Dead backlight on laptop screen.

I found out that my household laptop (protege x30wj) had been dropped and now the backlight of the screen is no longer working. The screen itself is fine: it displays fine and it responds to touch as normal. The keyboard's backlight is working.

I tried looking at my local market (Australia) and found no easily accessible screens replacements.

So, I got some questions:

Can I use a 13.3" IPS touch screen assembly that's designed for a different model of laptop, on my dynabook?

If not, is it worth trying to take the assembly apart? It requires tools like heat gun, right?
