NEC FS6390

[Newsboy]

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.

The blown off part is labelled STR S6708 SK5N18.

** WES Components in Ashfield sell them - for circa $20 each inc.

Phone (02 ) 9797 9866 and pledge your plastic.

Lots of Luck !!

Okay, I've answered one of my own questions ! De-soldering pumps and braid !

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 !

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