can stuck pixels just appear suddenly? - HD2 General

literally out of nowhere, I noticed a small white dot after 4 months of daily use. Could a microscopic drop of water cause this and can it be reversed?

could simply be a pixel that has died......

it does not show in dark background and blooms in a white one. what do you think? is it pixel or something else?

i read somewhere a while ago of someone who had successfully unstuck pixels using a colour cycling program. I'll try hunt down the link to the thread later, (though i dont hold much hope, i never commented in the thread)

Dead/Bright pixels problem?

Hi guys.
I'm interested to know whether Hero sets from overseas are experiencing this problem. apparently, users who bought it in Singapore (where i live) have this problem, and it's pretty widespread.
just curious to see if the problem is limited to Singapore or it affects other territories as well
Hi. I have T-mobile G2 in UK and I also have dead Pixels. As Fact I know people have this problem and It's not rare. I didn't send it back cos I Can live with it but i know people who sent it few times and still have received with dead pixels. Sad but its true.
i got 1 tiny little bright one.
annoying at first but i forgot about it after a couple of days. theres more important things in life to worry about. besides, most bright pixels right themselves after a few days/months...
i'd live with one or two dead pixels myself, but people have reported up to 8 dead/bright pixels, so it's kinda worrying
I do have around 8-10 dead? pixels but you can't notice them. One of them is bright enough to notice on black backgrounds and menus, but you hardly notice the other ones.
It's kind of weird though, they all appeared after 1-2 days of usage.
I have 1 bright pixel after 2 weeks using. The shop don't change the device with one dead pixel. Sad. In Hungary/Europe.
2 bright spots here. they are really tiny tho and i only ever notice it while booting which is not that often. no dead/stuck pixels on my hero *yay*
stuck = bright
sounds like someone needs to create an app for Android, like the apps to fix bright pixels on normal computer monitors, where u select the region on the monitor where the bright pixel is and the app constanly flashes different colors...sometimes rectifies bright pixels after a couple of hours.
i believe some of the bright pixels might well be enclosed dust ...

i have to say that i don't have ONE dead pixel on my screen. It's really great. My past device (xda orbit 2) also had another problem: dust gathering beneath the display. i don't have any issues with the build quality with my htc hero and i'm really picky too.
it's an unbranded german white HTC Hero.

If it was dust though, wouldn't we notice an increasing number of bright pixels as the days pass?

i haven't looked into this myself ... just quoting other people here.
the people in the other thread seem to have come to the conclusion it is dust enclosed in the assembly process. the seal around the displey seems to be quite good ... so no new specks of dust over time

Me too, I have 8 - 10 dead pixels but it hardly to notice them! you will notice them when boot the device.

i am not sure if mine is considered dead pixels but when the device boots up, the upper right side seems to be brighter than the rest of the screen (light shining out more from there)
however, once the device is booted up, it is no longer noticeable, maybe becoz the screen is not totally black. the only way thus far i can replicate this is to shutdown and boot it up.
does anyone have this issue?
Yeah, I also got the brighter screen in the upper part of it during boot, I think it is because of the backlight to the device so I don't think it's you really need to worry about.
But concerning the topic, I also experience dead/bright pixels during the boot up, around 3-4. I didn't even notice them during boot before I saw this thread and decided to take a closer look, not that a huge problem for me as i can only see them during the boot, and neither got I the patience to wait for it when it is at service.
first day with my hero from orange france and 1 dead black pixell !! RRRRRR

Stuck Pixel Desire HD

Hello, i'm sorry for create duplicate thread from http://forum.xda-developers.com/showthread.php?t=1093995 because i did't get any answer, so i decided to open new thread at this subforum, because many ppl look at it
few weeks ago [3 may 2011] i bought a new desire HD
and today, i realized there's a stuck pixel at the top right panel near the clock, the panel gray and the stuck pixel just colour almost same, take time and focus to realize it.
i create a new thread because all other threads of the stuck pixel didn't give me any solution
and this stuck pixel not just stuck in 1 colour
but,
when the screen is white, the pixel is red
when screen blue, its blue [dissapear]
when screen light purple, its light purple
when screen black, its black
when screen green, its blue
idk if the pixel really gone when its blue or purple, but my eyes are normal i guess..
JscreenFix tested, 1 hour, no work
tapping, scrubing, massage method, no work
is there any other method that you recommend?
i didn't root the phone yet because it still in Warranty, and i guess if i bring it to HTC Care, i won't get a new unit, but a new lcd, and the mechanic sure open the phone and broke the void sticker..
any suggestion?
If you have tried all the above I would phone HTC and try and get it replaced...
Good luck as some people have problems replacing phones with dead/stuck pixels as they are allowed a certain percentage of dead/stuck before its deemed a fault

The HTC didn't want to replace it, but i contact the shop where i buy and ask them for replacement, but still is there any other method that someone had test it and work?
I'm not suggesting this, do it at your own risk, don't blame me if you brake anything!!!
There is a way of "unstucking" the pixel by pressing hard on your screen(so I've heard, never had a dead pixel in my life=>never tried it). It looks like that your pixel isn't actually "dead"(it would only shine in one color(white) or wouldn't shine(black) if it was), but rather "stuck"(again, so I've heard, and didn't do any research about it, how and why is this happening, so there's a big chance I'm wrong).
If they won't replace your phone, and you don't really want to try exotic stuff that might break your phone(like pressing hard on the screen/dissassembling the phone and poking the screen from behind with the screwdriver/yelling loud at it), there isn't really anything that you can do about it, except get used to it...
I've had a stuck pixel on my Desire HD since 4 days after i purchased it, which was at the beginning of December. At the time, i tried everything i could to fix it but nothing worked. So now i just learned to live with it.
Btw, i really recommend to not try push/massage on the screen because the glass on the DHD does not flex. If you apply enough pressure you could shatter the glass (considering it's not gorilla glass).
So if JScreenFix doesnt do anything then im afraid nothing can really be done, unless you decide to disassemble the phone yourself (i dont recommend), or brake your phone purposely so HTC will replace it

It takes 3 dead pixels to replace it with a new one, here were I live. I have one on my DHD, but it's in the down right corner, can't even see it, noticed it by accident when i was watching a video that was cropped so it had alot of black around it.
Otherwise, don't see it-don't care
I've even had a dead pixel on my Philips monitor, for 1 year, and then it just dissapeared. And it was a red ugly one, right in the middle of the screen, very annoying.
I've had a stuck pixel for some time now. It's bright red and in the middle of the screen, i just lived it. I barely notice it. Only when i look for it do i find it. I'm tempted to say 2.3 fixed the problem for me but it could just be that i changed my wallpaper from the live sense one to a black one.

Strange pixel problem...

Hello all. I have a weird problem about some pixels on A501 screen: when the screen is on and the background is black, some of them will show "bright"... but not white, i'd say some sort of pale gold or very light brown, but again not white. With other backgrounds (red, blue, green, white) those pixels acts as normal, not being distinguishable from the others.
Is there something I could do? The issue is a lot more noticeable with 100% screen brightness.
Update: I sent the tab to service repair, and they sent me a new one. Guess what? Same problem again, right where it was on the old tablet!!
Definetely they are not stuck or dead pixel (I can say that because of the color of the pixel)
I was thinking, since I use a Tucano Youngster Case (http://www.tucano.com/shop/youngster-for-10-tablet-pc-1.html) which has a magnetic clip on the back, could this be the issue?? I'm going to try to take a photo at this pixel and attach it here.

that would be a better way to ask.. give picture so that we can see your problem..
hmm.. i would deny the fact that magnet will affect your screen.. thats why i hate those casing with magnetic clip on it.

Unfortunately pics won't show my pixels, they're just too small. However I tried passing another magnet (more powerful than the one on the case) both on the screen, with a direct contact, and on the back, where the case's magnet is located, but no other pixels got damaged. So I don't think the magnet is responsible... Does the iPad folder case has a magnet in direct contact with the screen too? If that's the case I believe that magnets don't affect screens at all (imagine iPad's owners complaints?).
What do you think?

Well, when I set my background as black, on this one and two other Android tablet I had, it sometimes show a short brown/gold line on the top left of the screen. Most of the time its not there thoough. So it just seems to be a software thing. Although I do not have any problem where pixels appears randomly throughout.

Can you get a pic, so I can try to say if we're talking about the same issue? However, my pixels are always there, even in the "Acer" and "Android" boot screen... so I doubt it's a software issue.
Just a heads up... Yesterday I got my 3rd Iconia, and guess what, same problem again. I think I will just live with it... but I'm extremely annoyed.
Does anyone knows what kind of problem can this be, with gold-coloured pixel only with black background?
You should load up the Screen Test app that sets all pixels to red, blue, green, black, white, etc. in sequence as well as displaying several resolution and gradient screens and see how those pixels react.
I bought one A500 that had bad Wi-Fi but all pixels were perfect. Exchanged it last weekend for a second one with working Wi-Fi and all the pixels are also perfect. I don't see any gold pixels.
I'll disagree with your statement "Definetely they are not stuck" in your second post because if they are always gold in all screens they are indeed stuck. Not stuck on white or black but still stuck on that one color.
Does this happen on all home screens or just one? I hope you can post a picture of some sort because I don't know where to look to see if mine has the same issue but, running Screen Test, I don't see any incorrect pixels in Screen Test.

I ran a pixel test app and with ree, green and blue pixels everything is perfectly fine. Only with black background I can see them. I tried to take photos but pixels are too small to be noticeable :-(

Can you tell us exactly where to look? In Landscape mode, how far from the left/right top/bottom edges should I look and how many pixels am I looking for? How many should I see that are not completely black?

Among three tabs they were in different numbers and position... however they were between 3 and 6, and in the middle (vertically speaking); horizontally, instead, i found them twice on the right half on the screen (volume keys up) but this last iconia I have right now they are on the left. I also managed to get some photo, I'll post them later.
EDIT: Unfortunately I forgot my camera's MMC at home... will get back there in 10 hours and post the photos. However I ran Pixel Fixer during the night (an app which alternates red/blue/green/white screens very fast) but the pixels were still there this morning.

I ran through all the colors in Screen Test and found only ONE bad pixel across the entire screen and it's only when the pixel is supposed to be blue; it's black instead. That same pixel is correct on all the other colors though.
Otherwise, at full brightness and on any color, they are all on correctly and off when the screen is set to black. I don't see any other colors as you describe.
If your screen is doing something similar across three different tablets, maybe it's something you are doing but I'm not sure what it could be.

Please note that this issue is present in the Acer and Android boot screen... what could I do wrong in that phase?
Ok, here's the photo. The three pixels are inside the white circle.
I just rebooted after setting display brightness to full and did not see what you see. I guess I'm no help. Sorry.

Dead pixel?

I just got my warranty replacement yesterday. Noticed last night in a dark room that there is a small stuck blue pixel in the virtual soft button area, really an eye-sore. My first device had a hole in the backlight that looks like a big spec of dirt, so not as bad as that, but still irritating. I always seem to have the worst luck with ordering electronics (went through 5 sensations going around the warranty system )
Does anybody know of a way that it might be possible to fix this pixel? It's only visible when there is any blue or white on the screen above it. So if I download that pixel fix app and set the background color to blue, that stuck pixel screams, but if I set it to black or gray, it's not visible at all. It's only on if something above it is on. Almost like it's a short in the signal or something. Anybody know of a way to fix it? I've tried the pixel-fix it apps to no avail, albeit I haven't tried for more than 5 minutes.

Pixel fixer apps don't really work, some may report success only because it is an intermittent pixel fault that will just come back or would have fixed itself anyway. If it was as easy as flicking through a serious of colours the manufacturers of LCD panels would do this already as it costs them loads of money in throwing away panels with faulty pixels.
Some pixels will fix with gentle pressure, but often will just come back.
I'm sorry to say the only option is an exchange.

I'm getting a red pixel that shows up randomly. Either by the notification bar or navigation bar. It goes away if I touch the screen. Is this something that could get worse?

You have a faulty pixel that corrects itself sometimes when given a little bit of flexing as would happen when you touch the screen. It is unlikely to spread to other pixels, but one day the pixel may become stuck red permanently or may just fix itself for good.
It isn't uncommon to have pixels like that, although with improvements in manufacturing it's getting rarer. If you think it will annoy you, you have little option but get it exchanged.

Phil

Didn't realise you were a mod
Its a strangely behaving pixel too. It only shows if there are a lot of blue sub pixels activated on the screen. Example, if the entire screen is blue, the stuck pixel will scream, but if its red, green, or black on then rest of the screen (dark video or picture or something) the pixel is black. Unlike any stuck pixel I've had before. Only stuck blue if the rest of the screen has blue... And if the pixel is supposed to be showing black. If it's showing white or gray, it'll function properly, but if it's supposed to be black, it'll be blue.

Dead Pixel or another thing?

Hi Guys! (I post this question in the Android central to)
After 5 days with my LG G6 occasionally I download the Antutu for an benchmark, but in the program I see the option to test the screen for find Dead pixel, and Boom! I Find it. :crying:
After a lot of tests and try to see more closely I can't say if it's a Dead Pixel for sure.
So I'll put a link here with images of the screen, hope you can help me.
postimg.org/gallery/24s8sglq4/
From above the area that are afeted is black, but from the sides is white or in the color of that the screen is showing in the moment.
Ps .: I already talked with the place that I buy it and they will replace, but if I can find another solution will be bether.
Based on your first 2 pictures it's a hot pixel, based on the last one it's a dead pixel. It needs to be RMA-d most likely.
One thing you can try (low chance success) is to run this Youtube video on max brightness and full screen for a day. https://www.youtube.com/watch?v=VN-KIlsxxOw
reply
Thanks in advance Gabbbbbb
So, I try aome apps to recovery read pixel but neither work.
I have another guess now. Maybe can be a dust behind the glass, because looking closely in the black one we can see the colors of the screen.
I have just today to change for a new phone, after they will send to the warranty and I'll be a long time without phone.
I don't know if a keep or not
