You could send it in to Dynatek(address listed below), however, call Larry Nelson first. Be patient as he is a one man show and if your box is determine defective, they will replace it with a new one for $123, much less than the cost of a new one at $285.
However, again you need to be patient as this process may take 2-4 weeks.
