What's that black dust in monitors?

[DarkMatter]

Dust color discrimination eh ? So its fairys sorting out the
different colored dust and putting the jet black dust into the
monitors and the other non jet black dust into the PCs and
onto the front glass tube surface of the monitors eh ?

What part of the words "take on" are you having trouble gleaning the
meaning of, little boy. Does everyone have to hold your hand through
EVERY post, you retarded fuk?

It is NOT that color when it settles and attaches. IT TAKES ON that
color AFTER is has been there a while, you stupid twit!

 

[DarkMatter]

Yep, like the FBT. Which might just explain why the
jet black soot that you get on the inside surface of
the case is adjacent to the FBT. Funny that.

Not epoxy encapsulated, dipshit. I was referring to a semiconductor
package smoking. Please leave the thread. You are an absolute retard
as it relates to electronics.

 

[DarkMatter]

Doesnt have to have failed. All monitors that have been
used for any length of time have that jet black soot on
the inside surface of the monitor case adjacent to the FBT.

Game, set and match, I believe.

You're an idiot. They give off nothing. They exhibit a field,
however, which DOES attract particulate. What is so hard about that
for your 4 inch thick skull to grasp?

that you get some one the FBT end given that the
black soot ends up on all surfaces around the FBT.

Fair point.

Thats not the reason they arent left on for
anything like the sort of time monitors are.

I have operated a couple for quite a few
hours, and they did not attract that dust.

The ESD air 'purifiers' certainly do. But its not
black soot, just whats obviously visibly just dust.

I suspect DC electric fields pull that stuff
out of air more than AC electric fields do.

Probably, but the ESD air 'purifiers' are DC.

(And those fluorescent fixtures that had it may have
needed 50,000 hours to get a noticeable amount.)

I've never seen the same jet black soot with them.

And the ones in my house are over 30
years in use now, with no cleaning at all.

Neon signs don't seem to attract that black dust with the
"electric dust odor" that increases when I wipe it off.
Maybe being more exposed and the lack of DC allows
a different dust to dominate, so that the dust is not black.

Yeah, no argument that substantial voltages do end
up attracting a lot of dust. Thats very graphic with the
outside front surface of the glass tube with monitors
and TVs. Its just dust colored tho, not jet black soot.

Thats not the jet black soot you get on the inside of the case adjacent
to the FTB with what you do get on the outside glass tube surface.

Sometimes, although more often not, it is black and has the
"inside-of-a-TV" odor when you wipe it.

Presumably you get that in black soil areas where the dust is very dark.

The dust around here is reddish brown and thats what
builds up on the outside front surface of the tube, due to
electrostatic attraction. I still get that jet black soot on
the inside of the case near the FBT, so that cant just be dust.

Dust on my monitor face is darker than other dust in my home. And the
soil in my area, and in the neighborhood several miles northeast of me
where the TV had "inside-of-a-TV-like" dust on the front face, is not that
dark.

The black soot on the inside of the monitor case near the FBT
isnt sticky/tarry/greasy at all, its completely dry to the touch.

I think tarry/greasy particles coated with soot (or something else dry)
or oxidized into something with a drier surface. Maybe similar to cobwebs
- which are dry to the touch initially, but turn out to be gooky if you
roll them up in your hands. And cobwebs are black - certainly darker
than ordinary dust - and it does appear to me that electric fields and
maybe ionic currents play a role in their stringy formation.

So is the dust that gets electrostatically attracted
to the front surface of the tube, just a completely
different color and coarser/more gritty to the feel.

Usually, not always.

Have fun explaining how the dust that settles
on the inside of the monitor case adjacent to
the FBT 'takes on' that jet black color.

AND other dust colored dust inside the monitor case doesnt.

Fraid so.

You have always been, and always

Yup!

Not all dust particles are equally prone to carrying charges. Different
materials rank differently on the "triboelectric scale". Maybe that black
stuff is prone to carrying negative charges, and that would explain its
being attracted to positively charged surfaces, especially any with
corona.

Ever notice that cobwebs are not the same color as ordinary dust?

It never is around here. Presumably the dirt is different colored.

Mine doesnt.

Mine isnt. And I just checked that using a damp paper towel,
and both a monitor screen and a table top thats visibly dusty.

And the soil in my area, and in the neighborhood

"inside-of-a-TV-like" dust on the front face, is not that dark.

Dont buy that either, the jet black soot is too fine.

The jet black soot from the inside of the monitor
case adjacent to the FBT never gets 'gooky'
no matter how much you rub it with your fingers.

And cobwebs are black

Not here they arent. Quite a light brown, actually.

- certainly darker than ordinary dust

Dont get that either, if anything they are lighter.

- and it does appear to me that electric fields and maybe
ionic currents play a role in their stringy formation.

What ? There are no electric fields near any of my cobwebs.

Usually, not always.

Always around here. Never get anything as fine as the jet black soot.

There aint no jet black soot/dust around here
except inside monitor cases adjacent to the FBT.

But I have entirely electrical heating.

and that would explain its being attracted to positively
charged surfaces, especially any with corona.

The inside of a monitor case doesnt have that.

They're lighter colored than the dust here.

The anode lead is DC, but it fluctuates. It is simply dust, AND
moist or oily particulate that has carburized after being there for so
long. TIME is the big factor here. Even after several hours, a tesla
coil wouldn't start to gather dust. It is an entirely different
animal. AC, not electrostatic as in the charged capacitor that a huge
CRT tube IS. Hehehe...

 

[DarkMatter]

Yes, it is most definitely one assured reason. The main reason in
this country.

Do fines and jail time sound desirable to you, dipshit?

 

[DarkMatter]

Probably, but the ESD air 'purifiers' are DC.

No. They are very high frequency rectified AC switcher output,
usually. Quite noisy actually, with ripple figures in hundreds of
volts.

They are not "air purifiers" either, dufus. ESD "fans" for the work
bench are for carrying the flux smoke from soldering operations away
from the operator.

AT NO TIME should forced air be blown across an ESD workstation.
The fans are for PULLING air away from the work area ONLY.

They also DO NOT clean the air. They merely have a medium level
ionizer integrated into them. No cleaning, just ions, and air.

Get your shit straight, you guess as you go twit.

Your brain is full of jet black soot. You ARE the one!

Bwuhahahahahahahahahah...

This is one of the most retarded remarks that you make, and you make
it often. Says a lot about you.

Have fun being a simple dolt retard about it.

You're an idiot... A retard even.

You should really stop trying to project your insignificance onto
others. You fail miserably.

 

[DarkMatter]

The inside of a monitor case doesnt have that.

You're an idiot. Whenever a corona field is present it affects all
the surfaces around it. Were your precious monitor encased in a
metallic faraday cage, I would agree. Being that it is in a
non-conductive plastic shell, I would have to say that ANY fields
inside the case affect the inside surface of the case, since it is
non-conductive.

PRETTY FUCKIN' BASIC, BOY!

All over this lead I have seen this stuff quite a few times - although
not always. Back in the late 1970's and early 1980's when I was not yet
working, TV sets on the curb for trash pickup were a source of many parts
that I needed, so I have enough experience.

Fair point.


Thats not the reason they arent left on for
anything like the sort of time monitors are.

Sometimes is, and for whatever reasons it is still relevant that most
Tesla coils don't see the runtime that monitors do. But other relevant
items are the fact that a few Tesla coils see lots of operating hours
and also the lack of DC component in the electric fields that they
produce.

The ESD air 'purifiers' certainly do. But its not
black soot, just whats obviously visibly just dust.


Probably, but the ESD air 'purifiers' are DC.

Do those have a fan to bring in dust besides what the electric field
would attract? Don't they have the electric field more confined than TV
sets have and lower voltages than TV sets have so that the black sooty
dust is less attracted until it gets sucked inside along with other
dust that dominates due to being sucked in by a fan?

(I have heard of a few older negative ion generators that cause black
dust to fly onto walls!)

I've never seen the same jet black soot with them.

It is not usual; I am just saying it does sometimes happen. Maybe
specific to a restaurant where steak sandwiches are made or where things
get fried in deep fat friers with partially hydrogenated soybean oil,
maybe cigarette smoke has something to do with it.
It does not seem to happen with most, nearly all fluorescent fixtures
elsewhere. And it stopped happening when the fixtures in the restaurant
in question were retrofitted with high frequency electronic ballasts and
T8 lamps as opposed to the older T12 lamps. But when the fixtures in
that restaurant had magnetic ballasts and T12 lamps, the fixtures did pick
up a little of that black dust that, when wiped with a paper towel, has
that "electric-black-dust-inside-a-TV" odor.
Another bit of data: The T12->t8 retrofit in that restaurant involved
reducing the number of lamps per 2-foot-by-4-foot fixture from 4 lamps to
2 lamps. Tolerance of burnt out lamps was greatly reduced - before the
retrofit, usually at any time a couple fixtures had a failed lamp. After
the retrofit they kept up something like 100% of the lamps in uptime
98-99% of the time. And I surely envision fluorescent lamps that have
experienced "end-of-life" having a DC electric field, since usually only
one end has a failed electrode.

Possibly weak-but-not-zero airflow through the fluorescent fixtures was
also a factor. In the space above the false ceiling there are air
conditioning ducts and the supply and return ducts are almost certainly
unequally leaky.

And the ones in my house are over 30
years in use now, with no cleaning at all.

Yes, I do concede that fluorescent fixtures usually dont attract the
"electric black dust". But I have found some that did among the many that
I have tracked as a lighting nut.

If it was ordinary dust that carbonizes from corona, then I should have
found the dust accumulated somewhere on neon signs and connections thereto
to be of the "electric black dust" form. And I don't see how fluorescent
fixtures (in the unusual but known case that they accumulate some
"electric black dust") would carbonize ordinary dust.
But no, 10-year-old dust everywhere on neon signs seems more ordinary.
Looks more likely that the "electric black dust" is something different
and is different even as soon as it's precipitated from the air. It seems
to be a clue that cobwebs are also rather black in color.

no matter how much you rub it with your fingers.

25 years ago I got many of my parts from TV sets tossed onto the curb,
so I ahve handled lots of that "electric black dust". I have found it to
usually be a little greasy if you squeeze it and dig into it, although it
is perfectly dry if you touch it lightly.
