On the fire issue in almost 40 yrs of TV repair I have
never seen a set go into open flame burning. We saw
plenty of dried up junk but never a fire. Things burned
but it always was limited. FBT's & triplers could be
spectacular but it stopped there. Resistors glowed white hot
& smelled like dog doot. Rooms filled with acrid smoke.
But never a real fire. Yes you could light your smoke
on it.
Bottom line is just dont leave things old running when you
go. Just like burning brush. Use a little common sense.
The crude extension cord isnt much of a risk. They do
have a voltage drop so a little heat. Feel any cord moving some
watts & it will get warm.
