If it's a 3.2v I believe the test point you are checking is the LDO power supply that's the normal value. Also, check its resistance if it's shorted or has abnormal resistance.

If I were you don't go directly to hardware better start to diagnose the issue through the miner's logs and it might be just a PIC program issue. Replacing it with working PIC file should fix this issue you can get the PIC file from other known working dashboard.
