I'm repairing a Playstation 2 power supply model 1-468-604-21. I've found
the D016 zener diode to be shorted. This is a very small zener diode and
the only numbers written on it are 2, then elsewhere 1 0 and finally a B.
This is the only one marked like this. So I cannot test its value from a
good one. Does someone knows what is its value or replacement part number?

Thanks.
