Dude, the issue might be with the LCD screen or Graphics card. hence request you to connect the notebook to external monitor and check the display in external monitor.
if the display is good on external monitor then it might be due malfunction of LCD screen.
if the display is bad on external monitor then it clear that graphics card malfunctioned.
In either case, i request you to contact manufacturer for availabe service options for the notebook.

Thanks and Regards
Your Friend

Seems to me that the LCD cables are not properly atached.
Double check all the LCD connections.
Your problem will be solved.

Check the GPU and motherboard are OK by plugging an external monitor into the VGA socket and then booting. If the external screen is OK, replace the LCD screen.

Hook a spare monitor to the video output usually on the back, if picture okay! the LCD screen will need to be replaced on the laptop, but if both show the same symptom it is the Video Graphics Card normally built into the motherboard.

There is too much blue on the screen & not enough green coloring


Have a very close look at the blue and see if it's perfectly uniform across the whole screen.
If it is then altering the hue or colour temperature settings in the menu may help.
If it's not then either there are heaps of pixel failures (appearing as small rectangular spots) or degradation of the polarisers (green may be affected more than the others).
If you show the menu, do the white areas appear bluish.
If the lamp is very old then colour changes start to happen.

Hi I have a Sony vaio vgn-nr21z I don't know how to go bios setup pls tell me how to do that


Hi,
Please follow these steps,there are different way od going to BIOS depending on the brand of the laptop.

1
Turn on your computer

2
Hold down F2, this will take you into BIOS. On some computers it might be the DEL key, or F1.

3
Change the settings in BIOS to what you desire. You will see parameters for various devices, if your BIOS allows it, you can even overclock the CPU.

4
Look at the BIOS menu. You will be able to see the make, model, and capacity of your hard drive, processor speed, time and date, among many other settings.

5
Click "exit without saving changes" if you make a mistake, and nothing will be changed.

Hope this will help...Your response is very much appreciated...

Hp dv9000 switches on to show coloured lines on screen.


Hello

My first guess is that the screen circuitry has gone bad - although fixable. Use an external monitor to verify this. If the external monitor is fine then the screen circuitry is bad, if the external screen shows the same problem then the video chip or associated circuitry has gone bad. My company fixes these all the time.
