hi - I'm using an old G3 ibook which I love and am trying to remain faithful to despite the screen only coming on at certain angles and the motor in the combo drive having given out. I've had the logic board replaced once - it's in the dodgy batch as far as I can tell. However now the screen is completely black at start up. I can still access everything via firewire from a desk-top mac (ie the hard drive is fine and all the data is still there) and occasionally it will start up - date reset but otherwise OK - but seems to be suffering from a loose connection somewhere in that when I moved it a bit it flickered and died. I'm wondering if it's the logic board again but have been told this are not typical symptoms - I don't really have money to spend on it as I'm studying this year. Anyone got any advice?

Welcome to Mac-Forums, j-dubh.

There's a couple of things you can try like Resetting your Mac's PRAM and NVRAM and Resetting PowerBook and iBook Power Management Unit (PMU).

Report back to let us know how these go.

If resetting doesn't work, head over here and rip that mother open. Nothing to be afraid of.

i would check out the inverter board and inverter cable, i am going through similar problems with my g3. the screen would only light at certain angles and if it moved it went black again.

so I found out that it is the logic board (again) but apparently Apple don't want to replace it even though it's in the serial number range of the dodgy batch. That seems a little unfair to me. Has anyone else had any luck getting logic boards replaced?

Did my own fix-it job after some help from here and I took the bottom casing off, stuck some paper/card (ok there's a fire-risk but I'll deal with that) in there on top of the square in the metal at the appropriate place to put some pressure on the bad connection. It's working fine. Thanks to you all.
