LP8863-Q1: SD pin

Part Number: LP8863-Q1

Hello ,

We are analyzing the cause of the LED driver not functioning.

I am observing a waveform at the SD pin that regularly wobbles from about 3.3V to about 12V. What is the cause of this phenomenon?

As for the others, the circuit is operating normally, except that the backlight does not turn on.
