laptop on, shine a bright flashlight at the LCD screen of the laptop; and shine at various angles.

See faint images?
Backlight is out, or screen Inverter is out.
90 percent of the time the fault is the screen Inverter.

Moving on........

A) Graphics chipset:
Laptop OFF, monitor OFF, connect a VGA monitor to the laptop.
The VGA port is on the Back of the laptop.

This is a General example of a VGA port (Connector), and VGA Cable,

http://en.wikipedia.org/wiki/VGA_Connector

Scroll down a little for VGA Cable example.
You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By factory default settings, the display should show on the external VGA monitor.
IF not;

There are at least 3 display options available;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down, and at the SAME time; tap once on the F8 key.
The F8 key is the Display Toggle-Over key.

(User Manual indicates not all laptops, may use the same Function keys.
Whatever Asus.
The Display Toggle-Over key has LCD on it, surrounded by a rectangular line. Has a small monitor icon to the right of it )

Display on external VGA monitor? No?
Hold the Fn key down again, and tap once more on the F8 key.

No display on external VGA monitor, indicates a problem with the graphics chipset.

Display ON external monitor, indicates a problem with the;
1) Video Cable,
or
2) screen Inverter,
or
3) LCD screen

Perform the 'flashlight test'. No faint images go on to the external VGA monitor test.

Post back in a Comment.
We'll go from there.

Regards,
joecoolvette

(There are NO service manuals available, to the public.
Thank Asus for that. To procede though can be done.

This will require a partial disassembly of the laptop, to include removing the Keyboard, and Palm Rest Cover.

Together we can accomplish this if needed.

May do something I never do, and that is because of no Service Manual available. May ask you to buy a replacement screen Inverter, and replace it.
Need other information above FIRST.

Average cost is around $25 to $30.
The plastic frame in front of the LCD screen is the Display Bezel.

The screen Inverter is located behind the Display Bezel, and mounted to the bottom of the LCD screen assembly.

(Clip or a Philips head screw)

Average example,

http://www.ebay.com/itm/100-Genuine-NEW-Original-Asus-X58L-laptop-Series-LCD-Inverter-08G21VJ10107-/290873311574?pt=LH_DefaultDomain_0&hash=item43b9668156

Doesn't require removing Keyboard, and Palm Rest Cover.
DOES require removing all power. AC adapter (Charger), and Battery.

My ASUS laptop doesn't boot and displays vertical lines when plugged in


Try pressing in near the bottom of the screen near the battery, you should be able to make if flicker and come back to normal, even if you have to keep it pressed in. I have the exact same problem on my U31F.
It's 95% a loose connector inside the screen, or near the hinges.
I'm trying to figure out how to approach it myself, but will probably end up taking to asus for them to fiddle with.

How do i fix a flickering screen problem of my HP Compaq 6735s laptop


The flickering could be a sign that your lcd screen is going bad and needs to be replaced. It could also be the video card inside the computer. Isolate the problem by connecting another monitor to the laptop. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok without flickering, then your video card inside the computer is good, but your lcd screen is bad. If the Borrowed monitor flickers like your lcd screen did, then your video card inside the computer is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Try tapping the back of the lcd screen's lid to see if the flickering stops, increases or decreases. It might be that the lcd cable located at the top on the back of the lcd screen is loose.Isolate the problem by connecting another monitor to the computer. You'll have to take the lcd apart to get to the video cable on the back of it.

Flickering screen


Try an external monitor to the laptop and see if it flickers. If it does, more than likely your video card is going bad. If it does not flicker on the external monitor you probably have a loose video cable or lcd inverter cable. Go back inside and remove the 2 cables that go into the LCD Inverter that sits at the bottom of the LCD Screen, then plug them back in. Then unplug the video cable at the top behind the lcd screen, plug it back in and secure it with a piece of tape right where the two connections meet.

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

Screen fliks change calor to pink if i move the screen or shake it it came back


Sounds like the cables between the display and the mainboard inside the laptop are broken and would need to be replaced. Those cables can be hard to locate, you may want to take the laptop to a repairer who can obtain the parts for it, or contact asus if you are still in warranty.

if this is a desktop computer then just replace the cable between the display and the computer.

Computer monitor flickers


Sounds like the lcd ribbon might have come loose. Or the lcd screen itself needs to be replaced. I have included a link here. The website shows detailed pictures about how to access the parts needed to fix this problem.

The ribbon i'm speaking of is just like the vga cable you use on a normal monitor. Since there is a limited amount of space in notebooks they turned this thick cable into a small flat ribbon.

Try to look and make sure all the connections are tight and as they should be. If nothing changes you will have to change the LCD display.
