Unhappy [Q] Broken LCD and screen [GT-i9020T]

Hi,

I've broken my Nexus S. The screen is shattered and both the LCD and touch screen don't work. When I turn the phone on the bottom hardware buttons light up, there is the normal small vibration, however there is no display at all on the screen. The phone does seem to boot though.

Basically, I wanted to know whether buying and fitting a replacement screen, LCD and digitizer will fix the problem?

I have a friend who has replaced iPhone screen before and he seems to think that maybe it won't due to the screen not lighting up at all. Obviously I don't want to waste my money and buy a replacement screen for it not to actually work.

Thanks in advance!
