Hello everyone!
I am trying to repair a power supply from the outdoor unit of an ac and i cannot identify a couple of diodes.
The one is the zener diode ZD17 which connects to the base of the transistor and another couple of diodes.
The other is a diode with blue dot that it is used all over the board.
The transistor is a 2sc3507.
Also the only think i can make on the zener diode is a very faint "A3" if that helps.
Thank you!
