Do a simple test - Try connecting it to an external monitor or LCD monitor (at work, a friend or neighbor's) - if you get the same thing on the LCD and external monitor, then you've got bad on-board video (MB); if you only get abnormal output on the laptop's screen and the external video is fine, then it's likely a bad screen...

Please follow the diagnosis outlined in this article to check whether the backlight lamp or the inverter board are the root cause of the problem or not:

If you connect the external monitor & nothing is displayed on it, then this means that both the backlight lamp & the inverter board are fine. The main indicators in these cases are the sound, and the hard drive LED on the laptop's case. If the laptop sounds just like it always does for a minute or two after being turned on, it means it's going ahead and booting the operating system, but the video processor or part of the motherboard circuit for video output has failed.

Toshiba satellite p25 s509 lapto video output problem im using a

What type of Video Card in in the laptop?
check the laptop case on left side of keyboard sometimes stickes are there saying what type.
I have seen ATI Mobility cards in laptops that have all the software working on the machine properly, but the display driver is either bad and cirrupt and causes the machine to reboot, or its a fualty video card that can cause the machine to crash.

Easy way to check, boot the machine and as windows XP boots press the F8 key (this enters safe mode) when menu appears choose safe mode with networking. and let it continue.
if it boots up and continues to a display and doesn't crash, the video driver is bad.
then just uninstall the video driver, then go to the nabufacturers website and download a new video driver for your model laptop.

When turn on nothing appear on screen

possible issue would be the LCD, video controller/card or motherboard. Connect an external monitor to the laptop. It works fine and the computer boots properly, it will be an issue with the LCD. Request an LCD replacement if in warranty, otherwise, purchase one. If same issue with external monitor, check for signs of system booting up. Listen if you hear the welcome sound that you usually hear when Windows has successfully loaded. If you get this, request a replacement for the video card. If video card is integrated to the motherboard, request a motherboard replacement.

It sounds like the video card could not handle the monitor in the board room - As it is unless you have a graphics based laptop you rarely get a high quality video card built into your laptop.

Causes aside boot your computer in safe mode - This is done by tapping F8 several times during startup

A menu should pop up - select boot in safe mode

A long list of text will pass in front of the monitor - Do not fret this is just Windows telling you what it is loading.

Once at your desktop you should be able to see everything clearly

Right click on your desktop

Goto Properties


Drag the Screen Resolution down to something more appropriate e.g. 1024 x 768

Cannot display anything at all,sounds it is working but, cannot dispaly boot screen and rest???

Try connecting an external monitor to the Dell Latitude D820. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor has no display, then your problem is with either the video card or motherboard located inside your laptop.
