Look again. The only thing that is getting 24V is the cRIO. The Solenoid Breakout can either take 12V or 24V.

To me it looks like they have the 5V output from the PD board connected to the digital side car. That would cause an issue. Even though the LEDs are lit (minus the 6V one), they wouldn't have enough voltage to drive the various chips on board to enable the PWM output.

I also agree with the ribbon cable posts. Those things are trouble.
