PCA board servo rail not powered

Hey all! I'm new to working with servos, but I think I've isolated the no movement issue. I ran a code to check I2C response from my pico 2w: all good.

I used a multimeter to check voltage at the screw terminals: solid 5v.

Had a friend very fluent in coding check my setup: seemed fine.

However, when I plug in a servo, it doesn't move, including no horn resistance, so it's not stalled. I then checked with the multimeter on the actual channel pins, and there's no current.

Is my board junk or is there a simple solution? Can I just run jumper wires from the terminal to the channel pins and call it good? Help!
