I live in San Diego. It is a city that is really no more than reclaimed desert lands. I live in east county, which is still desert like, as yet not reclaimed by "greenification". The main body of the dust around here id fine silt. Much of that kicked up by the nearby airport as they don't know how to create or maintain a lawn either.
When we move gear around in our factory floor, there is a LOT of "brown dust" on the top surfaces. As these items get moved, the dust adheres to one's hands. Said dust gets moisturized at the micro level by the oils and seat produced by one's hands. Still looks dry, still feels dry, yet guess what COLOR it changes to?
Yes folks... that's right... it turns black. Doh!
Since the anode supply of ANY given monitor exhibits a very high corona and e-field, it attracts said dust, and ANY non-conductive particulates, including oils and smoke products, which, to the dust, is MOIST. Dust adheres. Dust turns black.
End of Line.
The MCP should have de-res'd this Rod twit twenty years ago. He is a bad program.
I just whacked him upside da head wit' a blue disc!
TRON will find your program error, and correct it. You can run, but you can't change the facts, boy.
Flyback Transformers do NOT exhibit dust in any way, shape, or form. Period.
