    Failed MOSFET - double checking and getting a replacement

    Hi guys

    I am current relearning my old skills from days gone by so what to make sure I am doing this right.

    I have PSU Board in front me from a TV I am current working on - I am wondering If I have this right

    I have tested fuses/caps and these are all okay and focus has now come to the MOSFETS on the board - I have 3 (2 are the same) - AOD452A
    http://www.alldatasheet.com/datashee.../AOD452AL.html

    If I have +ve on the gate and -ve on the drain I get a reading from both of them

    If I put -ve on the gate and +ve lead on the Source I get a reading from one but nothing from the other - is the one not showing a reading a shorted part?

    Best to remove them from the PCB and test them they are not easiest things to check best to use a dynamic circuit.
