Re: Sony Vaio VPC-SB26FG cannot power on
Hi there!
The cap that is in the red box was faulty. But when I applied current to GREEN points, I did not know this yet.
The reason I applied current to these (GREEN) spots is that these are main GROUND and VIN (+) in points on this board. And when you apply current to the shorted cirquit, it starts to dissipate heat. The component that gets warm is most likely to be defective.
In my case it was the capacitor outline in red.
