Sony Vaio T Series LCD screen replacement

Hello,

My Sony Vaio SVT13128CXS ultrabook display stopped working all of a sudden. When I connect it to an external monitor, I can see the content on the external monitor. And if touch my laptop touch screen, I can see the effect on the external monitor. How do I fix my lcd screen. Any ideas?

Looks like I need to replace the lcd screen. Any idea where I can find the right parts. Also are there any tutorial videos available to replace my LCD screen?
