One of the leds is not lighting up

Hi, I am using pynq z2.

The attached photo below shows the board reading the SD card after turning it on. You can see that only 3 LEDs are lit.

Just in case, I compiled it to light the LEDs, but led0 doesn’t light up either.

It’s not a critical problem, but I’m using the LED for debugging purposes, and I’m a little confused because led0 doesn’t light up.

Is there a way to fix that?

It looks likely the LED on the board is faulty.
