    STR - Y6476 testing

    Hi there wondering if someone could tell me if its possible to test the above component out of circuit using a multimeter.i have removed it from the power supply board of my lcd tv as there was burning around the legs on the back of the circuit board.also where is the best place to get a replacement in the uk.
    thank you.

    thats a power ic,these normally fail VCC to ground,just identify the legs from datasheet,you want to see high resistance between the 2 legs (vcc and ground)
    fixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!

        also burning like that can be due to cracked solder joints,seen it a million times,turning the light off and flexing the board with an insulated tool may show it up as a spark.
