Replacing Logic Board on 933MHz iBook G4 (14")

[Littleodie914]

Hey guys,

I have an old iBook G4 with a dead logic board, everything works fine for about 10-15 minutes, then the display stops responding. The hard drive continues to spin, processor still chugs, etc. I'm going to leave it running iTunes in a few minutes and when it freezes, hit the space bar to see if the actual machine still responds. (In which case I would be sure that it's the video card, or some cable in that area.)

My question: I'm looking on eBay for replacement logic boards, and I'm wondering how specific/universal they are. Obviously, it needs to come from a 14" iBook, but does it matter what processor speed? Eg. Will a board from a 1.2GHz iBook work?

I have the iFixIt guide, and I'm not too worried about wrecking the thing, so it's just a matter of making sure I get the right part. (How about this one: Linkety ?)

Thanks!

I'm pretty sure a board from the 1.25ghz would work. The 1.33 and 1.42 were a little bit different I thought. Actually the boards are identical to each size of 12" and 14", just the connector for the battery is different which could actually be switched around if you are good with soldering. I wanted to drop a 1.42 into the 12" form factor.

Try pressing on the bottom near the battery release. Press it firmly to see it the video comes back on. You can sell that faulty one on ebay for around $30.
