First of all, you have to check whether you can see video signal with surrounding light tilting the screen.
If you can see dim image, all you have to do is replace back-light inverter or fix it. Usually, the fuse is open and you can connect it by simple soldering.
If you can't see dim image, it is another problems.
Give it a try.

Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.
Check the power supply.Hope the notebook receives power from the battery or the Ac adapter.We need to ensure there is no issue with the power supply.boot the notebook to the safe mode.If it boots to the safemode perform a system restore.In case the notebook does not boot to the BIOS,connect to an external monitor.If we still do not get a display,its the video card
Hi it sounds like your driver is missing or corrupt , this may be the case if u have recently installed windows, go to control panel click on sytem icon then click on device manager button under the hardware tab, have a look then under network adapters to see if there is a yellow warning icon if so make a note of the name and you should be able to download the driver from this location. its near the bottom under networking wireless.
You set it to Multiple Monitors (if you move the mouse, you will probably be able to see it on the TV once it "goes out" of the laptop desktop). You need to change output mode to external S-Video.
First of all try hitting Fn + F7 key to switch to Ext-S-Video. If it works, that's it, of course. If it doesn't, TV output is not enabled.
Right-click on the desktop to bring up the Properties, go to Settings. You'll see two monitor images there, 1 and 2.
Click Advanced, then go to Displays. You'll get CRT, TV and LCD. Turn on the TV button and tune your settings.
At this point, the hotkey Fn + F7 is enabled to cycle between LCD and TV.
If it still doesn't work and you see the blank desktop, go again in Display Properties, choose LCD as Primary Display, select Secondary, and verify that "Extend desktop on this display" is NOT checked.
mostly the button is found on the left float side of your laptop 'IBM'. with two icons of a computer. please make sure that the button is on the side of the icon that shows a computer with weaves. so that your able to check the wireless access points you have in your range. Wireless Connection:
Start > Control Panel > network connection>
Show network connections. If there is an X on wireless connection
then connection is disabling and if no X then connection is enable.
make sure its enabled.
Right click on wireless network connection and click view available wireless networks.
You should see a list of available wireless networks
Then select the wireless network that you need to work on and click connect.
An icon in the lower right hand corner of your laptop should eventually appear stating that you are connected.
Then this will show you your wireless connection.
