    Hello,

    I bought an iMac 2009 but it is missing the LCD temp sensor. According to the pictures that I have seen it is a TO-29 Transistor looking component that is the LCD sensor. Does anyone know what is the transisor number so I can buy it from digikey or elsewhere?

    Thanks!

    SOLVED: A1312 LCD Temp Sensor; what resistor is used

    No answer here or anywhere so I ended up forking $20 on this. But to help others, here is are the numbers on transistors (and it can be bought from digikey for 19 cents ($0.19):

    2N
    3904
    B331

    Number that helped me find it on digikey was 2N3904. the right two legs are shorted. See the picture.

    Take care,
