display dead? - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Hi. I have noticed a small dots (a lot of them) on my screen especially prononuced when the background is black...has anyone seen this yet? I am still on 4.4....

Looks like a chunk of dead pixels.
Did they just suddenly turn up? If you didn't mess with your tablet, this should be covered by the warranty.

Hi. No i am extra careful with my tablet and despite being an year old it is like new...and not rooted everything is stock...i didnt noticed it until a few weeks back but it is difficult to notice it because it has to be black background...but they dont look like dead pixels as they emit a different color in games...very odd...it seems i will have to contact a repair center or i might wait for lollipop to see if it will magically fix it but i doubt it

It's quite common. Send it back to Sony. There's a thread about it in the help section that I posted in

Had the same issue here. It took 4 days including shipping.

On the bright side, you might end up getting a new tablet

Looks like you have a galaxy forming inside your tablet. Keep an eye on it, if you see the specs disappear from the center of the cluster, it means you have a black hole growing in it, and you need to take the tablet to Mt. Doom ASAP.

Random Spots Developing on TITANS / 6800's

I have the XV6800 and noticed that this phone over times developes some screen spots. I have one so far, and on my previous one that I returned (for other reasons) developed one also.
I read a thread on another website that Moguls / Titans develop it too.
Has any one else Developed this? If so is it fixable or is it something that might cause like sometype of recall and issue a fix where we might get phone replacements later on?
i have a light spot about the size a pea in the screens lower left-hand quadrant. It's noticeable it during the verizon boot-up screen with the white background, in word, etc. anything with a white background. Not noticeable if the screen is colored.
I've wondered if this was normal.
mine's got 3 of them now
same here, my burnin spot is also in the lower left-hand corner the size of a pea.
same here, lower left corner is lighter than the rest of the screen...looks like somebody missed something on QA

Yes, mine is in the exact same place. I read on another website that it might be an HTC issue because other TITAN's have gotten these spots also.
At first I thought that a picture image was burnt into my screen or that I might have pressed the screen to heavily and damaged it.
This has happened twice. I wonder if there is a fix because this is very annoying especialy when trying to read or watching a video.
Same Here
I have a pc6800 through Alltel and just noticed the same problem three days ago...has anyone spoken with their SP and found out if they are replacing them?

I am afraid to take mine in since my all High and mighty Moister sticker now says void even though my phone hasn't been with in 100 feet of water. I find those stickers to be such BS...but that could just be me...I wish I could find some where to buy spare ones..

I am not entirely certain but I think the void sticker that is displayed by the battery is for the screw. I mean if you try to unscrew your phone to fiddle with the insides then that voids your warranty. I could be wrong.
The only concern would be that if we where to return the phone to get a replacement one, that we would have to flash our RADIOS and ROMS to stock if any one has flashed them to anything that is not stock.
The stickers on both of my alltel 6800's said void out of the box. Their explaination for this is the when the sticker get wet the words bleed and turn the entire sticker purple. Not sure how accurate the rep was but that is the story for what it is worth.

Yep..you are right . The void stickers are good until they turn a solid purple or red...weeehhh...I'm goin to go and replace my phone this week will let you know how it goes..and what they say
Yeah, mine's got a spot the size of a small pea in the bottom left-hand corner. Doesn't bother me too much yet though, I've got the insurance so I'll go get it replaced one of these days. For others that have tried to get them replaced, any troubles?
After doing some research on forums I noticed that many people have this problem.
Some say that it might be an issue with the phone heating up, faulty LCD manufacturing, the excess use of the vibration feature and so on......
But It seems that no matter what you ( such as gettting a replacement) your current or new phone might still get these spots.
It seems that not many carriers know about this issue, not even HTC.
So the problem might consist unless it is made known to them so they can create a fix for the new shipment of phones. Or else this will reoccur on the phones they have shipped out already.
It sucks because most of us paid a large amount of money for these devices to have it be faulty( not something that can be fixed via software at this moment). Just my opinion.
Ditto, same spot here. was wondering about the spot for a while. I have dropped mine a million times and thought it was because of that.
would be nice to be able to change it in because of the spot because mine is beat down to the ground like 4 flat tires.
will they give me crap because of how beat up it is?
I know every time I go to Alltel and get a phone replaced via the insurance the first question they ask the Rep at the store is if the phone looks like it has been dropped or if it has water damage....I'm sure that is so they can blame it on the user. As far as the phone being under manufacturer warranty they usually just swap it out for me no questions asked. I just always hate when they open the box infront of me and give nothing but the phone....would be nice to have an extra case and charger...LOL..
anyone know if sprint good about swapping phones and if i should do insurance or manufacturer warranty and if i do insurace can i switch to touch or you can only change phone in first thirty days
i got 2 spots in lower left corner
Me too (x3)
I've been through three Sprint-branded titans because of this. I'm 100% sure it's a design flaw. If we all complain at once, HTC might actually listen and make a titan that doesn't do this!
I also have two pea-sized spots in the lower left quadrant of the screen. Doesn't really bother me though, as I only notice it when the phone is booting up.
I've got 3 spots lower-lefthand corner as well on my Mogul.
I made a poll to actually see the statistics of the effects of these Spots on the TITAN / 6800

Got my transformer, two small bright spots on the screen

Two small pinpoints of white light on the screen. Are these dead pixels? Stuck Pixels?
I'm guessing that either way I should exchange it. So, apparently Asus is going to be having quality issues?

let it load
select "fix my screen"
if it doesnt go away after it runs... if it doesnt auto close after a minute, just close it
its a dead pixel
return son!
No dice. Thanks anyway.
Guess this bad boy is going back...
I got a replacement Prime yesterday and thought everything was perfect until I opened my web browser to google, which is pretty much all white and noticed a bright spot like you are describing in the title. Mine are definitely NOT stuck/dead pixels. I know because I returned my first one in part because of stuck pixels. It's almost like these pixel(s) allow slightly more light through than the adjacent pixels. Sort of like light bleed but not at the edge of the screen. I can only see it on white or very, very light backgrounds. It disappears entirely on darker colors.
It is unfortunate but I will not replace this again for a third time. It goes away unless my Prime is charging or docked (which I assume is because it is similar to the tablet being plugged in) and can only be seen on an all white background. I will never use my tablet plugged in, I charge it at night when I sleep, and the limited amount I have it docked is not an issue since it only shows up on an all white background and seems less noticeable than a dead/stuck pixel. Honestly, a smudged screen is more noticeable/annoying. Since I don't use my dock much it will probably end up having a dead battery anyway which means I really wouldn't see it much, unless the battery in the dock is required for it to function while attached, I'm not sure but will find out. Thinking about it I guess it probably does need to be charged for the ports and everything to work unless it leaches off the tablet. Who knows...I'll test it at some point.
It is kind of strange though and I really dislike trying to justify a flaw to keep a $500 device but whatever. IPS screens have some nice benefits but they seem to have a lot of flaws too like bright spots, pretty bad light bleed and more stuck pixels than I am used too. I went back and forth in my OCD head so many times about how many times I would exchange or return this device before I get one that is pristine but if I return it there is nothing else that interests me.
Asus had quality issues with their past Transformer and to think the 1080p tablet will be any different is ignorant.
Anyway, end blog. Since that's what XDA is now

If it's only 2 pixels and they are not directly adjacent, it's unlikely that they will take it back as that is deemed an acceptable tolerance for dead/stuck pixels. I think you need to have 5 or more total or 2 directly adjacent.
Pretty much all manufacturers use this guideline I believe. I hope I am wrong and you do get to exchange it.

I had one dead pixel on my Xoom and Best Buy replaced it without even turning it on to verify
I had two stuck pixels when I first got my Prime. Running pixel fixer apps didn't fix the problem. However, both of them have "unstuck" themselves after a few days of use. If you have some time before you have to return it, you may want to wait a little.
EDIT: Check that. I just ran a dead pixel test and only one of the two unstuck itself. The other one is so unnoticeable to me that I haven't seen it.

Same issue here, bottom right of the screen, small patch of white light in the browser window about an inch from the corner..
Not sure whether to return, the rest of the tablet is awesome!!
I just got another one and about 7 dead pixels the kind you can see on
Black screens and also slightly a bit of light bleed where the headphone jack is

LCD "Mura" Defect (aka, clouding, hot spot, white spot)

My Prime has developed a small bright spot in the center of the screen. It's only visible on white or light pages. I didn't drop the tablet or anything, it just appeared. Anyone else experience this?
EDIT: Here's a link showing a laptop with similar looking spots. The one on my Prime is much smaller than any of these, but it's a similar looking mark. I tried getting a picture of mine, but had trouble doing so.

EDIT2: I've learned that the defect I'm talking about is called "mura," or "clouding."

I have 4 of those spots.. three are within one inch and one of them is at least 3 pixels. I also have poor wifi, so I want to kill two birds with one stone. as soon Asus has a fix for the wifi I will rma..
I have the exact same "brighter" spot at lower center of the screen, don't remember it being there when I first got it... it's very annoying, I think I will send it back for repair.
My friend's first prime had that on his screen (2 white dots) when he bought it only visible on a white screen. He returned it for a new one. Thats why its important to check for those too when you first get your prime and put it through inspection, Just open up the notepad like app, that one has a white screen.
got one too. need to send it back for repair, just been too lazy to do it...
Read somewhere that those are stuck pixels. There's an app in the market that's suppose to fix stuck pixels as well.

I'm 100% certain the spot wasn't there when I first got the tablet, as I did a very close inspection of it. Actually, I was reading through a thread in an iPad forum and there were reports of spots like this showing up on some iPads after a while.

Thanks, but this is different than a stuck pixel, which I also have (I found the stuck pixel when I first got the tablet, but it's so unnoticeable 99% of the time that it doesn't bother me). The link below shows similar looking bright spots on a laptop (the spot I have is much smaller than any of these, but it's the same type of spot).
http://pics.livejournal.com/laptop_mechanic/pic/000p062e
same story here. my prime has 5 bright spots (hot pixel) as well. i did not notice them when i got prime last year. pixel fixer can't fix these either. i can live with these spots though.
Sent from my Transformer Prime TF201 using Tapatalk
I have the same problem, 1 bright pixel just below the home screen indicator.
It doesnt bother me that much, its the only problem i have with my prime and knowing theres lots of people with more problems im not gonna return it for a new one, having the chance to get one worse than i had...
My phone had the same thing when I first received it (still does), but it was my understanding it was a "hot spot" created by adhesive or undue pressure in manufacturing. It's not stuck/dead pixels, in my case at least, and my Prime has no such spots.
I however don't know what would cause something like this over time. Seems to me something in the screen is poorly manufactured and overheating...
Sent mine back and was told by Asus that the white spot is a kind of light bleed that caused by pressure at the area, they will replace the panel for me.
I've noticed that mine has a few white spots similar to who you guys are describing. Mine has two about an inch apart from each other near the lower left-middle of the screen, and another near the right hand side of the screen. I don't notice it when other colours are present, but on a white/light surface, it can get very annoying. I'm thinking I might call ASUS and see if I can get it RMA'd since it has other problems as well. The WiFI is actually pretty ok, but GPS is a total bust. I don't really care about the GPS that much, but it might be what I need to send this in. I'm just worried the white spots will get worse with time.
After reading up on this a little more, the name for the white spots we're talking about is "mura" (google "LCD mura" and you'll get some hits). It looks like it's somewhat common on cheaper displays.
Also have this appearing on mine and also didn't have it before.
I have only noticed it in the last week since I installed the latest update.
I only really notice it on the XDA site.
In my case it's definitely not mura (clouding), but more like pressure spots or pinpoints (usually 2-3 pixels in size.) They are more distinctive in shape than clouding. Either way, sucks for any of us to get these kind of issues. I've actually got an RMA # for mine and will be sending it out either tonight or tomorrow whenever I get a chance.
this can be mura, spots, poinpoints or w/e
i can tell you another one..... so i was working very hard on many several things on my tfp.... sending emails, writing proposals, getting images, working on ideas ect.
I started to get annoyed on how fast the tfp goes to sleep, so i decided to put it to Never. So it never went to sleep and it was awesome because my concentration kept going and i was jumping from my laptop to my tfp back to my laptop ect.
THEN.... i decided to go to sleep and i left my tfp opened connected while it was charging. I completely FORGOT that i had disabled tfp from sleeping. So it sat on the Home screen of my launcher.
When i woke up several hours later, i started to use my tfp and i noticed there was a white area that on every screen it was still there.
It was the outline of the icons! This is the reason why screensavers we're created so this wouldnt happen. This is an excerpt from our trusty wikipedia: (btw, apparently this isnt suppose to happen in lcd's but i assure you it happened to me on my tfp, its not that bad though, as i barely see it sometimes)
Before the advent of LCD screens, most computer screens were based on cathode ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods of time, the properties of the exposed areas of phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen. Cathode ray televisions, oscilloscopes and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent.
Screen-saver programs were designed to help avoid these effects by automatically changing the images on the screen during periods of user inactivity.

So, let me ask you this OP, did you by any chance leave your tfp on for a long time with something on the screen? and the glow that you have now resembles that image/icon/object you had on the tfp?
If that happened to anyone, hit the thanks

Nope. I can say with 100% confidence that I didn't leave anything displayed on the screen that could have caused this. The spot is very small, and is just a little random blotch that doesn't resemble any type of image/icon/object. I've tried taking a picture of it with the camera on my smartphone, but I get those vertical bars that you get when taking a picture of a computer monitor and it's hard to make anything out in the picture as a result. Would using a regular camera allow me to get a good picture? If so, I'll see if I can borrow one and post a pic.
Also, the spot wasn't there when I first got my Prime, and it appeared after about a month.
As of now, I've decided against RMAing it, as (1) I'm afraid of getting back another unit with one of the other myriad of TFP problems, and (2) I don't feel like being without my Prime for 4-6 weeks.

Add 1 to the of people with the pinpoint brightness issue, mine showed up after about a month of use.
I am also waiting to RMA or exchange at BestBuy once he seem to have all of the issues worked out since I have one of the relatively good ones now and don't want a broken one.
dead or stuck pixel
i have almost a half inch bar worth of dead or stuck pixels with more grey tint cloudy looking smugges..on the top portion of my screen..i can only see this when the screen has grey or anything in the grey family. i have not dropped, got it wet, or anythin to it..its been working great for me until about 4 days ago. how and what do i do about getting a rma. i have emailed asus but stilll not heard back..its realy starting to piss me off..this is going to be my 3 one..the other two i was still in my return time at best buy and game stop..this one i am not..any help will be great..would post pics but when i take the pics its hard to see or tell what i am talking about..

[Q]What should I do?

Okay, so the other day I somehow managed to drop a dumbell on my phone. So I got the entire screen replaced which cost $250 (screen didn't display at all).
Anyway, everything works fine...except for one thing. Some colours tend to give off a faint red "glow" to them. So for example, when pulling down the drop menu (CM10) the border around the notificifation icon (so around the picture of a cloud) is slightly red, and whe apps behind it (transparency) look a bit red as well. Plus, when it comes to black colors, it doesn't look as clear.
Hopefully that all makes sense. So pretty much, I told the guy that and he kept telling me that it's the software. So I completely reset it, the latest CM10 on it and still has the red tinge. Has the same thing no matter what ROM I put on it. Could it be that the graphics settings are all weird, or is it the job that he did on the screen.
What do you think?
Sorry if this isn't the right place, I just don't know what to do as I forked a bit of money to get this.
Might be a non genuine/non Samsung screen ?
Try gb or ics and if its still the same,go back to repairer for a fist to face discussion.
And you can get a screen here fitted for £80(so if your quote is u.s dollars youve been ripped off).
What do you want us to do? It sounds like a physical problem. You know the problem and you know how to fix it. Take it back to the guy who replaced the screen and talk to him. There is nothing anyone on XDA can do for you.

Damaged pixels in screen

When I look at my screen there's a couple of spots that are really bright it looks like the pixels may be damaged. It almost looks like you can see to the back side of the screen. I've had an otterbox defender on it since I got it, plus its never been dropped. I just got the phone a week ago. If I take it back to get replaced will I get a new phone or a "like New“ phone?
I really hate to see this on a new phone. Any suggestions.

If you bring/send it back to verizon, they should give you a new phone. If it is through insurance, you may get a refurb but the phone is still new so they may only have new ones in stock.
best bet is call verizon and see what they will do.
I've got a similar spot on my phone but it doesn't bother me enough to ship it out for a possibly refurbished one. It's a single spot in the upper left portion of the screen that I can only notice when the screen is completely dark. I'm guessing it's a relatively widespread issue since I think I've heard something similar at least twice before.
