is the LCD that is cracked or its the window that protect the LCD?
if is the window, replacement cost is cheap. you can even choose not to remedy it since it does not affect anything. If the LCD needs to be replaced, cost will be on the higher side. whatever the case, its best to give NSC a call.
it is the inside LCD so yeah.... going to give a call on monday since their call center only open from monday to fridays. just post here to see if anyone encounter before...
