PowerBook G4 is stuck on boot - ready for help

My Titanium G4 (10.3.?) is stuck on the "Starting Mac OS X..." screen. The blue bar gets to the end and then just stays there. After more than an hour nothing new happens. I have tried PMU reset, OPT-CMF-P-R, CMD -S (thus fsck -fy, & sh /etc/rc) and reading over 100 notes on Mac Forum. I don't know what the next step is.

FYI: I never hear a chime and sometimes as I try to restart I get two very unusual signals. The first signal is a low emitting tone for about 3 seconds. The second signal is from the white "heartbeat" light at the center bottom of the lid below the screen. The light flashes 5, 6, or 7 times then stops. I have never read any post describing these signals.

The issue started after I allowed a security upgrade and (I believe) a Safari upgrade and then hit the button to accept the restart.

I have some situational issues too, if it helps to help me. I don't have any backup files or disks with me while I am visiting relatives in the Northeastern UK and my optical drive doesn't work anyway.

What can anyone suggest? Thanks in advance for your time and ideas.

G'day and welcome to the Forums.

Here is a link to this, or a very similar problem, on Apple Discussions. Not much you can do without your install DVD, but the post does talk about a failed logic board.

Fingers crossed for you that a boot from the install DVD and Repair Disk will work.

Harry..., I'll look at the Apple link. Did you ever hear about a way to borrow emergency repair disks or an install DVD? Thanks again.

If the PRAM was zapped and the firmware is confused, what are the next three steps I should/can take?

Sorry no suggestions without that install DVD unless there is an Apple store somewhere near where you are......

"In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once."
