Too bad it's not a PowerBook G4 15" 1.67 mhz. 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.

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.

Well, followed the instructions explicitly, and let it cool slowly, but
now it just gives 3 beeps on power-on. 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.
