We've also opened the DSC in question, but there is no noticeable damage to it. Here it is: 
If you'd like, we could send it to you so you could take a look at it. |
Looking closer at the left edge of the board it appears that the resin has melted. We occurred similar issues last year and damaged 3 DSCs before locating the issue. By having the power and signal wires reversed on our pressure sensor we were sending 5V "the wrong way". In one instance the voltage was enough to desolder some of the contacts on the board. If the resin looks wavy and non uniform you have a definite wiring problem.
