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 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?

Thanks.
