Device evaluation of monitor sn (b)(4) has been completed.The problem (screen flashing) was confirmed.As received, the monitor would not fully power on.Upon evaluation, the monitor exhibited a flash memory failure at bga components u102 and u105 on the c/a board.Root cause investigation into devices exhibiting similar failures modes indicates likely intermittent bga connections.The intermittent connections are likely induced by mechanical stress.The exact source of the mechanical stress has not been positively identified but the intermittent connection may have been accelerated through rough handling.No adverse event resulted from the defective monitor.
