hi folks i'm new to this forum and have a question . i have a sylvania
srt2127s that blows the fuse as soon as i plug it in. I just started
messing with busted tv's as a hobby because i recently had surgery for
a work related accident and needed something to keep my mind and my
hands busy. I just fixed an old sanyo that just needed a couple of
capacitors and now i'm trying my luck with the sylvania.please talk in
layman's terms as i am not tech educated. pictures or diagrams of parts
to check or replace would be very helpful. thanks,wish me luck!

Hi,
Your description indicates a "primary-side" failure, in other words,
the side which is not
galvanically isolated from the mains and need great focus to not kill
yourself during repair.
A wild guess, would be a shorted input rectifier or a shorted
switching transistor in the TV's switchmode powersupply.
I've even seen damaged mainscords with internal shorts! Maybe a dog
chewed on it. This would of course lead to a fuse blow before pressing
mains switch on the set.
I'm not familiar with this specific set, but that's general TV tips.

Good luck!

Well assuming he's in North America, the mains plug is not fused. The
only circuit protection we have here aside from the fuse in an
individual piece of electronics is the 20A breaker on the branch circuit.- Dölj citerad text -

I believe he means the internal fuse in the set, don't you think?
