The reported complaints that "a clicking noise was heard upon powering up the autopulse platform (sn (b)(6) ), and the lcd screen was blank" were confirmed during a visual and functional inspection.The lcd screen was observed blank due to the malfunctioning lcd transmissive board.This was caused by a failed processor board, which prevented the platform from powering up.The processor board (pca) failure was likely attributed to the age of the device.The autopulse platform was manufactured in july 2013 and is over 10 years old, well beyond its expected service life of 5 years.The platform was further examined, and it was noted that the power distribution board revision level was below 6 and needed to be updated, attributed to the age of the platform.This observation is unrelated to the reported complaints.An archive review could not be performed because the data could not be downloaded due to the failed processor board.The initial functional test couldn't be performed due to the blank white screen and continuous clicking noise at power up, confirming the reported complaints.The malfunctioning lcd transmissive and processor boards must be replaced to resolve the issues.The customer declined the service repair.This platform remained unrepaired and was labeled with "not for clinical use".Historical complaints were reviewed for service information related to the reported complaint, and there was no previous history of complaints reported for the autopulse platform with serial number (b)(6).
