I don't think you had backlight issues like you thought you did as the set should have shut down the backlights totally as soon as it sensed over voltage or over current, I'd try a new main board and see if that fixes things up for you
Try to follow the inverter to backlight connections---either a loose or damaged plug (look for any plug with tape on it at the plug first) or on the board that powers the lights a bad solder connection or connections where plugs connect.
The picture board on your monitor is faulty or bad, since it goes
black after few seconds, it means the
board of your laptop has developed fault.
The best thing for you
do now is to take the laptop to a local repairer within your vicinity
to help with the replacement of the picture board
because the fault is not something you can fix yourself. in order not to
How dim is dim? If the picture is still visible just like half as bright then your have backlight tube problem and unit LCD needs to be replaced, not worth repair price. If the picture goes out almost to a black screen where you can just bairly see a faint image then you hold the screen just right then you have a backlight inverter issue. If the problem is the inverter then you should be able to replace a few parts and get your unit back going. If you think you can open the unit up and maybe solder a few parts then I would open the case and look for bad capacitors on the power supply board. I can send you pictures of what to look for if you are interested. We also have a repair service for those units, most power issues run $15.00 plus shipping. Let me know if you need help opening the unit and checking parts.
your issue with your laptop is a faulty ccfl BackLight Inverter, the display uses the backlight to illuminate the lcd screen, the inverter is used to illuminate the cold cathode light in the back of ther lcd theirs countless places to laern about it on google.

If your laptop screen is dark, it could be the backlight,inverter, or bad lcd. You can test the backlight by starting the laptop and give it a few seconds to load and take the laptop in a dark room and shine a flashlight on the lcd and see if you can see any pictures or icons. If you can, you may just need an inverter to correct the issue, If not, you may need to replace the inverter and lcd both.
If you find that you need parts to correct the issue. I would suggest that you begin with replacing the inverter first, as they are usually less expensive.
If you can supply me with the model number of the specific laptop you are having trouble with and I can try to locate more information on replacing the parts.
