Pismo will not start up
My Pismo will 'chime' after the power button has been pressed, the screen will light up but nothing else will happen.
I have tried pressing the Restart button (PMU). I have also tried starting and holding down the apple, option P and R buttons and waiting for two chimes (tip from the PowerBook manual). Same result.
I have tried to start up with the PRAM battery removed (and Airport Card removed). I have also removed and reseated the processor.
The machine does seem to be making some sound (whirring of some sort can be heard).
Can anyone think of a particular failure which would give this result?
Pismo 400MHz, 512 MB Ram, OS X 10.3.9
UPDATE:This is a follow on to my question (Pismo will,not start).
I thought that I had got to the bottom of the problem (hard drive failure)but now something has happened to open it up all over again.
I have tried swapping parts from a second 'spares' machine. I have tried to use the hard drive from this but I have been getting the same result as before. When I took the hard drive from the original machine and put it into the spare, it fired up first time!
Any thoughts on what is stopping the first machine from firing up properly?
