If it haven't been touched, you can still try to contact bitmaintech for an exchange.
As for finding where it could come from, I'd suggest checking the voltage between any ground and the output of the 4 big square coils.
You should read something like 1.1v
There is also the U35 chip that gives 3.3v at the output of the small coil named "L5" next to the ribbon cables.
I'm not familiar with the S1 yet, I got my first one a few days ago, but the hashing boards are all more or less the same and made of 2 things: -Hashing chips -Voltage regulators
The voltage regulators and electrolytic capacitors are often the culprits for non working material
