Hi everybody,
I have a Sony Vaio VPCW12J1E and i am having a problem with the LEDs of the screen.
The laptop was working fine until a month ago. Suddenly the back light stop working. I can see the windows desktop if i use i flash light but there is NO light from the LEDs. I have connected the laptop to an external monitor and the external monitor is ok but still no light to the laptop. I ordered a new screen because I thought that this might be the case but the problem still exist!! I also try to change the lcd cable without any success. I tried the old screen in a friend’s laptop and it was working OK. So I said to use his but when I connect it to my laptop I get a resolution problem from the beginning but i get light. I have also checked on the fuse in the motherboard close to the VGA but it was OK.
Any thoughts....!!!!
