Have you pressed the appropriate key sequence to switch the video to the external monitor? On many Sony laptops that's fn+F8.
If you want to use it on an external monitor just download and install the latest drivers for your video card with the monitor plugged in the problem with you lcd is probably the ccfl went bad they are mini flourecent lights inside the lcd you need to dismantle the lcd then remove the old ccfl and solder in the new ones here is a link that sould help with the installation http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx
