For the past two days, when I start up my ASUS G1 the screen shows no video. I can hear the ASUS startup sound but no picture (and no windows startup sound). If I leave it on sometimes the startup sound will sound again. The day it died on me it had done a weird split black screen, I restarted and everything was okay. Then when I shut it down the screen stayed black. I tried again and it worked. Now, there's no way to get it to work. I've tried taking out the battery and power cord, left it for hours. I've tried blowing out the fan incase it was overheating.

Black screen - no flashing white cursor in the upper left corner - no picture at all, i.e. the initial Dell start-up screen doesn't show up either:
- LCD is dead or isn't getting a signal - not an easy fix; or
- the LCD isn't being sent a signal - holding down the function [Fn] key and press display Function key to toggle through its settings (LCD panel only, Rear VGA output only, both LCD and VGA output)
Black screen - flashing white cursor in the upper left corner - the screen goes black after the windows loading screens come up but before the windows login screen comes up - it is probably a windows video driver problem. Try starting in Windows Safe Mode with VGA. Press [F8] after the Dell startup screen disappears to access the windows startup menu
Hook a monitor to the video output, if picture is present it means the inverter board is the most likely problem, [located under the screen] the second possibility is the backlight behind the display. Now if both screens show the same symptom it is the video graphics chip.
To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.
If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.
In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.
In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command. If all fails Sounds like your operating system needs to be reinstalled or you can do a system recovery to set it back to when you first bought it.
Hook a spare monitor to the video output usually on the back, if picture is okay! the problem lies in the inverter board, "just below the screen" or the backlight behind the LCD display, or the video cable from the screen to the motherboard has come loose from the plugin. But if both show the same symptom it means the Video Graphics Card is defective, normally built into the motherboard.
If you turn on the computer and the lights come on and the fans start but you see no picture, try turning up your volume to listen for the windows startup sound. If you hear the windows startup sound it is likely your video card or the monitor on the laptop. If you hear no sound the power could be faulty or the computer could be completely fried.

If you are only getting a black screen and you are sure it's booting (how do you know?), then the problem would be the incorrect video settings in Windows. In this case, you might try starting in safe mode and resetting the video adapter. If you see stuff on the screen as the system boots but then it goes black, then it's definitely a Windows issue. If you see nothing at all but hear the system starting, then it's a hardware issue involving the video card.
