Hello
I have a Sony vaio flip 13.3"
I was browsing the Internet and suddenly the screen started flickering, multicolor, with a buzzy noise. Then shut off
Now It won't usually start at all, even it does, about one in ten tries, it won't boot. The fan starts working, and the caps lock key lights up, it was on when it turned off.
I tried disconnecting the battery, and ram, and connecting and turning it in again,but nothing. I also tried connecting an external monitor, no signal.
Any ideas? Buttons won't work, so I can't press anything,and the screen remains black. Any ideas?
