If you're inclined, disassemble the laptop and try to find the manufacturer and part number on the LCD screen. NOT the laptop model or manufacturer, but the manufacturer and part number of the actual panel. There are several sites online (as well as ebay) that source replacement panels, but usually you need an EXACT replacement part as there isn't a standard connector for these things.

Well, the output is good to an external monitor so I'm going to give it a go and take apart the lcd housing. Stay tuned...

First thing I would check is the inverter. It will be a small circuit board with a set of wires (probably 2) coming in and wires leaving it. The input will be 5 or 12V DC, and the output will be 1000V+ AC (very low amperage). Check both sides of the inverter to ensure that DC voltage is coming in, and that AC voltage is going out. You'll need a multimeter to check that.
If that's good to go, then the backlight is probably suspect. If the AC side of the inverter isn't powered, then you need a new inverter. If the DC side isn't powered, then you've got a problem further upstream.

Well, I ended up sending the laptop back to the manufacturer to have them take a look at it. They called me last week and told me it was a motherboard problem. The tech explained that they didn't stock that model motherboard anymore and that it would be $400 to refurbish the old one. I had them send it back unrepaired figuring I could just hook it up to an external monitor (which I had done successfully before I sent it off).
Just got it back yesterday and now it mysteriously won't power on at all. Sabotage maybe? The thing was working normally excpt for the display when I sent it to them.

And that is why I will never send another product of mine to the manufacturer for repair unless absolutely necessary. Once upon a time, I had a Toshiba laptop and it brokded quite often. No matter what the repair (one time it was a hinge on the modem port) they ALWAYS reformatted the hard drive. WTF?? When they did fix it, they put defective parts in it. How can a hard drive fail every 2 or three months with only sporadic use??
I talked to a guy once that shipped a Sony Camera in for repair. It had an aftermarket lens on it and a memory card inside. Guess what? The lens or the memory card never came back and the repair company denied, denied, denied. That is why I decided to live with my Sony camera and its intermittent ccd fault.
Long Story short, they will deny any wrongdoing and you are just screwed up the pooter buddy.
