I have a DELL LATITUDE D830 in my posession. It was brought to me with a dim display, with the client saying it was dim on one side, bright on the other. Naturally, my first thoughts were "Okay, probably the CCFL."
I get my hands on the system and, sure enough, the CCFL had burned out. Of course, at that point the CCFL burns out COMPLETELY, leaving me with a dark screen. Thankfully, he provided the CORRECT CCFL and inverter (part no., and all. Brought a tear to my eye.)
Here's the thing: I've replaced both the CCFL and inverter and... Now the CCFL definitely works, as the bottom of the screen is lit-up (although, the bulb is lit, and perhaps an inch or so of the bottom of the screen), but the rest of the display is dark. It still works perfectly, boots fine, etc., but dark.
Also, I've replaced the LCD Power cable with one from an identical system that was scrapped, on the off-chance it was the cable. No change.
Also, also, I've tested this machine with an external monitor from the VGA port on the back, which works perfectly, which - I think - rules out the video card being an issue.
I'm at a loss. Thoughts?
EDIT: Also, also, also... The LCD is dim from pre-POST/DELL screen through to Windows.
