    Hello,

    I repaired a power supply. I found a diode in short-circuit. I would like to know what sort of diode it is. I can read 7777 on the diode.

    Thanks in advance for your help.

    Hello,

    I attached a picture on wich you can see the major components near the diode.
    The sub-board control the H-bridge.

    Ask me if you need more information.
