Default Ned Trouble Shooting Advice - Suspect ES9018

Question for Russ: I have documented my Buffalo III problem on your support Forum, See: Twisted Pear Audio Support>>Product Support>>Digital>>Buffalo DAC>>Minor Issue With LED on AVCC Module. On the TP Support Forum you asked me to post photos of the Buffalo III board without AVCC module both sides of Buffalo III. Have not had any response or advice from TP since posting photos on the TP Support Form thread, a week ago.

Summation of My Present Problem: Buffalo III had two new fresh AVCC Modules installed and both AVCC Modules have had D1 stop working within one minute of operation. This is a new build, still in the turn on stage no hours. Needless to say, this Buffalo III is not going into Lock until I solve this problem.

Question: From my perspective I believe the symptoms point to a faulty ES9018. I need trouble shooting advice from the man behind the product design. Assuming the ES9018 is still O.K. - How do I determine this ES9018 device is O.K without causing any damage to the device? If the ES9018 is not O.K. - What are my alternatives if this ES9018 has a problem?

You can simply provide another 3.3-3.6V power supply to the left and right AVCC out pins - with the AVCC modules removed. A bench supply is good for this type of testing.

Check that the two sides are drawing the same amount of current.

If the DAC works, then the ES9018 is fine.

My guess is that the same thing killed both AVCC modules. What is powering them?
