Like mayer I've searched high and low for an inverter to be sold individually. I recommend you buy a cracked screen or a functioning entire unit off of eBay with a cracked screen to acquire the inverter. If you buy the entire unit you can sell the remaining parts to offset your cost. The LCDs for this I've seen are running between $500 - $800 USD. Here is the guide for replacing the inverter unit.
My apologies to all you Mac experts, I do not mean to butt in. I just follow this question since I just recently "inherited one of these. I do not even try to pretend to be an expert on this. I did my research and this is what I came up with. The transformer that Max is referring to, might be what I attached as image 1 . Looks like there are about 7 of them. These are readily available at places like this. The panel is an LG Phillips TFT LM240WU2 the datasheet for the panel is available here and it does have the pinout for the inverter listed. And it looks like the board is available right here.
