Laptop display gone wild. Help!

Is my (partner's) laptop display kaput? It alternates between a blank screen (although the backlight is on) and strange wavy pink-green effects.
The system outputs to an external monitor, and I've updated the bios and display drivers. I have also taken off and apart the screen to check the cable connections, with no change. What's happened? Motherboard? Display? Cable? Specs inside.

2007 Dell Latitude D820
NVidia Quadro NVS 110M graphics chip
Windows Vista 32 bit
I've read about the problems with this chip which led to the Dell warranty extension
and the NVidia settlement
. It appears that it's too late to claim benefits from either, so I'm on my own here (right?)
The effect is also strange. From my research, when screens fail it's usually in a jagged-horizontal-liney type of way. This is more like a flowy-lava-lamp failure. This is the best image I could capture.
(That's the laptop running on the external off to the left.) I can usually make the effect happen when I hit the Fn-F8 combo that swaps between external and onboard displays. Anyone seen this particular failure before?
Finally, it looks like replacing either the display or the mobo will cost $100+, but the connecting cable can be had for much cheaper. Is there a chance that would fix it? Is there anything else I could try, or should I start shopping for a new laptop?
