I think most "electronic noise" is related to coil whine [1]. Although I can imagine that the hsync frequency of cathode ray tubes can cause audible noise. That would explain why you could hear CRT TVs but not CRT monitors. If you take the NTSC standard you can calculate ~15kHz for hsync frequency which is audible.

- whoopdedo 11y agoDoes the TV have speakers? Most do. You can get audible frequencies leaking onto the audio line and emitting noise. My LCD monitor has built in speakers that I never use and have turned "off", but every once in a while I hear a hiss from them.
