Hi,

Thanks for providing this schematic!

From Page 21, we can see that VCC3P3 signal is controlling the 3.3V Power LED D6.

To understand which component is defected, you can measure some point's Voltage to GND.

VCC3P3 Test Point Pad,

R57/R60 both sides to GND (Measure the voltage to ground at both ends of the resistor separately),

R184 both sides to GND,

L12 both sides to GND,

R47 both sides to GND.

I think by checking these points, we will at least understand which component is defected.

Best Regards,

Xiaoyan
