Answer
Since we do not know what caused the grass to die in these areas, check that the sprinkler system is covering the whole lawn adequately. If it is, then cut out the bad spots to a depth of about 6 inches. If you do not encounter any harmful insects, replace with about 3 inches of clean topsoil and sod over. Water in and water the new sod by hand to prevent it from drying out and to avoid overwatering the rest of the lawn.
