UCD9080 EVM No Outputs

Part Number: UCD9080

I have a UCD9080 EVM.   Powered up the EVM with +5V.  Red LED D4 illuminates.  TP12 and TP11 are 3.3V.  Problem is no outputs TP1 thru TP8.  Checked enable pins of regulators.  Being held at approx. 1.6V.  LEDs D1- thru D11 barely illuminated.  Forced a few enables to ground and outputs were present.  Question is what is holding the enable pins at 1.6V?  This happens with EVM connected to PC or not.
