(b)(4).Device evaluation by manufacturer: field service engineering visited the customer to address to address the reported event.Fse was able to confirm the error.During further troubleshooting, fse suspected that the issue was related to power supply since the main circuit breaker had been tripped.Fse replaced the 12v switching power supply and the main circuit breaker was no longer tripping.Fse then found that the lcd touch function failed.Fse reloaded the software but the lcd touch screen was still working sporadically.Fse replaced the lcd screen, reloaded the software, and the touch display was working without any issues.Fse ran precision, calibration, and quality controls (qc) with acceptable results.Fse found that the column count was >2500 injections and advised the customer to replace the column after 2500 injections.The customer declined stating that they use the column up to 5000 injections as long as the qc values and pressure are within acceptable ranges.A 13-month complaint history review and service history review for similar complaints was performed for serial number (b)(4) from (b)(6) 2017 through aware date (b)(6) 2018.There were no similar complaints identified during the searched period.The g8 variant analysis mode operator's manual under chapter 3, assay operations, states the following: if the main power switch is turned on and the screen does not display, or if an error is displayed, or some other event prevents the analyzer from activating the warming up sequence, turn off the main power switch.If the analyzer still doesn't start, contact technical support.The most probable cause of the reported event has not yet been determined.The investigation in progress.
