MBP 07: Immediate Boot Loop After Startup Chime: Please Help!

[legaleye3000]

I have a mid-07 Santa Rosa MBP. When I turn it on, nothing comes on the screen (not even backlight), but I'll hear the startup chime and 2 seconds later, it reboots and does the same thing. Here is what I have tried:

1. Reset SMU
2. Reset PRAM
3. Replacing HD
4. Replacing PRAM/CMOS battery
5. Tried booting off DVD (but it reboots too fast after the chime)

Any suggestions? Thank you.

Hi,

Have you tried booting while holding down the Shift Key? (safe mode)

Doesn't do anything different

Hi,

Try Command (Apple Key) and V.

or

Try Command and S.

Didn't work...

Okay,

Last try.

command-option-o-f

After that I got nothing.

Sorry.

edit - Actually that won't work either as your computer is an Intel.

Didn't work... Thanks though.

I think its hardware personally. Its out of warranty, but I'm wondering if it would qualify for the extended warranty for the defective nVidia cards.....?

Final answer.

Boot holding down the Option Key.

Now I am really out of ideas.

Nope . . . . .

Hi,

It never hurts to ask Apple. My buddy had his G5 iMac replaced with a new iMac last fall for free due to some extended warranty.

Best of luck!
