    I have a sharp microwave oven model #R-310FW.
    Q1(SMD Txistr) on the display board is smoked.
    Anyone know what the part # is
    or what it is (IE: NPN,PNP,FET)

    Is it a common failure in/on this model?

    You will need to experiment with this item unless someone can supply a board
    with a known good device. Sharp will not supply individual components,
    and/or part numbers for these boards, they recommend replacing the complete
    controller assembly. What a bite!!

    I paid $17(USD) for the microwave and the new display board costs
    The schematic and parts lists will cost me $20.00
    Now that I have that rant off my mind,
    There are several web sites that will sell me a schematic for a sharp
    And they claim to have individual part numbers and cross references in
    the parts lists.
    I find it crazy that these web sites claim to have the info and NO ONE
    ELSE DOES???

    I guess it's back to reverse engineering the transistors function to
    determin a good replacement.
