If TV CRTs are anything like computer monitor CRTs they can't be broken, at least not in any Im/Ex-plosive way. We used to throw them in the dumpster all the time and we couldn't get more than a "whoomp/crunch/hiss" sort of thing. They have a plastic membrane in the glass like a windshield. The thing just becomes a bag of broken safety glass ... after lots of abuse.
