But how can one board not be faulty when under the EXACT same settings, one passes and the other one fails?
The one that's failing has to be faulty one way or another. At the very least, in the auto-voltage regulation, no?
1) Do I keep the board with a faulty temp sensor?
2) Do I keep the board with a faulty auto-voltage regulator?
3) Do I return both and get a 3rd one (and risk that one having some other fault)?
What do I do?
All opinions are welcomed. Thanks.
