Lots of threads on tv and crt monitors. There is copper windings inside the tv and crt's. Also some Al. There is a dangerous electrical charge that can be held for a long time in side tvs and crt's.
One of our members Hoss does a lot tv and I mean a lot. Find Hoss and read all his threads from the beginning and you will have learned much of what you need to know. I recommend doing a lot of reading before you start tearing them apart.
The search function on this forum does not respond well to 1,2,3 letter searches and in "tv" or "crt". So if you have tried but failed to do a search on tv's don't feel bad.
Lastly there is no good reason to smash/break the tube in a tv or crt. Mike.
