Screen black but external works OK

Texto:

I'm debating on whether this is a dead LCD display or a bad video controller. Since the external display work (VGA adapter to Dell 19").

System Profile does not detect any displays connected, though the external connection *does* work.

I've found the video adapter 661-4673 for about $190, and this is definitely the cheaper of the 2 components. A replacement LCD is about 3x that. :(

I checked the graphics ROM version and it matches the newer version mentioned in the Apple support doc [http://support.apple.com/kb/DL71|DL71]

Any suggestions on diagnosing this further?

This had been running 10.5 and I'm in the process of upgrading to 10.6.
