You would need to find Toshibas "Dead Pixel Warranty" to find out what your rights are it should be in your Toshiba warranty definitions that came with the pc, it is no way vendor related, they can not impose their own version of it.
For the record:
Black pixel = dead
Coloured pixel (RGB) = stuck
There are software programmes you can use to try and "unstick" stuck pixels also you can either gently massage stuck pixels or gently flick the stuck pixel to try and unstick them.
NOTE: You try the latter two at your own risk
Whilst the warning sounds ominous I have actually unstuck a pixel using a combination of both methods.
