taking apart a TV
January 27, 2009 10:48am CST
I have an old TV that I have taken apart, I want to use some of the wire and components to recycle and make things from. THe TV has been unplugged for about 2 and a half months now. Is it safe to cut the wires? I'm not gonna touch the bulb or the bowl, but I want to make sure its safe to cut the wires.

TV's have some parts that carry very high voltages. Often these are stored in large capacitors and can remain dangerous for a long time, depending on the circuitry. I would have thought that 2 months or longer would be enough but it's impossible to be sure. Better to be safe than sorry! You can short out these components with a screwdriver or a well insulated piece of thick wire, when they will become safe to handle. Be very careful not to break the tube. It contains phosphors which can be harmful. You should take it to your waste disposal site to be disposed of correctly and safely.

Cut the blue wire! No, the red wire! TV repair men will quite happily open up a TV and stick a screwdriver into it about ten seconds after it's unplugged. Now I'm not handyman, but unless there's electricity running through it or you're breaking open components, I don't see a problem. Wires are just wires. Bits of metal. I know I wouldn't worry, but then I don't know exactly what you're doing, so I'm a little less confident than if I were standing there encouraging you to electrocute yourself...
