The complaint device was returned for evaluation.Incoming visual inspection identified that the case was cracked.Technical visual inspection found that the screw posts on the bottom case were broken.Device evaluation confirmed an issue because the device failed the ultrasound transducer electrical check.It was determined that the power board had an integrated circuit failure, there were loose crystal, and several damaged components on the main board.Three loose crystals were re-secured, internal capacitators, resistors and amps were replaced, and the top and bottom cases were replaced.The parameter, cable, crystal, and shake rattle tests were performed and passed.A definitive root cause could not be determined for the loose crystals, damaged capacitors, resistors and amplifiers; however, due to the case damage these are most likely due to the device being dropped and/or mishandled.This type of event will continue to be monitored.
