Having problems with your Sony VAIO VGN-S170 PC Notebook ?

Hello, I have a vgn-s170 laptop that I just installed a new screen and motherboard. the video chip heatsink/fan is not running and the screen does not come on. what can i do


Answers :

Have you tried connecting it to an external monitor? Are you sure the heatsink fan is not defective? If the screen works on an external monitor you know the video card is good. As long as the cable is plugged into the motherboard to provide power for the heatsink then it's either a bad heatsink fan or the motherboard connector for the heatsink is bad. My money is on the heatsink fan if you can get video from an external monitor.
