So you claim that pretty light TV pictured actually weighs 500lbs
Nor do they have 1200W transformers in them.
As a TV service engineer for over years I've carried plenty of them - FAR lighter than much smaller CRT sets.
It's not something you see too much of in Europe though, the poor picture quality and abysmal viewing angles from them meant people weren't very interested.
Nor do they have 6" thick wooden 'walls'
Perhaps you should learn not to exaggerate everything you claim - it makes you look rather silly
Obviously what you can sell something for is dependent on what idiots will pay for junk, but of what use is the mains transformer in the picture you posted? - presumably it's got useless winding voltages?, so not much use?.
