First check all the cable connection and if all is perfect then press "J" at the system boot.
Otherwise, attach this monitor in another system by which you can clearly understand whtzs going on.

Packard Bell OneTwo M3700 PC boots up but no display


most of the time on older monitors you can set the refresh rate in safe mode and that will, most of the time, resolve the problem otherwise time to purchase a newer monitor.

On my asus Eee Pc 1201HAB the display shifted to the left so the left side is partially cut off, how do i fix it?


1) Looking at the User Manual right now, and do not see a Hot Key on the Keyboard, that shifts the display.

[ Hot Key is also known as Special Key. The F1 through F12 keys at the top of the keyboard, and also for your model, colored keys on the keyboard ]

It could be the Screen Resolution is messed up. Not set at the correct settings.

Right-click on an empty area of your desktop screen.
At the bottom of the drop down list, click on Properties.

In the Display Properties window click on the Settings tab.

The screen pixel resolution should be set at 1366 X 768,

http://www.screentekinc.com/Asus_EEE_PC_1201HAB--12.1-inch--1366x768-wxga_hd-laptop-lcd-screen.shtml

In the middle of the Display Properties window, you see the blue subheading - Screen resolution

Right under this small subheading is a Slider.
The Pointed 'arrow' with the green tip, and top, slides back, and forth on the 'line'.

It should state 1366 X 768.
If it does not;

A) Left-click on that green tipped Slider. Hold the left mouse button down. Move your mouse, and move the Slider. (Drag)
Move it to the Left to Decrease the screen resolution, or to the Right to Increase the screen resolution.

Can't set it to 1366 X 768? Post back in a Comment.
ALSO, the Color Quality should be set to -
Highest (32 bit)

If not click on the blue down arrow to the right of this box.
In the list left-click on Highest (32 bit)

Now go below to the right, and click on Apply.
After go below to the Left, and click on OK.

Still no joy?
Believe the problem is hardware related.

Could be something as simple (?) as a bad Video Cable.
(Goes from the motherboard, up under the left Hinge, and then up into the Display Assembly)

Could be the screen Inverter.

However the Eee PC 1201HAB is supposed to use an LCD panel, that has qa series of LED's for backlighting.
Newer backlighting that uses a series of LED's for the Backlight, doesn't require a screen Inverter.

There were some LED backlit LCD screen, that DID use a screen Inverter. Mostly the older models of laptops.
This is what makes me think your LCD screen's Backlight, (And LED), may use a screen Inverter,

http://www.batterystyle.com/asus-eee-pc-1201hab-screen-p-168219.html

Scroll down,
"5. Disconnect the power cable and video cable from the Asus EEE PC 1201HAB Lcd panel. The power cable connects the screen's power source, the lcd inverter, to the backlight lamp attached to a side of the panel."

Probably just a generic form, and didn't take in consideration that the Eee PC 1201HAB netbook, uses a series of LED's, as a Backlight.

May not have a screen Inverter.

To explain;
Primer:

An LCD screen cannot produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

(Click on the window with the computer monitor in it )

It needs an additional light source. A Backlight is the additional light source.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.

[ LED = Light Emitting Diode.
CCFL stands for Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

{Average thickness of a CCFL bulb is 2mm. That is a a little larger than 1/16th of an Inch.
The average length is almost as long, as the LCD screen is in height]

A screen Inverter is used to CONVERT the power from the laptop, for the LCD screen, and Backlight.

Do not see any listings for an Asus Eee PC 1201HAB netbook, for a screen Inverter. Believe the LCD screen uses LED's for a Backlight, and does NOT use a screen Inverter.

Which means if the problem is in the Display Assembly, the LCD screen itself will need to be replaced.
The LED backlighting is built-in.

[Hmmmm, I see a trend going on here that I do not care for, and just woke up to it. Have to replace the entire LCD screen, and cannot just replace the Backlight, or screen Inverter? Sounds like Ka-ching $$$$$ for somebody!

A screen Inverter usually averages from $20 to $40+.
A Backlight ( CCFL) usually ranges from $10 to $15.
An average LCD screen can range from $80 to $300+.]

How to know if the problem is in the Display Assembly?
Use a VGA monitor, and connect it to your laptop.

A) Laptop OFF, monitor OFF. Connect a VGA monitor's cable to the VGA port on the laptop.
(Left side rear. This is an example of a VGA Cable, and VGA connector { Port on a computer },

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

You can use an older CRT type of VGA monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable attached.

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By default the display should automatically show, on the external VGA monitor.
IF not;

There are at least three display options:
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and hold it down. At the same time tap once on the F8 key.
The F8 key is the Display Toggle-Over key.
(Give it a few seconds. Sometimes it doesn't happen right away)

Still no?
Hold the Fn key down again, and tap once more on the F8 key.

Is the display off to one side on the external VGA monitor?

No Graphics


Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout 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 correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

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.

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,

My monitor screen is ok for awhile but suddenly turns a dull yellow color. I just bought it a few months ago.


Hi,
you must adjust the display settings in the software program that was being used to change the display setting.
  • If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
  • Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
  • If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
  • follw the another steps-
  • Replace the monitor power cable.
    1. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    2. Replace the video cable. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    3. If the monitor does not work after replacing the cables, replace or service the monitor

    I have an Evesham Explorer A5500 notebook Laptop and earlier when i was usuing it the screen became covered in white lines i rebooted to try and fix the problem but now when i turn on my laptop the screen...


    Take a bright light and shine it on the screen when it is on. Can you barely see any display, but really dark? If so, the lamp or the lamp inverter has failed (some laptops use LEDs instead of CCFL lamps and has no inverter either).

    Just hooking up to another display doesn't necessary tell you anything if it doesn't show anything. As sometimes you have to change a settings in the BIOS, use the Fn key plus another key that looks like a monitor, or change it through a display menu on the screen.

    Monitor displays breifly then goes to blank screen


    If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.
