A/some capacitor/s on the logic board have failed somewhere, you
could locate which one by buying a can of electronic service aid
freeze spray (ebay), then spraying one at a time with the Kanga
opened up wide ( ie dismembered but connected!), if you find the bad
one you then have to replace it, no mean feat.
PMu you have tried so its the logic somewhere.
Good luck!

Subject: Kanga weirdness
From: Mark <[EMAIL PROTECTED]>

So I've got this PB G3 original (3400 style AKA Kanga) that I've been
trying
to bring back from the near dead. It's got the "hiss of death" I
suppose
you could call it. I've replaced the PRAM and the PMU, but plugging
it in
gives nothing more than a hissing through the speakers. Every so
often (1
in 100 times if I'm lucky) resetting it will get a chime, but nothing
else.
I haven't heard a chime in ages. Until today. Somewhere in my
googling I
vaguely remembered reading that coldness helps circuits reconnect (or
something - you can see I really retained a lot about it), anyway I
decided
what the h*** and I put the whole computer (sans battery) in my
freezer for
about 10-15 minutes. Lo and behold upon the first resetting it
chimed and
brought me to a screen with a flashing floppy (the drive is wiped
clean). I
could hardly believe it. Unfortunately the flashing floppy
eventually froze
(computer style, not ice) and it would go no further. However, once
again
upon freezing the unit (ice style, not computer) it started up again
(I had
a cd in the drive this time ready to install an OS) but it soon froze up
(computer style). I can repeat this over and over and over, but it
only gets
going for a minute or so until it gets too hot (I'm guessing) and
stops. So
it's not dead yet. But what's next? Any ideas on where I should look
for
bad circuits based on this limited info? Thanks all.
