Is there a way to turn off the LED backlight completely? Sending \014\000 still leaves some light and does not turn it off completely as indicated in the datasheet. This occurs with the light power connected to the 5V LCD and the separate 5V LED supply. Short of having a physical switch on the 5V LED line I see no other way of turning the LED off.
