I have a Sony Vaio SVT14115CXS, running Windows 8. The computer was working fine up til yesterday.  I did a normal shut down.  This morning when I tried to start it up, it gave me a blank white screen.  I tried Assist, Web and Sony buttons, nothing work.  can not go to BIOS.  no logo.  I tried the difference methods suggested on youtube.  I took out the RAM, put in another computer, it read.  I took out the hard drive, it read as an external.  what else can I do? any suggestion?

Hello sindyc.

 

When you try to switch the laptop on, is it plugged in or running on battery?

Hi.

 

You might try the basic suggestions at Sony's support site...

https://us.en.kb.sony.com/app/answers/detail/a_id/38217/c/65,66/p/48903,49902,71345,71353/

 

Try the suggestions that do not require resetting BIOS or seating your RAM Chips.  See if the other simpler suggestions help.

 

Steve

Hi,

 

Was having trouble sign in sorry for the late reply.

 

Steve, I have tried your suggestions, I even borrow an external monitor (a good working one) to see if there is something wrong with my display.  Nothing  :orange: ... no display (just white screen), no logo, no OS load, what else to do?  is there something wrong with the board?

In order to use an external monitor with this laptop you will need to change the settings between the laptop's display and an external monitor by using the Fn and the F7 keys.  Press these together until you see the options for the monitor.

 

Are you using a HDMI cable to connect the monitor?

the monitor I used is a older model.  It doesn't have HDMI port, only SVGA. 

I try again... It works! Finally, the hard drive light and the wireless light came on and  I can see the content of the hard drive on the external .  I turn off to try to use Assist, it doesn't show on the external (after pressing Fn F7) what is wrong with my laptop?

If you can't get the computer working with a known good monitor and have tried using the keys suggested without success I would be inclined to suspect that the integrated graphics has gone south.

do the screen needs to be replaced or/and other parts? 

I saw something on youtube about inverter, can it be that part?

There are two components in the display that can go bad, the display screen backlight and the inverter.

 

Take a powerful flashlight and shine it on the display with the laptop on.  If you can see the desktop it will be either the backlight or the inverter.  The only way to truly test one or the other is to replace it.

 

What bother's me is the fact that you were unable to get a monitor to display the desktop.  If you did this correctly and the integrated graphics hasn't failed you should have been able to see the desktop on the monitor.  If you change both the backlight and inverter and it still doesn't work this will indicate that the integrated graphics chip has gone south.  The bad news is that you would have to replace the whole motherboard if the integrated chip has failed.

That's a choice only you can make.
