I have an old ibook g4 that has worked for a loon time after I replaced the original hard drive. However, After startup I can not get the monitor to light up. any ideas?
iBook, Mac OS X (10.4.1)
Did you make sure to get a Parallel ATA hard drive? SATA is not compatible with the iBook.
Hi. Have you tried the F1 F2 keys? Do you have access to a monitor and mini dvi plug to check if it's the LCD.If your getting a startup chime try a pram reset. Command/Option/P/R keys at start up while holding down the power button for three chimes. Also PMU reset. With ibook off hold down the power button until you hear a beep or the sleep light flashes.
You may have to check the wires inside to see if any other section of them
was accidentally damaged in the process of replacement of the hard drive.
Do you have an external display adapter for VGA? That may be able to help
see if the internal display itself has an issue; though I'm not certain how to
get the external display to work on first boot w/o Display preferences set...
If you happen to have an externally enclosed FireWire hard drive with a system
installed (a clone of the original OS X would be OK) that could be used to test
the hardware and also used to re-install from such a backup.
{With a second Mac capable of supporting Target Disk Mode, with FireWire cable
you could see if the internal hard drive you just put in, is OK; it should be seen
by the healthy second Mac as a hard disk drive; testing, formating, etc can be
done that way, if needed, depending on what vintage & ports a 2nd Mac has.}

Not sure what else to suggest, since there are items that may have failed which
had nothing to do with your attempt to restore the hard disk drive. With the install
DVD in the optical drive, do you get any activity from the computer with the C-key
held down through the restart process and if needed, held for several minutes?
Sometimes, the symptom you state, may be due to a failure or damaged logic board
or some connectors, or broken solder joints where main components are affixed.
Sorry to not offer any solution in the matter.
Good luck in any event...! 😐
