(please note I'm not an electronics expert so please go easy on me!)
Daewoo TV model DTY-28W5GB, 18 months old. Nice easy circuit board to
pull out.
What happened was that I turned it on, and there was a crack, and it
was dead. I took the lid off and saw a blown fuse in the 250v part.
Found the correct fuse from Maplin, put it back in, 1 second after
turning on, CRACK! Fuse had exploded, and a small blue capacitor had
melted down and blown itself off the board, and apart.
There are other capacitors on the "low" side of the board looking
exactly the same as what this one should have looked like, and they
have (I think it says 8 or could be R+), then 471k below this then 1Kv
below that.
Nearby, there is a transistor package thing with 6(?) legs called an
STR F6653 SK4714 and a friend says it's often them that go too,
although physically it looks fine.
I've looked in the Maplin catalogue and can't find anything similar -
am I doomed from the start with stuff like this? It's just that
repairs are so costly these days, it would be cheaper to scrap it, and
that's just more toxic landfill, so I'd rather try it myself.
