Sony VAIO Turn on - black screen

I have a sony VAIO VPCEE3WFX and when I turn on the laptop and the screen black all the time. I can't see the VAIO logo, bios, anything. I tested to remove, memory, hard drive, CD Drive, etc.. Second test to remove battery, AC power and then press the power button. The problem continues. I hope someone can help me.

 

Have you tried using HDMI and VGA to hook up the laptop to a monitor or a tv? If your laptop shows up it suggests that the screen may have an issue. Otherwise, if nothing shows up it suggests that the gfx may be the issue. Good luck with it though!

 

It also did that test and nothing from video. The laptop turns on the power button light bulb, battery, etc but can not see anything.

 

You probably need to enable to VGA output, it won't output anything through it unless you turn it on. The problem is to turn it on blindly.

The same thing happened to my SVZ last week, there's a thread about that here somewhere. To see anything through VGA, you have to boot up and login (blindly), then press Fn+F7, then right arrow, then enter. That will *probably* duplicate the screen through the VGA output, if that doesn't work, try pressing right arrow twice instead of once. And make sure to wait a few seconds after each time, it might take a while for the monitor to display anything.

 

if you can change the lights of the keyboard (caps lock for example) then it is a screen issues.
Otherwise, it could be the motherboard.
