Answer: Unfortunately, this sounds like a serious situation. When an evergreen browns all over it is possibly fatal. It might be the result of a pest or disease problem, or poor rooting, and/or possibly damage from winter deicing salts. I would strongly suggest you consult with your local county extension and/or on site with a professionally trained and certified arborist to determine what is happening and whether or not the tree can be saved. I'm sorry I can't be more specific for you long distance.
