The device referenced in this report was returned to olympus for evaluation.The subject device was powered for an hour, and the power was turned off and on, then the reported event was duplicated.Though a water leak test was performed, the leakage was not found.The manufacturing record of the device was reviewed without irregularity.The exact cause of the reported event could not be conclusively determined, but from the past evaluation, it is surmised that the circuit board of the video connector is broken, or starts to be broken.Since the sealing was applied on the circuit board of the video connector, further analysis, such as confirmation of the mounting parts, could not be conducted.If an overcurrent is applied to electrical contacts of the video connector due to such a phenomenon as electrostatic discharge, the mounting parts in the circuit may be broken.

The user facility used the subject device for an esophagoscopy procedure.To change the patient body position, the scope was withdrawn from the patient and the power was turned off.After the position change, the power was turned on, but the endoscope image did not appear, and b32 error (scope malfunction) was displayed.Though the user facility reconnected the scope, the error was not reset, so the subject device was replaced with ltf-s190-5 and the procedure was completed.There was no patient injury reported.Even when the subject device was connected to another video system center, b32 (the endoscope is damaged) error occurred.
