Power Mac G5 Boot Failure

Hi,

I don’t think this is a new problem. Various posts have similar data, but the one I have might be little bit different.

The Power Mac G5 is failing to boot or fails to load the display. The following are the observations
1. The Computer powers up. The monitor is powered on, but no display.
2. The Fans are running (I don’t know if this is normal or noisy!)
3. I feel the keyboard is unresponsive. I don’t see the caps lock light switching on. In addition none of the key combos are working. And I am unable to open the CD compartment either from keyboard or mouse.
4. I managed to pry open the CD compartment and insert the install CD. But since I could not press C during boot, I guess it was futile.
5. I removed the power supply and tried resetting the PMU or SMU. Nothing happened.
6. I changed the 3.6V system battery from another Mac, no good came of that.
7. I re-connected the cords and removed and replaced the RAMs, nothing.

Any help in this regard would be great. The machine is very critical to our lab. Please HELP!!!!
 
Check your install disk disks and run the hardware test. You might have had a hard drive that went south.
 
Hi Satcomer,
thanks for the reply. As i had earlier said. I am unable to boot the machine from the install Disk , or even target disk mode. The keyboard is unresponsive. Now what to do ? Is there anyother wayout ?:-(
 
I tried another keyboard and also another 3.6V battery, still the same thing ! Thanks in Advance !

:-) . I called Apple too. I got the same two answers as the others have got the SMU reset solution and ctrl+option+p+r solution. And neither worked.

HELP PLEEEEEZE !! :-((
