Famous stuff this

There was significant research done in '76 on this.  It's called floobydust. It was in that year's NSC Audio and Radio handbook [1].  It is featured prominently in latter day Dorkan Encabulators as a new form of energy.  The digital version is alternately known as Kruft and serves as a topping for spaghetti code.  Sometimes, floobydust is used by SW folks, but it's really a hardware thing.

hope this helps.

Did the owners smoke?

I used to work in radio and TV repair shops in the 1960s.  The only TV sets that came in with that much dust were from homes in which people smoked.  The smoke particles added to the dust, and helped make it stickier.  Most all TVs from the 1960s and later had bonded faceplates, so no dust could get between the surfaces.  But it always took a lot of extra time and trouble to remove the CRT from an older TV (from the 1940s and 1950s) to clean the inside of its faceplate and the front of its CRT.  I could always easily identify homes with smokers because of the sticky (and hard to clean) yellow film that covered the glass surfaces.  I could never understand smoking anything, because it would be exposing our lungs to similar accumulations of dust and dirt.  Ugh!

The ability to collect dust was a FEATURE!  Sort of a low tech natural way to provide air quality improments.  I could not help but wonder how this set was still working with the digital broadcasts?  Was it connected to an adaptor?  BTW, they just don't make electronics (or most things) like they used to.  Can you imagine your PC running for 15 years? :)

Particle trap

CRT TVs are perfect for reducing the particle count: the bigger the screen, the higher the voltage. And the screen faceplate is also very effective.

Wanna clean it ?
1st: vacuum cleaner - 2nd: compressed air - 3rd: vacuum cleaner again.
And don't forget: it's a bad idea to use the compressed air other than outside the house :)

Truly beautiful pictures - looks like the hoar frost that you see on a cold clear winters morning. And it certainly counts as a fix.

around here you have to pay the recycling place to take the TVs. They'll take anything else for free.

I've seen some dust in my time but that would take the cake......

Sad, isn't it?

Our local charity shops won't even accept a CRT TV now unless you give them a set top box with it,,,,

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
