I've got a white macbook 2.16 I believe. The screen/display will turn on when booted up, but only stay on a few minutes. I got it off craigslist this way. When I first got it, it wouldn't come on at all. I replaced the inverter with one I got off ebay that was probably used. I have tried 4 different inverters in it (all used I think) they all respond the same way. Screen comes on for just a few minutes then the light goes black. If I disconnect the power to the inverter after it shuts off, then reconnect it, it will light up again for a couple seconds only. If I leave it alone, it will come back on after about 20 minutes. Does this sound like I have a bunch of bad inverters, or a bad lcd screen? It also drives an external monitor flawlessly the whole time and keeps an image displayed on the screen even when the light dies.
