I just fixed my A1181 MacBook that had a back-light issue.  My issue was sometimes the back-light would stay on for maybe 10-15 minutes, other times it would only be for a split second, usually the latter.  I bought an inverter board from iFixit but that didn't work.  I also bought a new back-light bulb from an online shop (hard blue shift in color) in case my bulb was  bad.  Upon dis-assembly, I noticed one side of the back-light bulb had a very bad solder joint.  Out of curiosity I re-soldered the connections and my back-light has been working for days with no issue.

Maybe this will help someone.

Full disclosure...this isn't the most easy job in the world.
