Dust between backlight and screen

After talking to a friend who had similar issues it turns out that what I thought were dead pixels are in fact tiny patches of dust/debris between the backlight and the screen. How they suddenly appeared (particularly a new one recently in the centre of the screen) is a mystery, but I definitely believe the diagnosis to be correct - the little dots are grey not black, and they are not square and well defined in the way dead pixels are.
I know that replacing a screen/backlight in a PowerBook is exceptionally difficult, but as in this case nothing would actually need to be removed or replaced, would it be possible to separate the two to clean away this dust?

Hi guys,
That sounds about right. If they look similar to dead pixels but more grey and ill-defined then it seems likely you've got the same problem.
My final solution was... to give up sell the PowerBook to my dad. Bought a new MacBook instead. Shame, because I was hoping to get a bit more use out of it before I upgraded, but there you go.

ThinkPad S440 dust between touch and screen

About a month ago I've purchased an S440, while the machine works great lately I've been noticing dust specs under the touchscreen, and it's getting worse.
Since I need the computer to work I can't afford to send it to warranty and be without it.
So my question is the only way to clean the dust is to replace the screen or is there any non warranty voiding way to do it?
Btw: is there any service center in Portugal? I haven't found any only a support number.

Is there a way to save keyboard backlight and screen brightness settings?

It seems like my settings for the keyboard backlight and screen brightness reset to some sort of default after I don't use my macair for an extended period of time. Is there a way to change these settings so it always stays at what it was last left on?

Are you making the changes through System Preferences? If not, try that and they should hold.

Trash or Dust, between led and display glass

Hi, theres come kind of dust or trash (not secure) between the led screen and the display glass, i did almost everything to remove it, but i cant do it. What should I do?
In advance, Thanks.

If the dust or trash is between the led and the glass the only thing you can do is take it to apple.

Foam sheet between keyboard and screen, Replacement?

Hi,
I'm wondering if anybody knows if this has a part number ? and where can
I get one ?
I'm wanting to know if I can get a factory replacement of the thin foam sheet
that is part of the packing materials that goes between the keyboard and screen.
You know, when your Powerbook was new, when you opened the lid
for the first time, there was that thin foam sheet over the keyboard, speakers,
trackpad the whole surface area. I guess it's more like the foam is the size of
the whole screen area, to protect the screen.
This may seem silly to want to replace this, but I have a PowerBook that's coming
up on 3 years old and every time I have closed the lid (screen) I have put the thin
foam in to protect the screen. So, the screen is perfect after 3 years.
Much different than my co-workers PowerBooks. They didn't see any
need for this foam and didn't use it and their screens are etched / scratched from
the keys, mirror images of the keys scratched into their screens.

Hi there,
I'm not sure if Apple assigns part numbers for their packing materials, but you could either visit your local Apple store to see if they happen to have any of these lying around, or you could purchase a screen protector to do the job.
I used the foam sheet for a few years, but lost it recently, so I went out and bought an iKlear Cleaning kit which included a polish cloth which is the size of the keyboard and trackpad area, and I find it does a fine job of protecting the screen.
Go to klearscreen.com and have a look.

701: dust between display and glass

Hi there,
I have a beautiful Nokia 701 that I bought in March. I noticed that dust is getting into it, between the touchscreen glass and the display... it's really annoying to have a clearblack display or whatever it's called and see dust in between...
Could Nokia just put some sealant at the glass edge to prevent dust to come across? I had to dismantle my old 5800 and there was actually a thin ring made of some silicon rubber (or it was glue) at the edge, between touchscreen and display... and it stayed dust-free for three years... why can't a 0,01 cent rubber ring be added to a 701 shocks me!
Back to dust in my 701... Is there a way I can get rid of it?
Thanks!

I lost faith and decided to keep it as is. Also I'm considering dumping my 701's warranty and trying to do something on my own. Despite Nokia Care is run by kind and competent guys, I just can't get the reason why a NEW phone must undergo their intervention that often.
I'm sorry but I have to acknowledge POOR CONSTRUCITVE QUALITY, terrible organization in releasing firmware variants (701 has, only for 112.010.1404 sw version, 285 variants... a nightmare to roll-out).
I'll look for some how-to guide over the internet to learn to dismantle my 701 without damaging it, and then I will stick some sealant at the edge of my phone's display. Otherwise, I'll just keep it as is with all the dust until I find some other phone. Wouldn't be surprised if it's not another Nokia :-(

White spec between glass and screen...

There is a white spec under the glass on my iPad. It's very annoying. Before I go to the Apple store, I'd like to know what it is that they can do for me.
It's easy to see when the screen is locked and not showing anything.

As you said, there is foreign material between the glass and the LCD screen. Apple may replace your iPad with another one if you bring it to the Genius bar. However, they may say that the iPad is acceptable with that minor defect.

Dust between LCD and glass

Well, my 3rd ipod touch was a week 38. It was great until I noticed there were a few specks of dust underneath the glass, one of which seemed to create a bubble at certain angles. I went back to the 5th ave nyc store today and they were very cool about taking it back. The genius actually said "Yeah, there's no way you could've gotten dust in there".
I've been finding that the 5th Ave store is so much better in terms of customer service than the SoHo store, so I will be doing business with them from now on.
So just in case anyone has wondered about this, the Apple store should give your an easy exchange for dust lodged underneath the glass.
And for the record, the dust-lodged ipod was a week 38 with corinne bailey rae on the cover. My replacement is also a week 38 but with Macy Grey on the cover. I'll see how it works out when I get home. I hope the 4th time is a charm!

It's usually only visible from up close, or under very bright lighting conditions. My replacement had just one speck of dust under the glass, and I figure I'm done with constantly exchanging my ipods.
If you really want to ruin things for yourself, take a flashlight up to the screen and look for any dust specks that you can't wipe away. You'll notice that they might be lodged underneath the glass. I discovered the dust when I was trying to clear all of the dust off before applying an invisible shield and discovered that a few specks couldn't be wiped away.
But I really would say, if you don't notice it now, don't look for it. You'll just make yourself evermore pickier. I wish I'd never done so myself.

How to remove the dust between Lcd and Front glass (Early2009)

I just bought the new Imac less than 1 month
then I found the dust over there
---Should I go to the apple store????

You can quite easily remove the glass front, it's only held on with magnets.
Use either a sucker, like that of a car sat nav or mobile phone holder, or if you dont have that, just get a bit of parcel tape and stick it firmly in the bottom lower corner and gently pull and the glass comes straight out no problems, peel the tape off, doesnt leave a residue then when you've done cleaning offer the glass back upto the frame and the magnets will grab it back into place.

Dust between LCD screen?!

I noticed it yesterday night, at first I thought it was a dead pixel on my T400, but then I realized the color did not change when I did a test... That and when I put my laptop back in my bag and went back home I noticed the 'dead pixel' moved to the other corner, so then I turned on a brighter light and noticed that it's dust between my LCD screen.
It's annoying, and I'm feeling pretty OCD right about now, what can I do to 'remove' it, or would it be better to find a partner technician to remove it? Yes, my laptop is still under warranty.
Solved!

Hi and welcome to the forum!
If you have warranty, then yes, the best option for you would be to contact lenovo service and have it replaced by certified technician.
Hope it helps.

I have Dust inside of the screen of my macbook pro, it has accumulated now and is a big hindrance. Is there any way to clean it

Its a Mac book Pro (Late 2012). Dust is in the display, and its annoying how its in the center of the screen

Hi. the glass in front of the display on the 2012 macbook pro is held on by magnets. If can be removed, but it's tricky.At the store they use a suction cup. The Imac is the same way and I have remove the glass on them. I did it by inserting a thin but sturdy piece of plastic starting at the upper corner and working around the top edge. You have to be very careful or you can crack it. It would be safer to take it in to apple store. I know if too much dust get on the screen between the glass and the lcd it will kind of burn into it.

Stuff between lcd and plastic screen

So I have remnants of ....dust, pocket lint...whatever, but it is in between the pastic screen and the lcd screen. aparently there's some space for dirt to gather there. Is there any way to clean that area out? Does Apple cover this? Big bummer if dust can get in the viewing area.

you may want to alert apple about this, seeing that this really shouldn't happen. try talking to the Apple Support by phone, they should help you from there.

Dust Between the Glass and LCD Surface.

I have a pocket of dust between the glass and LCD surface. I don't even notice that it is there until the screen behind the patch gets darker. Then my ADD kicks in and I focus on it intently.
Can it be cleaned by anyone and not cost me $$$$$ or void any warantees?

I recently had the same problem. I made an appointment with the Genius Bar at the Apple store. The Genius was able to replace my screen with a new one; It took about 10 minutes.
