I'm considering dissecting an old, color cathode ray tube television. Do cathode ray tube televisions have capicitors in them that could shock me?

Start with battery-powered circuits that you can bread-board. Radio Shack has bread-board kits with components that you can learn from. Learn the functions of the components, how to read the values of those components from markings, how to measure the values using a digital multimeter, etc, etc. Before you delve into AC or high-voltage DC circuits, you MUST learn how to test and safely discharge capacitors. They can kill you.stickythighs said:What is a safe place for an amateur to start?

You could get some damage playing with something like that, but you can also discharge capacitors with a resistor (~50-200k Ohmms value should be fine) connected to two wires.stickythighs said:I'm considering dissecting an old, color cathode ray tube television.

A cathode ray tube television, or CRT TV, is a type of television that uses a cathode ray tube to display images. It was the most common type of TV until the rise of flat screen TVs.
In a cathode ray tube television, an electron beam is produced by a cathode and directed towards a phosphor-coated screen. The beam is then controlled by electromagnets to create images on the screen.
The main components of a cathode ray tube television include the cathode, electron gun, deflection coils, phosphor-coated screen, and electron beam control circuits.
Cathode ray tube televisions have been largely replaced by flat screen TVs due to their bulky size and high energy consumption. Flat screen TVs also offer better picture quality.
Yes, there can be risks involved with dissecting a cathode ray tube television, such as exposure to high voltage and potential release of toxic substances, such as lead and mercury. It is important to take proper safety precautions and dispose of the components properly.
