Your machine has the Nvidia GeForce 8600M GT video processor. This GPU has had a history of failure and Apple has been replacing the logic board for free for up to four years after the date of purchase. They have been known to even do the repair after this date. I would contact Apple directly and see if they will fix it for you for free.

Hello!

Yes i know, but my computer older than 4 year. And i would like to find a way to repair somehow if it is possible. Somebody can help me??

You can not DIY - replacing a laptop video chip is a very involved and complicated process requiring special equipment. If Apple won't replace it some have had a temporary fix by overheating the chip to "reflow" the solder.

I'm in the same boat as Bertalan. The screen on my lightly used 2007 went dark in 2013. There had already been two recalls but there was no help for me. The same issue exists today, 2015, with a recall out for 2011-2013 models. Not impressed with apple.

it can fix your GPU issue. the NVIDIA G84-602-A2 GPU chip it can re-ball or replace. re-flowing is not recommended in my opinion.

A. power ON with boot sound no display also in external lcd
