Are CRT TVs safe?
Color CRTs may contain mercury or other potentially toxic materials. If the CRT is broken or cracked, these materials may be released and pose a risk of toxic exposure. A charged CRT carries high voltage—about 27,000 volts in a color unit.
Why do CRT TVs smell?
The smell could be from the electrolyte of leaking capacitors. I recently solved that issue for some CRT front projectors manufactured in 1994. One day one projector would emit a mildew-like odor shortly after turn-on, and the smell would dissipate after about 5 minutes.

Do CRTs contain mercury?
Older cathode-ray tube monitors may contain up to eight pounds of lead. The lamp used to illuminate the screen is likely to contain mercury, and the coating inside the screen may be made from cadmium. Brominated flame retardants are commonly found in many monitor components.
What is inside a CRT tube?
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms (oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena.
