    Model M105-S3015...the screen has a picture and the pc seems to be working ok....just no back light. Replaced the inverter with a new one but same thing. Pc will run an external monitor. Wondered what the voltage is out of the inverter to run the backlites.

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.

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 :-

Dell Inspiron 6000 Laptop Screen has Faint Image


It's a faulty backlight (screen).
Replace screen (same dell part number) with inverter, otherwise screen can be dark.
Here is how Dell part number looks (green):

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!!

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.
