This Compaq Presario 2700 has very dim screen. I have tried all the basics like Fn+F8 for brightness control and also hooking up an external monitor. The external monitor works just fine. The brightness control doesn't work at all. Either making it darker or lighter. You can still barely see the images in the background and start menu etc..
So I came up with that it has to be the CCFL, or inverter.
Question #1: Is that all possible causes for this? Those two items I mentioned.
Question #2: Can you point me the way for instructions on replacement of these items.
