Its not a usual thing to happen, Just try to restart your laptop and check it if you get anything on the screen. It might be a operating system issue (in that case you will see the main screen of your laptop while starting like brand name ) also it might be a screen issue (in that case you can try to connect this laptop to any external monitor and check it) or it might be a hardware issue (normally caused by RAM)

SOURCE: Why did my HP Pavilion ze2000 screen go black?

john79:

I know that you had a chat about this matter, and I hope that your issue was solved. However, I had made a note of it when I saw the chat go through. I was unable to help at that time, but remembered having seen something of this nature and wanted to follow through on it.

Although the ze2000 is not listed, other 2000 models are listed in the following link as defective - and recognized as such by HP - with this very specific defect. (Please see http://h10025.www1.hp.com/ewfrf/wc/fastFaqLiteDocument?lc=en&dlc=en&cc=us&product=18703&docname=c01087194.)

Again, if your issue has already been solved, congratulations. Otherwise, I hope that the information provided here will be of use to you, either in fixing the equipment problem yourself (perhaps with a BIOS update) or by convincing HP to do something about it. At least you would be armed with good solid documentation of their recognized issue!

If this information assists you in resolving the problem, please take a moment to rate the solution at a "FixYa" level. If you do not feel that you can rate at a "FixYa", please post back with more information regarding what has occurred subsequently and/or more details regarding the situation, and I will gladly help you until we have reached a definitive solution. Thank you for using and rating FixYa!

SOURCE: lcd screen black on laptop. External monitor works.

Defective CCFL backlight may has the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering 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 replacing the CCFL lamp


Connect an external monitor to your laptop and power it up, 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 and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

SOURCE: Inverted Colors When Laptop Screen is Moved

hi
you are absolutely right.

there are basically two connections.

  1. at the motherboard end.
  2. at the display end.

any of the connector may be malfunctioning.

i ll suggest you not to open it yourself if you dont have prior experience in it.

while it wont take much to repair its not a costly affair.

if your system is under warranty it can be repaired for free.

if you find the solution helpful plz rate me carefully.
thnx

My son has managed to turn the screen on a Philips computer monitor so dark we can't see anything and I don't know how to turn up Model number 227E4LHAB/00


Look on the monitor front panel, there will be a tiny picture of what looks like a Sun and then a forward slash and an Arrow pointing up, that is the screen brightness control.

Grab a flashlight. When your screen goes black, shine the light on it. If you can see a faint image (press the Windows key and see if you the start menu pops up) then your inverter is going out. They are not expensive but depending on how time consuming it is to replace it, it might be easier and cheaper to just get a new monitor.

Vaio LCD problem


Periods.......Nice little items because they denote the End of a sentence.
See how this works?

"I have a vgn cs36gj, I was working with it, suddenly the LCD became pale black, I connected it to external monitor and it has a picture, sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

Now you try it.........

"I have a vgn cs36gj. I was working with it, suddenly the LCD became pale black.
I connected it to external monitor and it has a picture."

Okay, I got that part.........

"sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

WHICH LCD?
Laptop LCD?
External monitor LCD?
Man on the moon LCD?

1) If the external monitor LCD goes 'pale black', the problem is the graphics chipset.
This I do not believe

2) If the laptop LCD goes pale black, this I believe.

Post back in a Comment.

ANYONE KNOW WHY MY TOSHIBA SATELLITE L645 BECOME BLACK SCREEN BUT THE PROGRAM STILL RUNNING ?


you probably don't need a new screen it's probably your screen inverter that's going. It's just a small strip at the bottom of the screen wjth a little circuit board. If you google screen inverter and the make and model of your laptop you'll see what I mean.

Hallo , I have compaq presario c745ee , and suddenly the screen getting black but every thing is working , sound , fan sound .. every thing , I connected the laptop to a lcd and it is working probably , I...


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 rather than a slow degradation, the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.

Philips monitor problem


Check that the pc to monitor vga lead is not loose at both ends, check your graphics drivers are upto date, although it could well be a monitor fault and replacment required, as don't think they are worth reparing these days
