Z4000 IS NOT WORKING .

Hi Guys

I have two Z4000 transformers, which I bought about 08 years ago. Both have worked well, so far, but today one of them stop to work. The problem is the following:

when I turn on the transformer, I read on the meters: Left side 40V and 0.0A; Right side: 0.00V 22A. I understand that this is a normal condition.

After about 20 seconds, the panel turns off, the fan stops working, however the auxiliary voltages 10v and 14v continue working.

I disconnected the transformer from the circuit and turned it on empty on the bench work. Same condition

I wonder if anyone has ever detected this type of failure and can guide me what to do.
Just for clarification, I live in Brazil and send the transformer for repair in the United States will be very difficult.

I am an electronics engineer and maybe with some "tips" I can solve the problem. Thanks in advance for your comments
