hi there i am learning my self since a lot of time...

i am measuring output voltages of the power supply(internal) on one monitor.

The board is 715g2892-2-3.

I see on heat sinks only one Q and one diode - D906.

How to understand which is the other rectify diode ? i have 5 volts on D906. the one i see in big housing is D902 but there are 16.24 volts that are not so close to 12v. in the photo in guide i see 13.68 which probably seems fine without load.

Thanks
