Not sure where to go on this one. I have a Dell B130 laptop with a dark screen. It's not dead, cause if I take the bezel off and put a bright enough light behind it, you can see the picture very dimly.

I replaced the inverter and it gave me 3 seconds of back light, but now it's back to being dark again. Can you replace just the light, is it even worth it? Or should I just replace the entire screen. The laptop works great otherwise and even runs W7 decently.

Thanks.

Well, your sort of into it now in the sense of sunk costs. Someone here should be able to specify a test procedure that would tell you if the CCFL is defective. For example, using a meter, determine if the inverter is supplying voltage, but current is not measured flowing thru the CCFL or no voltage drop across the CCFL. (Probably best if you had an O-Scope.)

In general, CCFLs are not difficult to replace.

You are better off replacing the screen itself. Odds of you finding the bulb are slim and the odds of you opening it without breaking the screen may be even slimmer.

That's what I was thinking Matt. Plus the entire screen assembly is cheap, about $60.

That's good. There are some odd screen sizes and those can be $100 or more sometimes. If you can get the entire assembly that can be easier. Otherwise you may have to get the 2 bracket off the screen. That requires a very fine tip philips head.
