The LCD backlight has failed, you will need to replace the LCD assy (about $200)

I have a Dell Inspiron B130 and the screen is black. I can see a background faintly and hear sound but am not able to do anything because the screen is so dark. What do I need to do to fix this problem?
The problem is most likely the back light and the fault could be the inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to determine the fault and fix :-

Disappearing screen picture
Sounds like the battery is weak and it tried to save power by dimming the screen. You might need to contact the manufacturer and get it replaced if under warranty. If not, mess around with it a bit and if you can't solve it then buy a new one from the company.

Image on the screen is very faint
It sounds like yout lcd inverter is blown. You can usually get a new one and replace it yourself. I would look on ebay. Its just a small computer chip that fits inside of the monitor housing.

My Dell Inspiron 6400 is extremely dark. +brightness does nothing
Hi there.
Yes, if you can see a very faint image on the screen that indicates that the inverter or inverter coil has become defective and needs looking at or replacing.

Good luck and thanks for using Fixya!!

Dark screen on my laptop
It still could be the inverter or the lamp (CCFL). Even with a meter, you must likely won't know for sure. Plus it can have 1800v there at times. So that is pretty high. Sorry I don't have better news for you.

Dell inspiron 5150 dark screen, faint image in background
If it showed a pinkish tint on the screen before it went out it could be the backlite. If you can see a faint screen when you turn the room lights out it chuld be the inverter. Inverters are cheap ... a used one for around $8 on ebay. Try that first. Make sure that you buy the EXACT model that is presently in your laptop.
