    please help identify this diode

    im working through my tv power supply board and i found a diode which appears shorted.the best way i can describe the diode is clear glass/plastic with a single yellow band.i have tried taking pics but cannot focus in clear enough.

    Doubt if there is a chance better to post a picture of the board it came from with a close up of where it is and the board designator ZD??? can you find a schematic?

    There is no fixed marking agreed between manufacturers the yellow band just signifies cathode ( If I remember correctly)
    Please upload pictures using attachment function when ask for help on the repair

        It may be connected in parallel with a low ohm resistor.
