I want to end this question

The problem was in videochip. I resoldered this and now macbook turn on without problems. But very pity, that in my Macbook it is very difficult problem with videochip because of unlucky setting of chip. I suppose that the last owner soldered chip very bad, so now my Mac can't take a big workload.
