If one socket is working, then the diode is good. Thers is only one diode that I can see in the photos.
The charger is a crude half wave rectifier. The output of the the adaptor is AC (9Volts), therefore the diode rectifies half of the AC wave to give you a crude DC voltage which is likely smoothed out a bit by the caps and current limited by the resistors and, of course, the battery.
Did you check for voltage right on the board contact points? I ask this because I'm suspicious of the platic case and it's contacts perhaps not mating properly at the board.
