So there are quite a few 15" lcds on ebay that don't have AC adapters.
You can get a 12V 3W adapter from here:

for 22 dollars.
But I had a thought....which is always dangerous.... 🙂
How much power does the backlight & inverter consume? Could I maybe get away with powering this screen with one of my 12V 1.5 AC adapters that I have laying around?
Basically, does an inverter account for roughly 1/2 - 2/4rds of the power consumption of an LCD? What do you guys think?

On average at least half. With larger panels which use more CCFLs you approach 2/3rds, so yes you should be ok, measure it just to make sure - you don't want to blow a thermal fuse in the PSU.
so how would one go about determining or measuring how much power the backlight required and thus how much weaker a power supply one could get away with?
