your sod is not green because it is dead. death is the final stage.
there is no future for it. it is dead. it will not recover. give it up.

I started laying my sods about a week ago.Due to rainy weather, I
could not put all the sods within a day. As a result, I put some of
sods after 3 days from time of delivery. Although the sod was not
dired out, the blades were not green. They looked dried. When I put
these sods, I have been watering these guys since then. However, I
cannot see any sign of recovery. Should I wait more, or the grass is
dead?

thanks
