Instructables
Picture of What can you do with an old TV?
In this Instructable I will show you several easy ways to recycle and reuse the expensive components inside a TV. There is the PCB (not very useful), a lot of inductors, one or more transformers, a TON of magnetic wire (continuous and insulated), a screen (can’t use either) and heaps of components on the PCB that will save you a lot of money. This Instructable probably doesn’t work with LCD TVs.

WARNING: most TVs especially CRT's can hold a very high voltage for days. You should Discharge any capacitors on the circuit boards before going ahead and removing anything. To discharge a capacitor simply place a well insulated screwdriver across the terminals, if its holding a voltage you will get a spark. Or you can just bridge a large resistor across the terminals. And also, unless your very confident around high voltage and have a good knowledge of TV's, it’s a really bad idea to plug the TV in whilst the cover is open and go poking around.

cool ible. i like your bio: "My hobbies are electronics, pyrotechnics, chemistry and making cool stuff."

it might be a good idea to mention the PCB can hold enough charge to knock out or even kill you.

when i see a old crt tv on the side of the road i take it home take out the pcb in the back and the electorn gun off the back of the crt but first i have to discharge what voltage is left in it and break the vaccume so i dont kill myself and take off as much magnet wire as i can i also take old crt computer moniters i see on the side of road and do the same thing.
guys this is my new account, so please subscribe. my old account is glitching
ill put these instructables up so you'll be able to see them

It Might be worth mentioning in your Instructable that most TV's (CRT's especially) can hold a very high (if not lethal) voltage for days.

You should Discharge any capacitors on the circuit boards before going ahead and removing anything. (to discharge a capacitor simply place a well insulated screwdriver across the terminals, if its holding a voltage you will get a spark).

And last but not least unless your very confident around high voltage and have a good knowladge of TV's, its a really BAD idea to plug the TV in whilst the cover is open and go poking around :)

Hope this helps.

thanks for the feedback.

i used very very old TVs so i didn't encounter those problems.
