All you gotta do is mess up a TV and cut it out. http://www.instructables.com/id/How-to-take-apart-TV/.
-=please dont comment on the dangers of taking apart TVs and such, that is discussed in the link above. this Instructable has nothing to do with taking apart TVs just an extra thing to get out of a TV when you take one apart=-
Step 1: You will need
a pare of scissors,
a wire spool
and a chair to sit down in and relax for a while.
as well as the wire!
Step 2: Unwind the tape
The tape usually starts where the two wires go in or sometimes about 6 inches down.
You may want to upload a YouTube video before you start because its going to take a long time!
If you want to keep the tape you could wrap it around a pencil or something.
use the scissors to cut excess tape and the two main wires but DONT cut the magnet wire!!!
Step 3: Unwind the copper
do it however you want, i put the wire over my knee and turned it and wrapped at around the spool.
As you can see Im not very good at winding the wire but thats cause it takes much to long to do it neatly.
Different TVs will have different gauges and colors but i like the red wire best.
