MacBook Pro 2008 no power after reball

[lord]

Hi,
I had this problem many times, and i never resolved the problem.
So as you would know this series of macbooks have a huge problem with graphics (G84-602-A2), and the reball would fix the problem. So, i did a reball on the board for the THIRD time and now it just doesn't respond to the power button.
Has anybody had the same problem?

Could be that you fried the GPU.

Consider buying another one and simply attaching it.

Also, since the NB and CPU are pretty much attached to the motherboard, there's a possibility those have come loose after all those re-balls.

Just a thought.

I have A Idea... Can you Try To little bit Shake The GPU In Heating Using Infra. somethimes the BGA ball are not Align Proper? I hame many Expirence Before...

Measure the resistance across the capacitors on the GPU after lifting and if you get absolute zeros on any of the them then the GPU is definitely fried and like thesloc said consider buying another one and simply attach it.

I have couple od GPUs already, buy them before, since this MacBooks are prone to GPU cold joints.
So i tried with 3 GPU-a, reballed again and again on couple of MacBooks, even reballed the northbridge, southbridge and the CPU. Yesterday reballed KBC....

bad memory perhaps? try swapping it out just in case.

Re: MacBook Pro 2008 no power after reball

Tried RAM preplacement, although with bad RAM the laptop should turn on

Cmon, somebody should know about this error!

i hate macs but i will post for general laptops with no power after reworking

if it had power then there is a 99% chance that you have a bridge or short underneath the bga or the chip is dead

if the laptop does have dedicated video you can remove the gpu and test it should still have power

but i have no idea about macs proprietary pos
