Hi,
After a interrupted install process of HS...install was hanging hilmself..ends up in 1 hour of white screen..I had shut down the syst... after this my Mac Pro 2009 can't start or boot anymore. Keyboard, Mouse and Monitor dosen't correspond. It seems that all USB conn. are off. No light on the Keyboard (shift), just sometimes red light on the Mouse. Power botton glowing normal - fans and GC fans running normal... start sound didn't come .. just by holding power botton longer than 10 sec. --- >SMC ? -- I checked all.. but it dosen't works.

P.S. I had cecked my syst. (10.9) ...on another Mac. - running and booting fine.. // No warning light LED's on the board!!

Any help welcome !

Download the Apple Technician Guide for your 2009 Mac Pro, go to the part of the
Minimum Configuration Testing and check the diagnostic LEDs, around page 28 to 33 if I remember correctly.

See what LEDs are lit and what are off, then follow the diagnostic steps that Apple suggest.

With your described symptoms, my bet is that your EFI DONE diagnostic LED is off and you have a brick.

GPU defects can make a Mac to not boot in a way that is very similar to a brick, check with another know working GPU before buying replacement backplanes or a Mac Pro MATT card.

1.
I assume you tried a PRAM reset - Hold down these keys before starting up . . . . .

P + R + Apple Command + Option. keys

. .. . wait for THREE "Happy Mac Chimes ( if that works at all )​

2. ( To test whether your cMP will start up )
( remove all PCIe cards except your GPU ! )
If you have your original OS X install DVD and still have a DVD drive - pull the drive tray 1/2 way out, use a pin to open the DVD drive - insert the original OS X install DVD. You don't have a Macrumors SIGNATURE so we have no idea of your 2009 cMP's set up - good idea to make a SIG before your next post. Look at my SIG at the bottom of this post, it will give you some idea of what to list in your SIG

3.
Hold down the " C" key and start up. Whether it will start up depends on a lot of things.
If it DOES start up look at point #4

4.
Do you have a separate working OS X install on another hard drive ? If so remove the " failed install " drive and try the other working install drive.

I DO recommend doing the ( three chimes ) PRAM first

Good luck.

Hi, Thank you for your tips ! I will try the DVD workaround. Fact is no USB ! Ergo no mouse , no screen, no keyboard.. I'm completly blind.. hope that DVD treatment will work..

1. IMPORTANT : Did you do the PRAM /NVRAM reset ? ( 3 chimes )

2. Have you tried ALL USB ports ? Especially the rear ones.

3. Have you tried using a PC keyboard ?

4. I wonder if there are still any USB 2.0 PCIe cards for Mac Pros out there.

Did you press the Diagnostic button and checked the Apple Technician Guide like I wrote? No USB is a sign that the BootROM wasn't even initialised enough to enumerate the USB ports.
 
If your BootROM don't enumerate USBs, it won't make SATA ports work. Again, you have to follow post #2 instructions, eliminate the GPU as a possible cause of the brick, then confirm that EFI DONE is off.


Had to change the Logic - Backplaine - No one could help ..even not so called certified apple repair workshops - they are simply not schooled here on such old Mac's ...
