I need a logic board for mine. I had it out the other day to try to repair a bad ethernet port and evidently it freaked out the ATI video chip on it, because the display was corrupted and the external DVI port refused to work after that. :p I had just finished loading Mint PPC Linux on it and everything worked except for the ethernet port (which didn't work with OSX either). Since then I've had it apart 3 times trying to find something obvious that may have caused the glitch, but nothing is showing up. So, it looks like it's time to find a logic board since the ATI chip is integrated on it. :p ---- I know it sounds strange, but remove the motherboard, place on wire rack in preheated convection oven at 375 for 20 minutes. ALLOW to cool <in oven for at least 1 hour> before removing. Fixes video probs on lots of HP laptops. ----- No virus found in this message.

Heh heh, sounds crazy, but I'll try anything once. It's pretty well useless as it is. Thanks Cindy, I'll give it a whirl. Btw, are you sure about that temp setting? Seems like it may be high enough to melt the plastic connectors where the power, touchpad, etc., plug in. -- We put tiny pieces of AL foil over the sensitive parts. Remove any cables, ribbons, etc. Make sure the foil covers the plastic connectors, but NOT touching the motherboard. The object is to get the solder to reflow on these tiny connections. Because they are so small, the 375 for 20 min works fine, but LET IT COOL IN OVEN or the motherboard will crack. This usually gives video for another 3-6 months, and MIGHT work twice on the same motherboard, but then it is really time to replace it. ----- No virus found in this message.

This is usually indicative of a bad RAM chip. Had a known-good spare here and tried it too with the same results. Guess it's time for a logic board replacement. I found several on E-bay that are pretty reasonable and guaranteed good. Guess I'll give that a shot. I'd really like to get this working again. :) Mint Linux PPC 11 works really nice on these... plus it's update capable.

Not to mention I now have a working ethernet port too in addition to the Airport Extreme Wireless. These old notebooks really work nice with Mint Linux for PPC. First time I've EVER been able to do full screen Youtube video on a G4 with no drop-outs or glitches, thanks to 'Minitube'! Plus, I can actually get the latest updates and security patches when necessary. :))
