Re: What's that black dust in monitors?

[Phil Allison]

You only see that jet black crud in a monitor adjacent to the FBT.

** Bullshit - it gets all over the back of the CRT, the ultor lead
and the insides of the case.

The Robot is not even familiar with the issue.

I have seen the "sooty" black dust with that "TV-electrical
odor" in fluorescent fixtures in a restaurant.

I dont get that myself on the flourescent fixture in my kitchen.

All there is on that is some brown fatty crud on the upward facing
surface, and I know that thats the fat in the air from cooking steaks.
I cook them with the griller as hot as I can get it, and you do get
a bit of a grey smoke haze from the burning fat in the air.

Whats on the flourescent fixture is nothing like the
black soot you get on the inside surface of the monitor
case adjacent to the FTB and on the FBT itself.

My hypothesis is oxidized and maybe dark-dirt-coated
particles of grease/vegetable-oil/etc., maybe oxidized.

Yes, thats one description of what I do get on the upper
surface of the flourescent fixture in the kitchen, but thats
nothing like what we're discussing in monitors.

Maybe smoke particles of some kind, which
are sometimes greasy/tarry in nature.

Yep, but thats greasy and nothing like jet black.

And these sootier appearing particles seem to be attracted to
TVs and some fluorescent fixtures, as opposed to other forms
of dust not being so attracted to high voltage electric things.

Dunno, I do get quite a bit of dust on all the front surfaces
of all the monitors and TVs, but its just dust colored, not
the jet black soot you get inside the monitor.

I have known black dust to accumulate on TV screen surfaces
sometimes, and larger quantities of this dust when wiped with a
paper towel often have the "black-dust-from-the-inside-of-a-TV" odor.

Mine isnt anything like jet black. But then its not a black
soil area, the dirt around here is very brown, almost reddish.

the ultor lead and the insides of the case.

Wrong.

 

[Rod Speed]

Not that I want to be caught agreeing with DarkMatter on anything, but
I have both seen and heard of enough black dust on TV/monitor faces.

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.

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.

Even dust with the odor of that accumulating in the flyback
transformer area. My hypothesis is greasy/stick/tarry particles,

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.

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.

maybe with a thin coating of soot or other fine carbon particles.

And conductive particles can have a net
charge as well as nonconductive ones.
Sure.

My suspicion is that some sort of black dust particle,

Cant be around here where the dust aint black.

probably mostly made of some sort of grease or tar,

Cant be that either, it isnt greasy or tarry.

has a tendency to be charged one way or
another and be attracted to TVs, monitors, etc.

Doesnt explain why is noticeably concentrated
on the inside case surface adjacent to the FTB.

 

[DarkMatter]

Dust ends up in PC regardless of moisture and or
tars and is anything like the color of the black stuff in
monitors. So it cant be just dust as some have claimed.

It is dust. It just happens to take on a different color than the
dust accumulations in PCs. Also, there could have been an epoxy
encapsulated device that failed in the unit.

You are irrelevant.

Even you should be able to bullshit your way out of

I'm sorry, but your pathetic "Don't buy that," is about as retarded
as it gets, considering the well documented effects on smoking in TVs
for decades, boy. You are the child.

Never ever said anything even remotely resembling anything like that.

Yes, you did. I said that it affects lifespan, and you said "Don't
buy that." Sorry asswipe, but facts are facts.

PCs dont generally rely on heat passive
heat dissipation much, so the effect of smoke
or just dust isnt what causes them to fail.

Dumbfuk the discussion is about MONITORS!

You are a fuckwit.

You are an adolescent twit, AND a snake oil salesman. You have the
credibility of a freshly laid turd.

Have fun explaining why you dont get that
on the HT lead from the FBT to the tube.

Or with Tesla coils either.

Game, set and match.

Yer a fucking idiot. This baby bullshit proves it. "Game set and
match" How fucking childish and lame can you be?

Hey! Retard boy! Yes, YOU! RODDY DIPSHIT!

Monitors are left on for hours on end. Tesla coils are rarely
turned on for more than a few seconds at a time as they are definite
FCC violations, you diphsit FUK!

Game,set, and match, my ass. You want a match, go look at a big
cowpie, then go look in a mirror.

 

[DarkMatter]

And you dont get that black soot inside an electrical
heater where there is something to burn the dust.

Dipshit. Electrical heaters radiate huge amounts of IR and air
convection currents as well. No dust gets anywhere near them.
ELECTRICAL FIELDS are a completely different story, however, you DUMB
****!

 

[DarkMatter]

Natural/unforced convection will also make sticky particles stick onto
surfaces. Less than with forced air, but it does happen!

Of course.

** No need to explain the Robot's false assertion.

Anode leads also get accumulations. Time scales simple differ
between materials, and corona levels.

By me at least, and by others, I'm certain.

Wrong.

This retard Rod Speed has opened up one monitor case, and now he
thinks he's a fucking E-field expert.

The word was "some"

Obvious lie. The words you clearly used were 'no one'

and who is Harry ???

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 ?

Also, there could have been an epoxy encapsulated device

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.

that failed in the unit.

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.

Completely and utterly irrelevant.

Pathetic, really. No wonder you're completely unemployable.

There is no such common problem.

Pathetic, really. No wonder you're completely unemployable.

Black soot is commonly found all over the HT
cables, backs of CRTs and TOP areas of the case.

Pathetic, really. No wonder you're completely unemployable.

I do see that stuff on a fair number of those leads.

Monitors are left on for hours on end. Tesla coils are rarely
turned on for more than a few seconds at a time as they are definite
FCC violations

I have operated a couple for quite a few hours, and they did not attract
that dust. I suspect DC electric fields pull that stuff out of air more
than AC electric fields do. (And those fluorescent fixtures that had it
may have needed 50,000 hours to get a noticeable amount.)
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.

NOT around the radiating elements though, dipshit. Only in the air

Do try to keep up, boy.
