First, look at the screen in darkened room to see if you can see any slight glow from the sreen, if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter baord to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there are some troubleshoot you will have to do to find out the causes of the problem you are having.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

No data is sent to the screen


When the screen goes completely black, shine a very bright flashlight closely at the screen. If you can see the image, then the most likely problem is that the backlight inverter has failed.

The inverter is a circuit board that works like a flourescent light ballast. If the inverter fails, there is no backlight, and the screen is black.

Since the invertor is a high-voltage component, I would also listen for any unusual sounds associated with the failure: e.g. buzzing, whistling, popping.

To rule out some sort of connection failure, see if you can recreate the failure mode when using the TVs internal setup menu. The setup menu does not rely on any external inputs....of course neither does the volume control or channel indicator on the screen.

Computer turns on but screen stays black


This is often caused by the screen lights or screen failing. Try looking at the screen from different angles in different light conditions, you might just be able to see the image.

Replaced screen computer comes on, but screen stays black.


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 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.
