What's Inside a TV - Dissecting a Sharp CRT Television - Parts 4 Salvage

How to get FREE project parts like copper, speakers, wires, components and so much more from a TV. In this video I walk you through the deconstruction of a Sharp CRT TV, provide some important safety comments (see more info below) and point out some of the key items that I like to salvage for future projects. If you like DIY, recycling stuff, re-purposing materials or merely like to take things apart, then this video is for you. There are plenty of free materials to be had from old, broken or unused electronics and with a little caution and effort you can get a good haul of loot to use. In a previous videos I walked through the deconstruction of a Sony TV and a JVC TV. Each has some uniquely different parts. Links to those videos:

Just for fun there is also some explanation behind the Electron Gun, Copper Yoke, Degaussing Coil, what "CRT" means and more.

In this TV autopsy the items I salvaged include the following:
Capacitors
Copper
Copper Yoke
Degaussing Coil
Diodes
Flyback Transformer (Warning: can hold a potentially lethal charge for a long time)
Fuse
Hardware (screws, washers, nuts, etc)
Heat Sink
IR Receiver
LED

These CRT TVs are pretty cool. The electron gun (the part sticking up from the back of the picture tube) creates a stream of electrons that flow through the tube. Coils of wires operate as electromagnets to guide the beam to the precise points on the screen which is coated with phosphors. When the electron beam hits the phosphors they fluoresce and create the image you see. All of this requires a well controlled internal environment including a glass "tube" full of lead, phosphors and more which is under a significant vacuum pressure. If you are not careful, then you could cause the tube to implode which could be quite dangerous. Remember to recycle responsibly especially for the electronic components and the TV tube itself. I take all left over electronic parts and TV tubes to a local electronic salvage company that takes everything free of charge. Taking things apart (or deconstructing items) not only gets you great free materials for projects but also helps you learn about how things work. In my series of "What's Inside" videos I typically show how I take things apart, how some of the parts work, options for fixing some items and sometimes I just tear things down to get to the good parts so I can upcycle or repurpose the original item. It's allot of fun!

WARNING: working on electronics carries certain risks. If you deconstruct a TV, then you are doing so at your own risk. While I mention some safety considerations in the video you really need to do your own research to ensure that you are fully informed and comfortable with what you are doing. Choose the safety techniques that work best for you. If you have never worked with electronics or dismantled electronic items before, then a TV is not a good first project. Start smaller and build knowledge and confidence so that you know how to remain safe! You are responsible for any outcomes that result from trying to duplicate anything seen or heard in this video.
