The reported complaint that the lcd screen of the autopulse platform (b)(6) was blank was not confirmed during the visual-functional inspection.No problem was found, and the autopulse platform functioned as intended.Visual inspection showed a vertical crack going through one of the screw fittings of the front enclosure, unrelated to the reported complaint.The observed physical damage could be attributed to wear and tear or user mishandling, such as a drop.The autopulse platform was manufactured in (b)(6) 2013 and is over 11 years old, well beyond its expected service life of 5 years.The front enclosure was replaced to address this issue.Reviewing the autopulse platform's archive data didn't show any significant discrepancies or error messages.The autopulse platform passed initial functional testing without any fault or error.The autopulse platform was tested with multiple known-good test batteries, and the platform's on/off power button was pressed about 10 times.Each time, the autopulse platform powered on with no issues, the lcd screen was clear and the parameters on the screen were clear and readable.The lcd screen connector and all the wiring cables were checked, and no issue was found.Subsequently, the autopulse was subjected to a run-in test using instrumented manikin and large resuscitation test fixture (lrtf) for approximately 15 minutes each, and the platform passed the tests without any issues.Zoll is awaiting the customer's approval for repair.
