Q.No green leaves from my miscanthus ornamental grass. Is it too early, or is the plant dead? Will it still be alive and produce new
growth? We cut it back in middle winter. Is it still alive? Did not see new growth;only brown leaves.

You should see new growth in early spring. Pull out some remaining dead grass in clump. Still don't see green? Typically, they are cut back in late winter or early spring, but I doubt that cutting it back in mid-winter would have killed it. They are generally tough plants and not prone to disease.
You are in zone 6a, which is appropriate for miscanthus grass. Did you have an exceptionally cold winter? Perhaps excessively dry too. It sounds like, for whatever reason, you did lose it over the winter.
