Most likey, bad news im affraid, its the screen just going bad. Usually theres nothing that can be done. You can try reseating the ribbon cable and see if that improves it, but most likely it wont, they usually have only so many operating hours before the crystals or plasma goes out, depending which it is. Plasma usually goes out quicker than LCD.

Try finding a replacement on Ebay or online somewhere.

Good luck.

P.S. im asuming of course that you know a little about what you are doing and it isnt something like the display settings or contrast.

Screen on ma2a gateway doesn't turn on. Is it the video card?


Borrow a monitor and plug it into the VGA port. That might tell you whether the graphics card is bad.

I have a gateway netbook and the screen turns white after startup. What can I do to fix it?


Sure wish I knew the exact Model Number of this netbook. It's on the bottom in a white Service Tag, or sticker.

All I can give you is generic information.

On the back of the netbook, or on one of the sides, is a VGA connector. (Perhaps even the front)

This is a basic example of a VGA cable, and a VGA connector, (To the right is the connector),

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


Netbook OFF, monitor OFF, connect the VGA cable of the monitor to the VGA connector on the netbook.

You can use a CRT monitor that looks like a small TV, or an LCD flat screen monitor that has a VGA cable.

Turn the monitor on. IF it is a CRT monitor give it a few minutes to 'warm up'.
Turn the netbook on.

IF the display does not automatically come up on the external monitor, (The VGA monitor), press, and hold down on the Fn key, and at the same time tap once on the Display toggle-over key.

Again generic information;
The Fn key is usually located on the Keyboard near the CTRL key to the left.
I have no idea where your Display toggle-over key is.

This key will be one of the Function keys at the top of the keyboard. Either F1, F2, F3, F4, F5, F6, F7, and so on.

There should be a monitor symbol on this particular key. Will look like an empty rectangle with rounded corners. Supposed to represent a monitor. There may be an arrow to one side of it.

The arrow represents the display moving over.

Different laptops, (netbooks), have different options.
Usual is;
1) Just the internal monitor of the laptop
2) Internal monitor of the laptop, AND the external monitor
3) External monitor Only.

Do to there being more than one option, you may have to tap the Display toggle-over key more than once.

A) White screen also shows on external VGA monitor?
You have a bad graphics chipset.

For most laptops, and I'm betting with this netbook, the graphics chipset is soldered directly to the motherboard. This is Integrated Graphics.

Another term for Integrated Graphics is OnBoard Graphics.
ON the motherBOARD.

This would mean replacing the motherboard.

(IF the netbook does indeed have a graphics card, the card could be replaced, and not the motherboard)


B) Display on external VGA monitor is okay?
There is a problem with the Display Assembly.

Essentially, the entire upper half of the netbook, is the Display Assembly.

1) Display Cover: The plastic top cover of the netbook.
2) LCD screen
3) Display Bezel: The thin plastic frame in front of the LCD screen. Resembles a picture frame
4) Inverter (Screen Inverter)
5) Webcam (IF installed)
6) Brackets which hold the LCD screen to the Display Cover, LCD screen frame, Hinges, various screws, and so on.

Primer:
1) An LCD screen does not produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp. (Lamp = Bulb)
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale,

This example is just to show you where one type of Backlight is located, and what an average Backlight looks like,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

With a LOT of laptops, and probably this netbook, the general repair method for replacing a Backlight is to replace the LCD screen.

An LCD screen is composed of layers. These layers are held in place by the Display Frame. A thin metal frame which surrounds the outside edges of the LCD screen layers. Also resembles a picture frame.

As you can see from the above link, the Backlight is accessed by removing the Display Frame on one side, or all together. This allows the LCD screen layers to move around. They MUST be kept, or put back in the exact location they were in, as set by the factory.

This is why the general repair method is to replace the LCD screen, for those who do not possess the technical skill of replacing, OR the manufacturer does not offer just the Backlight bulb.
{LCD screen = $$$$$. Backlight bulb is usually around $15 to $30}

2) Inverter:
An Inverter converts the electricity from the laptop for the Backlight.
In 90 PERCENT of Display Assembly problems, the fault is the Inverter.

OR, it may just be a loose Video Cable, or Inverter Cable.
The connections may be loose.

This requires partially disassembling the netbook, down to the connection of the Video Cable TO the motherboard, to see if this connection is tight, and may also require disassembling the Display Assembly partway, to see if the connection of the Video Cable TO the LCD screen is tight.

{You cannot just eyeball the connections. They need to be physically checked to see if they are plugged in tightly}

Requires partial disassembly of the Display Assembly, to see if the connection TO the Inverter is tight, and FROM the Inverter to the Backlight is tight.

Connections prove to be tight, visually inspect the sheath of the Video Cable for obvious signs of damage. If the sheath is damaged, there is a good chance that one of the thin tiny wires inside it has become stretched, and is broken.

Obvious signs of damage, or not, I would suggest removing the Video Cable, and with a multimeter set to Ohms,(1K) check the continuity of the individual wires in the Video Cable.

Be sure the problem is not the Video Cable.

Video Cable proves to be good, replace the Inverter.

(Replacing an Inverter is a simple task, and the cost of the Inverter is economical enough to warrant this type of procedure, IMHO)

Still no satisfaction? Replace the LCD screen.

Post the Model Number in a Comment, and I'll make this solution more custom to THE netbook you have.

Hello , everyone and experts people. I have a Fujitsu Siemens Esprimo Mobile V5535. laptop good start, green LED lights up, but i have a black screen without any background applications. I tried to pick...


Hi dejandan1

Sorry to hear you are having problems. The very fact you tried an external monitor shows you have some good IT skills. As long as you know this monitor works it is a good test. As you have no image try toggling the video output signal by using Fn (Function) and the CRD/LCD (Cathode Ray Tube/Liquid Crystal Display) keys or Alt (Alternate) and the CRD/LCD keys.
philswift_7.jpg

If this does not workthen it is either
1. Laptop on board graphics failure
2. Laptop LCD panel failure
3. Laptop inverter failure
4. Laptop backlight failure
Turn on your laptop and look closely at the screen, can you see what you would normally see but very very dark? If so it is the backlight. If you cannot see anything, which is likely, then it is the inverter, actual panle failure or grahipcs chips on the motherboard.
http://www.daileyint.com/hmdpc/lcd.htm


philswift.gif Above is a link and flow chart that will help you.
It is most cost effective to send or take the laptop in for repair. You can replace inverters yourself but there is guarantee it is that. If the graphics on the motherboard has failed then all you can do is have the motherboard replaced. If the laptop is slow and old it may be time to consider a new laptop. If the laptop is under warranty, goto the Fujitsu Siemens website and log a under warranty repair.

All the best, Phil

I have a hp laptop. was on line and screen went black. and will not show again. it strats up sounds but black screen.what do i do


1) Do you have a VGA monitor that you can use for an external monitor?
{VGA monitor is also referred to as a CRT monitor. Looks like a small TV}

The back of the laptop, or side, has a VGA port. The VGA monitor is plugged into it.
{Laptop off}
Then the VGA monitor is turned on, and allowed to 'come to life'.

Now turn on the laptop. Press the Fn key down on the keyboard, and hold it down.
Now press the Monitor toggle over key.
Since you did not state the HP laptop Model Name, and Model Number, I can only give you generic guidance on this.

The monitor toggle over key has a monitor screen symbol on it. It will be one of the F keys.

(It's an External Monitor toggle key.
Press it one time and the display toggles over to an external monitor.
Press it again, and both the laptop LCD screen, and the external monitor have a display on them.
Press it once more, and the display goes back to the laptop's LCD screen )

If display shows up on the external monitor, you have a problem with the display of the laptop.

Primer:
An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is used as an additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp {Bulb}
Similar to the fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.

{Average Backlight is 3 to 5 inches long, and half the diameter of a No.2 pencil.
The Backlight is located on one edge of the LCD screen}

An Inverter is used to provide power for the LCD screen, and the Backlight.

90 percent of the time the problem is the Inverter.

Inverters are relatively cheap, and if I knew the Model Name, and Model Number of your HP laptop, I could give you a link to HP Support where you could download the Service Manual for free.

This way you would have a manual to show, and detail how to replace the Inverter, and I could guide you.

I could also give links for your perusal for Inverters.

There is one more thing however.

HP Pavilion DV2000, DV6000, and DV9000 series laptops, have a graphics chip overheating problem.
The laptop comes on, the blue indicator LED lights light up, but the LCD screen is black.

This video explains why, shows a solution to fixing the problem, and details out a lot more than I am privileged to state here,

http://www.youtube.com/watch?v=bnkQNmKauEc

Have further questions regarding any of the above, please state in a Comment.

Acer netbook AO751h screen does not work, external monitor works fine.


Hello !

Since an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

Hope this helps.

Hi There, I've been experiencing the same setback as Kenneth. My lenovo 3000 flashed off and even if I boot it, the screen is still black.How ca I fix it?./ Ty


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

When laptop is powered up, nothing shows on screen. I can here the audio intro but no display. Model is: MT3421


Try connecting an external monitor and see if it displays, if it displays OK you might have a problem with your inverter circuit or the back light of you laptop's LCD. If so you have to bring it to the repair shop. cheers.

Gateway flat LCD dead


I'm not sure if your referring to the lcd monitor (gateway brand) or a laptop's lcd screen not working anymore.

1. if it's an lcd monitor...
a. test monitor in a different pc before assuming the problem is the lcd screen
b. replace the monitor if after testing monitor is in deed the item failing.

2. if it's the lcd screen from your gateway laptop.
a. you may be able to attach a regular analog monitor to the paralel port on your gateway.. test and see if the monitor that you attach will give you a picture (you may have to toggle with some some keys on your laptop keyboard to make have the signal going to the "externa" or attached monitor.
if the other monitor does not work either.. you video controller on your motherboard on your laptop may be failing and you may not have other options that to replace your laptop.
b. if the external/attached monitor works.. very likely the problem is the lcd screen for that you need to get a replacement and you may have to contact gateway to find out about pricing (or places to send your laptop for service if you're still within warranty). if you have an old laptop you may have to considere simply replacing the unit as buying a new lcd screen may very likely be more expensive than the same working laptop.
