Dead pixel - Acer Iconia A500

Just noticed on my A500 it has a dead pixel on the left side about half way up and about 1/2" from the edge. Not too noticable but can definitely see it when screen is black there. Gonna return it before my 15 days are up at Walmart and more than likely get another one. I really like this tablet BTW.

Are you sure it's dead or stuck? Stuck pixels can be a white or black but dead pixels are generally ONLY black.
If it's stuck you may want to try one of the many utilities found in the market to get it unstuck before you head back to Walmart. Chances are (if you're anything like me) you'd have gotten it replaced sooner than later though, lol..
Either way, enjoy your A500

I had two units with dead pixels. One blue pixel (subpixel) and one lit. Cheap crappy LCD panels ((

This one is a blue pixel or subpixel I guess. You can't see it at all on red green or white but can on blue or black. I have tried the pixel fixers and let it run for an hour but no go. I want to take it back anyway on day 14 or 15 so I can get another one for 15 days and that should be enough time for peeps to try the Archos g9 101 out. Although this Iconic runs at 1.5ghz all day long so I don't know if the Archos would be any better in that department. We will see.

Week old nexus one, already dead pixels.

Well I received my nexus one about a week ago and I absolutely love everything about it...
Unfortunately I've just noticed two dead pixels on the screen. One top left and the other bottom right. Both about an inch in from the screens edge.
I've seen a lot of posts of people complaining about clicking edges and dust under their screens but I'm pretty sure this is not dust. The specks look identical to each other and are tiny in size. They are mainly visible on light/white backgrounds.
Unfortunately I live far away from any of the Google supported countries so doing any kind of exchange is going to be really difficult :-(
Anyone seen similar issues? Any suggestions?
There's a coupla apps on the market to check for dead pixels.
All they do is flash up white, black, red, green, blue so you can see what pixel is stuck. It might be worth trying one of those just to make sure they are actually dead pixels.
If they were working before, they might just be stuck pixels, and alot of toggling between colours may unstick them.

But if it was a stuck pixel then you would see it lighting up on dark backgrounds but these are only noticeable on white or bright backgrounds.
BTW I have already tried the market apparently and no joy.
Has no one else been noticing these?
I had one stuck pixel that appeared a couple days after i got my phone
but i fixed it and it came back like 5 times.
But knock on wood its been 4 weeks and it hasn't come back.
Mine was weird it would only show on the lock screen and it was very random but once i swiped to unlocked it went away so it wasn't that bad.
If i were you I would return it especially were its two pixels and software isnt fixing it.

OLED have very deep blacks so its hard to tell if its stuck on black or if it is dead
...anyhow if you cant fix it you should return it.
Man returning it is a such a mission as it was bought in Singapore and I'm not even there any more...
I suppose I could find a way to send it back there and then from there back to the US.... heh. The problem is that I only received the handset about a week ago so if these kinds of problems have been reported since the launch whaat says the replacement wont have the exact same issue? Which would then be a massive waste of time and money ;(
Thats the problem i even set up an RMA to return mine but had a gut feeling i would regret it. So i canceled my RMA and prayed the pixel would eventually not stick anymore.
I didn't want to take a chance of getting a referb phone with other issues.
I feel your pain EVERY device that I get now days that has a LCD screen ALWAYS has at least one dead pixel. But to my surprise my Nexus One is 100% fine .

Ugghh.. i think i have a stuck pixel!!

Its right at the bottom of the screen on top of the P in Phone on the HTC dock. Now i've heard that for a pixel to be stuck, it should be only one colour. But the weird thing with mine is that it appears to be a different colour depending on the angle i look at it from. It changes from green to red, and i think blue too. Is this stuck or dead, and anyone have tips to sort this?
Im kind of annoyed because my phone is only 4 days old. And i don't want to send it back because shipping could be costly and take weeks to months.
I have fixed stuck pixels in the past by pressing quite hard on the screen and "massaging" the spot. Be careful not to press to hard, but it can take quit a bit of pressure. There are several causes for stuck pixels, and this wont always work, but from what you have described, this probably will.
You may have to apply pressure slightly offset from the pixel.
Good luck!
I dont know how hard to press, im scared i could do some damage to it. The screen feels like glass so i dont think im reaching the pixel..
DO it when the screen os on, preferably with a white background. Press untill you see the colours go funny.
Its pretty sturdy dont worry too much about breaking it. I havnt actually done it with a DHD, but i have with an iPhone and a G1.
i wouldnt press on the glass lol, your risking breaking it then warranty wont be covered you might just have to either live with it, or send it back to handtec asap.
seems like you got a bad unit stuck pixel and sim gap cover, still surprising since mine is from same handtec batch as yours and its 100% perfect

No matter how hard i press, the colours dont go funny. I know what you mean by this, i have a stuck pixel on my laptop too and applying even a little pressure and the colours change because the screen isnt protected by glass, but by plastic. But doing this in the DHD is another story.
Do you have a Desire HD JamesBarnes? Could you try it yourself? Pressing on the glass until it flexes seems far too risky imo.

I think i'll live with it Im in no mood to send it back and have to wait even more.. i guess im cursed because all my gadgets get stuck pixels. My old psp, my laptop, and now my DHD.
I just tried it, and had the same result, no joy. I guess that means its well built though
See if you can find a stobe application, sometimes rapidly changing the colour can fix a stuck pixel too...
There are certain screen fixes you can run in the browser which flash the colours very fast which can unstick some pixels. I've used it before on a laptop. Just google for stuck pixel fix. Not sure if they will work with the refresh rate of a phone screen but its worth a try.

I downloaded an app called JScreenFix and let that run for 25 minutes. It changes the colours of all pixels rapidly. But still no luck.
They might not replace it if its only 1 singel pixel.
If it's anything like LCD's then they usually have a specific number of stuck/blown pixels before they accept it as faulty..
Usually around 5 - 8 pixels mark...

Correct, but it's up to the manufacturer. For example, if I remember correctly, HP requires 3+ pixels to replace.
for phones its usually a zero dead and / or stuck pixels. you will have to send htc an email asking about their dead stuck pixel policy

Problems with my new iconia tab

Just picked up my Iconia today at staples.... after playing with it a few hours I have found some issues.
1. One stuck green pixel
2. Two bright white pixels
3. Screen randomly turns on
4. Tablet says it's charging when it's not plugged in
EDIT: Staples replaced my Tablet... no dead or stuck pixels this time but I am having some minor light bleeding on the right side of the lcd.
Ill make this simple for you. Take it back for a new one. You can't fix dead pixels and as far as I know I haven't heard of anyone else having any out of the box.

You're certainly not alone with the random screen-on thing. It's a known issue and Acer is working to fix it. As for the dead pixels... return it and get a new one!

Well I haven't seen any threads about bright or stuck pixels so I figured it was a fluke. Going to try to trade it in for a new one tommorow.

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.

Check your new Note 10.1 for light bleed...

I bought a new Note 10.1 at Bestbuy yesterday. Got it home and was enjoying it until I watched a movie in letterbox in a dark room and noticed a "white glow" coming from the bottom left hand corner and shining across about 1/5th of the screen. Never would have noticed it in a normally lit room but in the dark was quite annoying.
Anyway, check yours and make sure it doesn't have this problem. I returned mine and got another one that did not have the glow.
Great :/
Any dead pixels? Just got mine also today, but have yet to open it... crossing my fingers, lol
Ugh, just opened mine and checked it... I also have light bleed in bottom left corner, but even worse at center top of screen as well. Also found a small curved line of dead pixels, shaped like a letter C that is very noticeable on a white background. This sucks, taking it back for an exchange.
I will say this, definitely a very fast snappy tablet, but the low screen resolution is unfortunately noticeable. :/
How can i check for lightbleeds btw? dead pixels i know how to, but lightbleeds, no idea.

Just watch a letterbox movie and look at the corners. There will be some slight glow present but it should be even on all corners and not look like someone opened a door from a lighted room to a dark one.

Exchanged for another, a bit of a pain, they had 3 employees trying to find the dead pixels...
The new one has almost no light bleed, very slight in the bottom left corner, not a big deal though. However I did find one dead grey pixel... weird though, it only shows up on certain shades of green and dark gray. Can't see it at all on a white background and I guess that's what's important, so I'll probably just keep it.

Yes the problem with employees looking for defects is that they are looking at it in a bright room. Also, if it is BestBuy there is an excellent chance they are also idiots.
They make some apps for LCD screens that try to fix dead pixels. You may want to see if they make one for Android.
I'm gonna do another exchange on Tuesday, the dead pixel is driving me nuts, lol.

At BB now, just exchanged for 3rd and opened it before I left. Lo and behold I see a dead pixel in center of screen, lol. They're bringing out #4 now... :/
Update: #4 also had 2 dead pixels, unreal! They're bringing out #5, last one in store, lol
For those wanting to check their screens you can use ES Taskmanager from one of the android stores. It has ascreen checker that fills the screen with solid colors to help find dead pixels and to check color purity. You can use the black color in a dark room to test for back lighting bleed.
I like this guy's:

Btw, Gnote #5 was a winner, no dead pixels! Amazing I had to go through 5 of them, new record for me. They hate me at that BB now, lol.

Thanks for the tip. No dead pixels - checked twice. I'll check for bleed tonight.
Note to everyone. Any tablet will have some small light bleed when looking at a totally black screen; however, it should be consistent between each corner and edge and very slight. If there is a noticeable glow that extends 1 or more inches you may have a problem.
Lol, yeah i know BestBuy HATES people returning stuff and they must have been pissed you blew through 5 of their new tablets. Man that is some serious quality control issues from Samsung. These guys are getting sloppy.
Well the 2 tf700s i returned had lightbleed real bad. This one has it at the top. So bummed out. Will have to return this one now.
