Can't get to the TV core!

There's always the option of taking a pass on the ones that give you a problem.

The picture tube is under a vacuum. You have to be careful working around the end of the tube because if you break it the picture tube can implode. Then ... you've got shards of glass along with lead, and mercury that have contaminated your workspace.

All of that mess to clean up for maybe a pound of copper ?

Doesn't seem like it would be worth it.
