The PD connector on the power board has 24 pins (2 rows of 12 pins, odd numbered pins in one row, even numbered pins in the other) so you need to check what voltage is on pin 24 i.e. the STB (standby) voltage. It's is hard to access at either end as it appears on PD 24 of the mainboard as well. - see image below. You may have to remove the cable and then check the voltage on the pin. ''Be careful that you don't short it out to another pin with the meter probe.'' The pin numbering is shown on the boards next to the connector

''Be careful that you don't short it out to another pin with the meter probe.'' The pin numbering is shown on the boards next to the connector
The STB voltage is usually about 5V DC. This voltage is used to signal the mainboard that the power is available and it is the mainboard that turns on the red standby power LED.
