Physio-control evaluated the customer's device and verified the reported issue.Physio then replaced both the system controller (sc) and user interface (ui) pcb assemblies and completed other, unrelated, repairs.After observing proper device operation through functional and performance testing the unit was returned to the customer for use.Physio further examined the removed ui pcb assembly and determined that the cause of the reported issue was an electrically shorted integrated circuit (ic) chip, designator u8.The sc pcb assembly was an ancillary part and there was no failure of the assembly.
