Testing old iBook G3 parts?

Apr 30, 2007

I have an old Apple iBook G3 with a failed logic board. Apple did have a recall for this particular model but it has been long since expired, and as you may have guessed, the logic board failed.

Well, luckily for me, I found quite a few on eBay and made a purchase. After swapping out the logic board, it seems as if I was either cheated and sold a defective logic board, or the LCD suddenly stopped working as well.

Anyone have any suggestions as to how I can test to see whether the LCD still works? I don't have any extra iBooks lying around to just do trial and error.
