    Hi Guy's..

    I have a powerbook G4 titanium and it fails to power on.

    Can someone offer me any advice??

    Following advice from other forums
    I have checked the power from the Pram battery and it's showing 3.8v
    I've reset the pram (using the reset button on the back), also pressed cmd, ctrl & shift).. and still with no luck.

    Can anyone please advise me on what to try next??

    Many thanks in advance.

    have you tried checking the ram cards because I had a g4 tower 2 years ago that refused to power on so I looked inside and saw a half in half out ram card

    but what do I know that was most likely a fluke that I fixed it

    Yes, I've checked the ram..

    I'm thinking that thee must be a fuse on the logic board that has blown but I'm unsure...
