Boots Up with chime, blank screen nothing happens

My MBP suddenly doesn't turn on properly. The computer turns on, but to a blank screen. I hear the startup chime and the HD whirring. Also, after a few seconds the keyboard lights up.

I took out the HD for testing, and everything looks fine.

Any ideas?

Answer this question I have this problem too

Is this a good question?

Could be a GPU failure. The MBPs A1226 and A1260 use the problematic NVIDIA GeForce 8600M GT graphic card. If you don't have video on an external monitor contact Apple cause your computer could be repaired free of charge via the Apple special Nvidia replacement program.

Or if you have a spare computer you can use that as an external display.

Curious ! How would you do that ?

The easiest way is with ScreenRecycler but I'm pretty sure that won't work with a computer not turning on properly, so there are a bunch of ways to just connect to the LCD,etc. I've never tried or need to try any of them, however if you look at online forums you can find many ways, you need some adapters I think though.

Try connecting to an external display, could just be a bad LCD.
