After a bit of discussion with Aleksorsist, she mentioned having ultrasonically cleaned the board prior to sending it to me. Sonication of MEMS and oscillators is risky due to the potential for floating structures to resonate at the frequency of the applied ultrasonic energy and be damaged, so I recommended not sonicating future ThunderScopes regardless of whether it ultimately turned out to be the root cause of this device’s failure or not.
