During preventative maintenance on (b)(6) 2024, the display of the autopulse platform sn (b)(6) was readable but showed lines through the display.The root cause was due to a failure of the lc display, likely attributed to the age of the device.The platform was manufactured in 2013 and is over 11 years old, past the service life of 5 years.During visual inspection, the front and bottom enclosures and top cover were observed to be cracked/damaged.The observed physical damages appeared to be the characteristic of user mishandling.The front and bottom enclosure and top cover were replaced to address the damage.The lc display was readable but showed lines.The display was replaced to remedy the issue.The archive data showed user advisory (ua) 41 (patient surface temperature sensor malfunction) error message, unrelated to the lcd issue.The autopulse platform passed initial functional testing without any faults or errors.The platform passed the load cell characterization test without issue.The (ua) 41 seen in the archive could not be reproduced during functional testing.Nevertheless, the temperature sensor was replaced as a preventive precautionary measure, as there may have had some intermittent technical problems that could not be directly identified during the functional testing.Following service, the autopulse platform passed the run-in test without any fault or error.The autopulse platform passed the final testing without any fault or error.Historical complaints were reviewed for service information related to the reported issue and there were no similar complaints reported for autopulse platform with sn (b)(6).
