"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.

If you turn on your laptop and no display ever shows, your issue is with either the LCD backlight or the motherboard (since the video card is built-in the motherboard). This will be easy to diagnose.
1.) Plug an external monitor (one which you know works) into the VGA port of your laptop.
2.) Turn on the laptop.
3.) Hold down the FN key (lower-left corner of the keyboard) and press the "CRT/LCD" key (it will be located on the number keys or F1-F12. You do this to tell the laptop that it needs to send the video signal to the external monitor instead of its built-in LCD screen.
If you can see a display on the external monitor, then the issue is with the laptop's LCD screen (about $200 for the part plus labor to install). If you can NOT see a display on the external monitor, then your problem is with the motherboard ($300-$500 for the part plus a lot in labor cost for installation).

Windows Vista® 1 Right-click an open area of the desktop. 2 Click Personalize. The Personalize appearance and sounds window appears. 3 Click Display Settings. 4 Select the external LCD monitor in the drop-down menu.Monitors and Displays 51 5 In the Display Settings window, move the Resolution slider bar to the left or right to select a screen resolution that matches the native resolution of the external LCD monitor. 6 Click OK. Windows® XP 1 Right-click an open area of the desktop. 2 Click Properties. The Display Properties window appears. 3 Select the Settings tab. 4 Select the external LCD monitor in the Display drop-down menu. 5 Under the Screen resolution section, move the slide bar to the left or right to select a screen resolution that matches the native resolution of the external LCD monitor. 6 Click OK.

There is often a function monitor key on the laptop, located near the F7 key area, the icon looks like a monitor on|off and is typically in blue. this key is to be used in combination with the Fn key to enable, disable the external monitor or enable both monitors or just the laptop. Press the key combination until your laptop panel lights up while the monitor is plugged in. Now check your extenal monitor refresh rate and resolution slider settings by right clicking on your desktop go to properties / video settings. (please note monitor settings are under advanced). You should see two monitors in there now. use "identify" button so you know which one to work with. on the external monitor settings, decrease (slide left the slider all the way). If you can set the monitor refresh to 60Htz. Lastly take a flashlight and check if you can see a shadow of your screen on the external monitor, if you can that means the backlight is not working and likely needs the inverter replaced. Hope that helps ! Cheers

you could have accidently changed to external monitor with Fn +F(the number is 8 on my comp but could be 5 on yours-check keys on top of the keyboard it has a picture rectangle / little TV), anyways to check that attach external monitor to your laptop(must have a VGA cable) if you have a picture on external monitor try Fn + F(depends on what you have on ur keyboard) it should bring you a window with choices to choose laptop LCD or external LCD choose 1st one .
hope that is it.

Turn off notebook. Remove the battery. Press Power button. Notebook should start working. Wait for 15 secs. If the screen still blank press Power button and hold it for approx. 4 seconds until notebook is powered off. Then press power button again. Bingo, problem should be solved.

Connect another external working monitor to the computer, if the other works then get lamps and inverter replaced.

Display Toggle - <Fn> + <F5> will toggle from external monitor
Screen Blank - <Fn> + <F6> will turn the LCD off

hope that helps.

Might be that the graphics card is overheating.
