One SUB-PIXEL dead on XDA-TRION- DOA? - 8525, TyTN, MDA Vario II, JasJam General

Hi!
I've just received XDA TRION- from o2 UK. My missus is really happy with this phone (so am I) but there is one small SUB PIXEL dead (always green)- left, upper corner which is quite annoying when watching films and doing other stuff. Should I send it back (under warranty or DOA) or leave it as it is?
O2 UK.
Cheers
Chris

Doubt that they will allow a replacement/refund due to a single stuck pixel. Most companies have a minimum number of defective pixels on TFT display before accepting warranty repairs/replacements.
For example the large computer company I work for specifies that at least eight pixels must be stuck on a 17 inch monitor and these must be in areas that makes the pixels "stick out" (i.e. close to the center).

How often is the "dead pixels" problem?

Hi guys!
I'd like ask all of you how often is this problem in Hero series?
I bought one a month ago and it has some stucked pixels, but I heard that the chance of getting even worse phone is bigger, so I decided to keep this one, because these dots are practically invisible during the common work with the phone.
I can see one or two if I set the brightness level to full, but thats my second question- how many of you use brightness on full or you do prefere to keep it on automatic? I discovered that on manual setting the phone loses light sensor function, am I right?
A couple of dead pixels here too... But can only really see them when I boot, so it's ok. So far...
p.s. I use half of the brightness. Full brightness i s great to show off but sucks up too much battery!!!
A few can been on boot on my phone too. Not really a big deal though.
From all opinions I got (plus from the other forums)- here is the statistics:
38 people don't have any/ 34 do have this issue...
Not good for HTC...
Hardly an exhaustive sample! Plus, you're more likely to get "positives" based on the thread title, because it's far more likely that people with dead pixels will read it!
That being said, it is *very* common, and not just on the Hero. You don't need to google for long to find that the iPhone has similar issues.

Dave
Yes, you are right, but still.. even those people with this problem are enough evidence that it's something wrong with the quality control. I am not saying that it's happened only to HTC Hero, but it's a big problem in general and I don't agree to give 400+ boxes for getting stucked/dead/bright and so on pixels. This is just kind of thinking, and when the manufactures realize that it would be much painless for us- the clients. It's all about the quality control- in general- monitors, TV's, cameras, laptops...esspecially when the items go above define price. You get it what I mean..there is no room for joking with the clients. Ok, I am gonna change the device- once, twice, three times, but where goes the starting point that has made me convince to buy exactly this model? Nowhere..the same with Iphone, Sony Ericsson, Nokia... We are living in 21st century and the perfection is tide connected with this time..or at least that's my point of view...
The issue is that the yield of 100% "perfect" LCD displays is actually quite low. As this article states (under Quality Control) it is economically prohibitive to throw away otherwise perfectly good LCD panels for the sake of a few dead pixels.
Unfortunately, as it currently stands with LCD manufacturing methods, for us all to be *guaranteed* screens free of any dead pixels, we'd probably have to pay an awful lot more for our devices since many screens would end up having to be thrown away.
Regards,
Dave
Ive got none however I do have a little light leak in the top right of the display
I have 2. But I dont think they're dead pixels but dust that's visible on the black background with booting. Cannot see them at all with normal use.
If they were completely dead pixels it might have been more nasty.
It's in the nature of fabricating lcd displays. And has been a problem for a long time. Anyway, with my Hero I can't be bothered about it.
If you have stuck pixels, try JScreenFix. Its free from the Market. worked for me!
i had alot on my first device.. i traded it in.. this one has 2.. they only show up during booting.. so i guess its not a big deal
I've had a couple of Heros by now:
1. very visible dead pixel (centered in market search field) -> returned
2. Really large gap on top side of display glass -> returned
3. happy until after 3 months suddenly loads of dust appeared below display glass -> returned
4. dead pixel in prominent place -> returned
5. I'm very happy again. hope that dust will stay away from underneath the display glass.
So, my personal record so far: 4/5 Heros are flawed (3/5 Heros on arrival).
That's really sad as it is such a great phone otherwise.
I've posted about this before, if they appear as bright white specks when brightness is up full (such as during the boot animation) then it's dust, not dead or stuck pixels. You can open the phone up and remove them. I've seen it on multiple handsets, turned out to be dust every time.

In my case the first pixel was permanently green, while it was a red pixel in the second case, definately not dust. (I think these are correctly called hot pixels, not dead ones.)
i hab a dead pixel on the first day after i bought it. But i went to the T-Mobile shop immediatly and they changed my hero with a new one without any problems! With my "second" Hero i dont have any Problems till now. Seems like there are 2 generations of displays!
*edit*
my dead pixel was near the upper left corner and it was totally white. actually you could only see it if the rest of the screen was red or black. but as it was a mistake i changed my hero anyway!

Will 1 dead pixel be covered by warranty?

had my hd2 since launch and loving it, i have however just noticed a dead pixel on the right hand side of my screen. whats the chances of this being covered by warranty?
HTC in the UK state that 10 dead pixels gets you a new handset. They also told me, when I asked them about my 1 dead pixel, that this is a progressive issue and it would eventually get worse and reach the 10 pixel limit. It might be worth you asking HTC support so if we can see if this is a consistant policy.
Regards.
ํI don't think so. Anyway, you should ask your local HTC support.
And...did it get any worse?
I noticed one dead pixel on mine to...its very tiny and can be seen only on 80% or more light off display.
So, can number of dead pixels rise?
weird, I obtained a DOA from HP when I noticed a couple of misbehaving pixels on my ipaq 214...
Since we're talking about a top-notch device for today's standards, where the display is the main attraction, I simply cannot imagine how a single dead pixel shouldn't be covered...
If LCD TVs/monitors are anything to go by dead pixels aren't uncommon and a single dead pixel is something you just have to live with. As cMMY69 said, you need a cluster to qualify for a replacement.
From my experience, dead pixels don't multiply (not to deny that they don't multiply), I had one on my old 22" LG monitor and it drove me up the wall as it was dead center in the middle of the screen.
Mine is very very tiny and smaal... left-down in the corner of LCD...very hard too see. Only when the backlight is 80% or more i visible...and only if you look very close. Its not a big deal, just wanna know that it can't spread all over LCD 1--3 is ok...more it will get me angry
No more dead pixels for me but I'm always drawn to it as YouTube videos appear to have all been designed to display white images where they show up my dead pixel
No...they will not cover it. I had 1 dead pixel on my MT3G in the lower left corner of the screen. I usually check for these things before I even leave the store but at the time I did not even notice it.
They told me that it had to be "obstructive" before they can swap it out
I had the phone since launch day of the MT3G and as of Wednesday it had never spread. No one else using the phone ever noticed...but it is frustrating when you know its there, my eye was always drawn to it.
...My HD2 screen is perfect, the sales rep was really cool and evened opened the box before he scanned it so I could inspect the screen for flaws

Screen littered with white stuck pixels. HTC policy? Warranty?

My screen is littered with white stuck pixels. Best visible with an all black image and 100% brightness. I don't know if they were there from the start. I guess I was too excited with the HD2 to even notice them at first.
Now I have at least 7 of these stuck pixels and 2 of them are only 2mm apart.
I can't find the policy regarding dead/stuck pixels anywhere. Not on the HTC site (I live in the Netherlands, Europe) nor here on the Leo forums or even trying google.
Does anyone know the dead/stuck pixel policy HTC has in Europe?
I bought the device on december 12th.
It would also be nice to use this thread to find out if more people are having this problem with the HD2.
Thanks!
EDIT: Added a poll. It might be nice to know how many of you are suffering from dead pixels to get an idea of the quality of the HD2 LCD screens used.

From what I've read in another thread, someone spoke to HTC when they had 1 dead pixel and HTC said they'd need 10 before it was a warranty issue. Personally, I think it should be an issue if there's any dead pixels, especially when the thing is only a month old!
Get in touch with them and see what they say themselves.
I'm waiting for an answer from HTC. They are not that fast..
I also read that thread, but to be honest I've never heard of so many pixels needed to be dead to be covered by warranty.
The title of that thread states only 1 dead pixel (which is normally not covered by warranty), so I thought it would be a good idea to open a new one and check out the experience of other xda users.
Found this for the Asia Warranty, and it states on page 4 of this document, http://docs.google.com/viewer?a=v&q...&gl=uk&sig=AHIEtbQJk8yP96b-ddibr9YKV3EYPCjKXg
14. Due to the complexity of liquid crystal displays on handheld devices, dead or bright pixels
may sometimes occur. If the following occurs within 14 days from the date of purchase, then
you can ask to replace the LCD at our authorized service centre.
(a) 3 or more dead/bright pixels (*) anywhere on the liquid crystal display.
(b) If there are only 2 dead/bright pixels, then they must be within 5mm of each other.
(c) However if the conditions listed below occur, then this warranty is null and void.
(*) ”Dead pixel” – a pixel on the liquid crystal display (LCD) that shows no light at even
when it is supposed to.
(*) “Bright pixel” – a pixel on the LCD that shows only 1 color (usually white) and no other
colors at all.
What (C) refers to I don't know.... the 2 conditions below are knackered pixels! Give them a ring - on laptops it was 6 or 7 accross the screen, or 3 or 4 towards the centre. I wouldn't tolerate that many on something like a phone, as you're looking at the entire screen all the time.
Good luck
Again a different answer. I hope HTC replies soon.. Someone on tweakers.net told me they look at a % of dead pixels. I think I will give HTC a ring tomorrow instead of waiting for an e-mail.
Wow. I had four of these, the last one I sold still sealed in its box but the other three were perfect with regard to not having dead pixels. How unlucky! If I were you I'd return it for one of the numerous other faults, never mind their dead pixel policy. Say the SMS fault is the issue, or the crackling call quality (if you have it) etc.
Those faults are something to try indeed if they reject the pixel claim.. However the sms issue can probably be fixed with a hotfix.. Can't say anything yet about crackling call audio, didn't use it to call yet. Still playing with it and awaiting my soft resin case + screenprotector
I just noticed another white pixel.. So that is a total of 8 already.. Seems like they are all suddenly appearing (not that I'm paranoid, but I didn't notice any white stuck pixels before and I would swear there were "only" 3 yesterday morning when I first noticed..)
Ok, I gave HTC Netherlands a ring and here is what they said:
There need to be at least 4 dead/hot/stuck pixels present, OR
There need to be 2 dead/hot/stuck pixels at a maximum distance of 5mm from each other
So I brought my HD2 to back to the store I bought it from and they have sent it in for repair/exchange. I don't know if they will replace the screen or the complete handset, but I pushed them quite a bit to replace the entire handset (it's only a month old and I don't like the idea of it being taken apart already :S) I'll keep you all informed.
Good to know.... hope yours comes back fine!
Are you sure you are not seeing the touch screen matrix?

Thank you! I hope so too! Good thing is that they (the store) also filled "in perfect condition" in on the RMA form. Sent back a Nokia once and it came back all scratched up and I couldn't fall back on anything to prove it wasn't scratched when I sent it in.

Indeed
I have a UK Tmobile HD2 Ive only had it 2 weeks and had noticed a white pixel appear a couple of days ago and now I have spotted 2 more (bottom left, middle and top right of the screen) and I can also just about see 3 not very visible RED stuck pixels.
I will be taking the handset back in to the store tomorrow to see what they plan to do about it, they will probably send it off for repair but i will ask for an exchange although the store does not have any instock.
my HD2 suffers from a dead pixel too.
Luckily it's only 1 (and i hope it won't get any more).
I have my HD2 a week, and yesterday i first noticed the dead pixel with brightness on 100% and a white background.
Hope they do something about your situation, because that many dead/hot/stuck pixels isn't fun anymore, and the worst part is you can't hold your eyes of it once you noticed them.
Is there a software to fix stuck pixels??? I have spotted a red point which can be seen only in some applications with black background. But it isn't seen in a totally black picture.

Any update on this?
i live in NL and curious to hear if its fixed for free.
Black dead pixels?
Are dead pixels black or white? I have few in a small area after I bought it used a year ago. They haven't spread but does anyone else have this problem?
i am on it too .... a blue pixel only on black font.....

Line of discolored pixels suddenly appeared

So yesterday I picked up my phone after it had been sitting on the desk, not even on the charger, and have a persistent line of pixels that are discolored (I don't know if 'stuck' fits with OLED displays). They look like they are brighter than the rest of the screen, however when I turn the brightness all the way up they are still visible. When a black image falls on the line, the pixels don't show there, which makes sense for an OLED screen.
Is there anything I can try to fix this? This is a little disappointing as I've only had the phone for 1.5 months. Didn't get insurance, but since this is what I would consider a manufacturer's defect, and not the result of anything I've done, I should be able to get a replacement I would think.
Probably $35 to get it replaced...insurance is key to all big electronics you get....

Do a dead pixel test (not to see if the pixels are dead) but to see which colors this effects...AMOLED has Blue, Red, Green colors..once you go through every one of those 3 colors you can see which colors its effecting...
if its effecting only a certain color..you can balance it out by making your phone display an inverted image with that color...if its on 2 or more colors, then use white(which is all 3 colors)
You must have had something running that used up the color of the screen on all places other then that line...

Should I keep my Nexus 7 with 1 white pixel?

First of all, this is my 5th Nexus 7. First was bought on the Play Store and RMA'd due to screen lift and flicker. The RMA also had screen lift but no flicker, so I RMA'd it and in the process of waiting for Google to send me the new purchase link, I walked into Office Max and walked out with a brand new Nexus 7 with zero issues. Yeah!!!
Well a week later there was an ad on my local Craigslist wanting to trade a white AT&T GS3 for a Nexus 7 straight up. I couldn't pass up the opportunity and made the trade. The next day I sold the GS3 for $380 and then drove over to Office Max and ordered another Nexus 7(they didn't have any in stock this time). It was delivered on Tuesday and had screen lift badly. I took it back to Office Max yesterday and luckily they had one in stock this time and I swapped it out. The Office Max rep opened the box right in front of me so I could assess whether or not it had the screen lift and it didn't. Problem is, when I get it home and turn it on, I see 1 dead pixel in the very bottom left hand corner of the screen. Just one. No screen lift and no flicker(so far). Office Max offers a 2 year replacement warranty for $49.99 that covers pretty much everything no questions asked which I did pay for.
Since this one is flawless except for that one tiny little pixel, in a place that I don't notice unless I am looking for it, I am thinking about keeping this one and keep an eye out for other issues or more dead pixels. My question to the community here is, would you keep it or return it? More than likely they won't have any in stock and I would have to wait for another to be delivered.
Try using a pixel tester app first, sometimes you can wake them up again.

Tried them all. Problem is it's the very corner bottom left pixel which is covered by the nav bar or status bar no matter what way I have it turned. I've tried hiding the status bar and turning it 180° and still didn't work.

On the subject of dodgy pixels, the Australia/NZ specific warranty contains this little gem...
3. TFT LCD defect policy
Despite the highest possible standards, the intricate manufacturing of thin-film transistor (TFT) liquid crystal display (LCD) screens may still produce slight visual imperfections. These visual imperfections do not impair the performance of Your Product.
However, ASUS will provide the warranty service for Your ASUS Product's TFT LCD screen only if there are at least:
3 bright dots or 5 dark dots or 8 bright and/or dark dots in total; or
2 adjacent bright dots or 2 adjacent dark dots; or
3 bright and/or dark dots within an area 15 mm in diameter.
(Please note: A bright dot is a white or sub-pixel that is always on under BLACK pattern. A dark dot is a black or sub-pixel that is always off under patterns excluding black.)
Not less than 30cm distance, in a straight line, between TFT screen and inspector
Room temperature between 20-40° C
Lighting is between 300 and 500 lux
The above is a get-out clause for Asus if your device has any screen defects less than what is specified. Meaning Asus do not have to replace or fix a device with 2 hot pixels or as much as 4 dead pixels! It's as if they know their product is sh*t so they've included an exemption from being responsible for faulty LCDs. What a joke.

I had already looked into that. If I were to replace it, it would be through Office Max. Like I said, I paid $49.99 for their service protection which does warranty the screen and any defects.
I should have asked, if you had 1 stuck pixel that you barely notice unless you are looking for it and had coverage against it, would you replace it?

The N7 has 1024000 pixels... one pixel is a 0.00009765625% failure rate for that specific device. The idea that they can even reach that level is, when taken in perspective, pretty amazing.
If it were me, the hassle of returning the device and either not having one or having a loaner that doesn't have my apps and isn't set up how I like it far outweighs the hassle of one weird pixel that, as you said, isn't even noticeable unless you look for it. The pixel is a non-issue.
