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?

I think from his description we're all sure that he's 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.....

One Vibrant brighter than the other

i have two vibrants that i just bought recently, one of them is mine one of them is my gfs, ive used mine for about a month now, hers we just started using today and we put both phones side by side and on hers the screen doesnt seem as bright, and like menus have like some brown color to them or just not as dark, on mine they are black like solid black, mine received an update idk if thats it?
any help is appreciated

You can try to exchange her phone as I don't think it has anything to do with a software update most likely it's hardware. I bought an iPhone for myself and then after 2 days bought another iPhone for my wife and mine was far less bright and also had a yellowish tinge on the screen while hers was very bright and had a cool blue tinge. Best thing would be for your gf to exchange her phone while she can.

identical settings? (no auto adjust)
screen protector?
different roms?

i have also noticed this. In my situation, i called in and replaced my old vibrant because i complained about a lag so they sent me a new one which was cover under warranty! when i received the new one I quickly put in my spare batteries in it and turned it on. First thing i noticed was the color of the screens. my old vibrant had more of a tan/brown hue when compared to the new one. The new one had more of a blueish hue to the screen. i tried fixing the brightness but that didn't fix it. so i had to decided to go with the old brown one or new blue one. of course i chose the new blue one but i was concerned that i would have an off color screen. a couple of weeks after shipping the old one back i discovered that when you open the video player and start playing any video..press the menu button, then press settings, then color tone! dont know if this setting carries onto the rest of the phone...hope this helps!

[Q] HD2 WHITE BLOTCH/SPOT on DISPLAY...does anyone here NOT have one??

I bought a second-hand HD2 off eBay which to all intents and purposes is in excellent condition, however it has lighter blotch where the backlight is brighter than the rest of the display. This is very clear on white backgrounds and I find it quite annoying.
Tomorrow I am getting the HD2 picked up for a (hopefully) warranty repair; I was hoping for some feedback from the good people on here as to their experience with the phone as I have FIVE friends with HD2s, ALL of whom have a lighter blotch on their display, some worse than others.
This makes me think that it CAN'T be an incredibly rare phenomenon for this device.
I have owned a number of capacitive screened devices and have never seen this on any other handset. Even battered up old iPhone 2gs don't seem to have this problem.
I'm a bit concerned about the screen developing a spot again; I'm also concerned that HTC will try to charge me for the repair....
Anyone got any stories to tell about their screens developing blotchy patches and how HTC responded? And has anyone owned a HD2 since launch that STILL has a perfect screen?
Just be interested to know

Mine has 3 spots showing when on a white back ground but I choose to ignore them. Also sometime my whole screen goes white like a negative photo but I just reboot and the screen goes back to how it should.

I have them since i dropped it and the top corner of my screen got damaged. my gf does not have them at all!

No problems with screen here...purchased dec '09

I contacted HTC (I purchased my phone off ebay) been told it's still under warranty they are collecting tomorrow and said it would be 10 days until I get my repair back

I don't have this problem, but i always keep it in the leather condom when not using it. I did have the negative looking screen once but that never happened again. I think as long as you are gentle with it after it's repaired then it shouldn't happen again.

A picture of the screen would really help...

Had that problem with my first HD2(bought it the first day it was available at expansys). I sent it on warranty and they have replaced few things(including mainboard, lcd and touchscreen).
I have a new one as well and this problem is not present.

Screen with dark smudges

Hi, I know there are a few thread discussing about the screen where black line or so call dead pixel can be seen.
I bought the first batch Galaxy Note in Malaysia (it comes with a free Samsung case). I can clearly see dark smudges on the display especially with gray and green background. I brought it to the service centre and made some comparison with another unit (the technician's) and it displays the same dark smudges by at different intensity. This unit is the first batch Galaxy Note too.
Anyway I got the screen replaced and the new screen has no such dark smudges. The question here is, do all first batch units have this problem?

LoL, today is 14th day since I gave my Note to service center due to incorrect gamma and black clipping. Still no information, no response for my yesterday e-mail. I must admit that I noticed such problem too but it was so slight compared to bad gamma that I did not considered it as a real problem. How long did your repair took? According to Polish law if I don't get any information today I will have a right to full refund. ****ing fags, I hate that country. Always that same. Never better.
Probably not all first batch units have that problem. However there are so many variables. I know a bit of Manufacturing systems. Technological Engeneers probably have setup tech process wrongly. If the QRQC worked correctly they fixed that problem and there will be no further Notes with screen problems. It's always a matter of time to setup process the most flawlessly.

For what i know. Some screens have those dark smudges more visible then others, mine had noticeable smudges in gray and white backgrounds only with lowest set brightness. Nothing too annoying for me... There are some example photos on the forum that i found not acceptable though...
On the other hand, this weekend found an entire line of dead pixels in my note's screen!! Oh well. Just sent it for repair and might take 3 weeks...

Here in Malaysia, it normally takes 3 days to for the service. However, I think due to the recent Chinese New Year, it took 1 week for them to get their hand on the replacement screen. They let me have my Note while waiting for the part to arrive. It took less than 1 hour to replace the screen.
Btw, just to express it again, the new screen is dark smudges free.

I had my screen replaced on the spot too. Screen had smudges and they replaced it within the hour. Thumbs up to Samsung Malaysia.

Screen replacement

Hi,
Dropping my phone was the worst thing that could happen with my phone.
I found someone who would do the screen replacement and after nearly two months he finally returned the phone two me.
At first glance it seemed ok but closer inspection have shown me that:
- the panel used was JDI instead of LGD so a japanese panel instead of the 'original' LG
- serious screen bleed contouring the whole screen
- highlights on the screen, points in the screen where I can clearly see the backlight being brighter than everywhere else
- luminosity is lower than the original.
The last two points are very annoying. I compared my phone with a phone displayed in a shop and I see that the screen on the shop's phone is brighter that mine, even without adaptive brightness and @ 100% luminosity.
Could this be due to different panel manufacturer (JDI instead of LGD)?
The screen bleed could be due to the screen being badly glued but I am not sure...
But the bright speckels are annoying also. In bright areas this is very much noticable, a white picture shows two small areas brighter which indicates to me that the back of the panel has something behind that 'pushes', hard to explain.
Anybody had similar issues or had his screen repaired?
You can see my issues in the attached screenshots...

I don't think your issues is the panel type, i replaced mine and got a JDI from eBay. I don't notice any difference from my old one, which was not JDI. I would say you just got a poor screen. Not the fault of the installer either, i would try to get hold of the screen seller, or just accept the loss and replace it again.

I can agree that the panel type is not the culprit but the screen bleed is definitely the installers fault.
I am not very happy replacing it again as the total cost would mean that I could have bought a new phone for the same price...
My feeling is that the seller of the screen has delivered a used screen and damaged the silver back of the panel by removing it from the old device (the bright highlights could be from a prying tool used while recuperating the screen.). Too bad , lesson learned = do not drop the phone as the screen shatters very easily and when repairing, find a reliable repairsman...
Accept the loss seems to be the only option in this case...
Maybe I will have to disassemble/assemble the phone myself and do with with extra love and care and sense of detail....

Since the digitizer comes glued to the glass I'm more inclined to blame the screen/seller than the installer. But you know the saying... "If you want it done right...". All the best on getting it sorted and working properly.
