In units with serial numbers in the ranges of LFTRNWAN3800001 to LFTRNWAN4805300 for Model E601i-A3 and LFTRNXAN4500001 – LFTRNXAN4702936 for Model E701i-A3, users may experience a loss of video on the display although audio can still be heard. This issue is attributed to a limited batch of chip assemblies from a supplier, in which there is a small percentage chance that the chip assembly prematurely fails; this causes the timing control board to be disabled, which disrupts the video signal to the display. This potential issue appears to occur typically around the first 500 hours of usage or first few months of normal usage and does not present a safety concern.
