Sorry – without being there there is nothing more I can tell you. I would suggest you find another way to do what you need, or hire a local technician to take a look.
If your Eclipse is still under warranty you should send it in to be checked, otherwise support@eventide.com.
My guess is that the Eclipse is fine, and there is something in your setup that is causing the problem. But, I could easily be wrong.
One thought – can you use AES instead – this is usually more reliable.
