Could be the backlight of the laptop. When the laptop is running try tilting the screen back and forward till you notice what may be your OS...

If so your gonna have to contact a local repairer for your laptop brand...

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.

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 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,

Screen does not work any more. Got a new LCD but still no picture.


you said that you want a display card. first no extra card can be added to the laptop. that is not possible. and second if your lcd is not working then the inverter card might be gone. it is a small card which converts dc to high voltage ac so that the screen can be back lit and run. if this has gone it can be replaced and you can again restore ur screen.

you can check the working of the graphic card of you laptop by connecting external monitor. if that also not working then you need to replace ur motherboard. these are the solutions.

so in order to make sure your motherboard is ok. just connect an external monitor. and you cannot upgrade your graphic card as it is final in laptop.no upgrades for that.

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.

I have a packard bell EASYNOTE MZ36 the screen has gone blank, not even a faint image on the screen. but works fine on a external monitor?


First try and press and hold the FN key and then press the F4 key. The screen will disappear from the external monitor and should appear on Laptop. Try a few times and see what happens. This is a common problem and usually can either be a keying error or the back light operation of LCD screen needs replacement. Cost can vary from $70 - $150 AU. Go to ebay and find if there is a replacement for you. See how you go and let me know!

Dell inspiron 1501 laptop screen has vertical lines in middle of screen, have taken apart to check connections but still there, any ideas ?


If the display is ok on an external monitor, then the problem is probably a bad tab board (tab welds) and the lcd will have to be replaced. If the external display is the same as the lcd then the inverter board or video card is bad.
