Recently I am testing the latch fault by removing the LED connection cable. All 6 LED_FAULT bits, the OPEN_LED bit and the LED_STATUS bit in status register 2 becomes 1, so I assumed I entered into latch fault. Is this correct?
Then I insert back the cable so that the connection is back to normal. No backlight is seen, so I assumed I am staying in latch fault state.
Now I am trying to escape from this latch fault. I tried toggling the EN line (pg.36) but nothing happens. Why is this so?
