Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

It could be a Operating system issue, or a hardware voltage issue.

I would place my bets on the OS. Simple solution is to update your driver, if that does not work, reinstall your OS

Outputting to an external display is only possible through Windows. As you stated External Display works with the computer, its sure that the issue is with the LCD. Performing a System Recovery is not going to help. The screen needs a replacement. To confirm this restart the VAIO and press and hold the F2 key and check if the computer boots to BIOS, if it boots to BIOS, then the screen is fine. Based on the information you have provided, I'm sure that the LCD will exhibit the same issue in BIOS and screen will stay blank.

As far as the recovery process is concerned, if you have not changed the preinstalled OS in the computer, you can still access the VAIO Recovery partition from Help and Support. You can also access the Recovery Center following the below link: C:\Progrm Files\Sony\Recovery Center.

To initiate a service process, you can visit the http// or can get in touch with your favorite technician.

Hope this helps.

I need to know what operating system you're using (like windows vista). However, it seems like the control has moved to the LG screen, and not laptop. You can set several options when connecting a monitor to a laptop - both screens are available, one screen is off and the other screen is off.

Please post your operating system so that I guide you how to change these settings.

Get an old monitor CRT or LCD. Connect this to the back of your laptop to the appropriate connection. Turn on this monitor and your laptop. Now on your laptops keyboard are some blue highlighted keys called function keys. Press and hold the one marked "Fn" and then press the F7 key (on my Sony - yours may be different but the key with a small blue rectangle with LCD inside a foward slash to what looks like an oval with square sides) this is the external monitor key. If the external monitor comes on with the laptops screen information then your mercury lamp in the laptops screen has died. Then a reputable repairman can replace your screen and lamp for $200. - $300. If nothing appears on the screen then most likely the video chip in your laptop has died. Replacing this will require a new motherboard for the laptop. You should contact Sony about price and any extended warranties they may have,
