CRT Television Power On

How it's made

Source

a latching power switch excites a plastic cabinet; a decaying 60 Hz degaussing current produces a blunt magnetic thump with 120/240 Hz magnetostrictive buzz and low filtered turbulence.

Body

cabinet modes near 175, 410 and 930 Hz decay in 65-180 ms; larger cabinets lower these modes. The switch has a 0.7 ms rounded noise onset, a 3 ms contact burst and a weaker contact bounce.

Envelope

degaussing rises in 9 ms and collapses over 0.35-0.55 s. High voltage builds after 0.10-0.38 s, with a short overshoot before locking; an editorial 200 ms fade ends the 1.5 s shot.

Layers

flyback vibration settles within 1 percent of 15.625 kHz, with a much softer mechanical half-frequency component and 60 Hz supply ripple. No above-Nyquist harmonics are synthesized.

Events

charging glass releases 0.6-4 ms filtered noise grains, 110/s initially falling to 3/s; a changing 1.4-6 kHz hiss briefly blooms and decays independently of the degaussing body.

Variation

seeded contact bounce, cabinet tuning, discharge timing and whine drift vary subtly. Macros set cabinet size, degaussing weight, static, whine and voltage rise time; presets cover a small portable, a bass-heavy living-room set, dusty crackling glass and a restrained warm start.
