    Hi All,
    I've inherited a blown FS 6390 NEC television off the in-laws, I can
    tell a few of you will delete now ! If not, I have popped the cover and
    traced the power, 240v in and the fuse is ok, found a blown area in the hot
    side of the circuit board, but the main problem looks like an item attached
    to a large heatsink that has blown, I've been having a bit of a google and
    can't find too much, can anyone help with a site that may have circuit
    diagrams or info ? The blown off part is labelled STR S6708 SK5N18. I found
    one place in the states that sells them in bulk but they don't name it ! I
    have some digital pix of the areas if anyone would like to volunteer to
    advise remotely ! The part has many legs soldered to the board, so that begs
    the question, how the hell do you remove it ?
    Any help or pointers greatly received as having read the TV serviceman
    section in EA, I know they are a trying mistress.
    Thanks,
    Steve.

    Thanks Phil, what is the part actually ? a resistor or something ? I 'm
    proud to say that I know which end of a soldering iron to hold !

    ** The number alone gives little clue as to what it is - for that you need
    a schematic or the set to inspect.

    But if you need one - you now know where to go.

    Steve, it's a switching regulator. Given that you mistook it for maybe a
    resistor, you probably don't want to hear that it's probably going to blow
    again when you replace it. Watch out for big voltages (and big bangs).

    I'm reminded of the old expression about "shooting ducks on the water"....
    it really isn't sport, Phil. :)

    Thank you ! I'm a network technician, so I'm used to seeing the magic smoke
    escape from equipment from time to time ! I also have a very healthy respect
    for 240volts and also for capacitors !

    Too much spare time on your hands Bro?

    Given that you can't recognise the difference between an IC and a
    resistor, I'm wondering what a capacitor looks like to you. ;-)
