Ok, I am the family tech guru, so my extended family brings all their crap for me to fix for free.
My aunt brings me her laptop, which had been run over by a car and the lcd was completely shattered. However, the external VGA port worked for viewing on an external monitor.
She wanted me to load windows XP on the laptop, which was not easy since it has an SATA harddrive, but I managed to make it work.
I was feeling generous and found a good deal on a replacement screen on ebay, and I bought it. I installed the new lcd and it was working like a champ.
I spent the next several hours hunting down the right XP drivers for her machine and installing windows updates and the like. I had pretty much resurrected the machine when out of the blue I get a BSOD. When I rebooted the machine, nothing on the screen at all. No POST message, nothing. the lighs come on, fan comes on, hard drive spins, cd rom seems to be spinning. My first assumption was that the screen just died after all, it was a used screen off ebay, but now I can't even get the external monitor to work.
Any ideas how I can verify that the problem is my screen and not my processor, motherboard, etc...
