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.

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.

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!

Ghost Images on my screen?

So I'm having a problem and I wanted to see what others are experiencing and what I need to do to fix it or have my phone repaired..
The problem. Anytime I am on a white screen, on the lower half of my display I can see a faint green/yellowish bar that runs across the entire screen about 1/2" in width. Second I can see faint numbers in black.. they appear to be in qwerty order but have a decent amount of spacing. Im not sure if its burn in or what, but keep my screen timeout at 30 seconds, so I have no clue how i could have gotten burn in. That being said. I have full insurance + Tep. I just want to make sure this is something to take it in for before I do.

AMOLED screens are well known to get "burn-in". Its not unheard of at all. Check wikipedia or just search google for more info.

This. Had the same issue (but worse) on my Nexus One. It annoyed me, but not enough to go through the hassle of swapping it out. I'm also beginning to see some on my Epic 4G

same problem here. see my thread about it from a few months ago.

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.

[Q] Have i broken my screen

So basically igot my tablet today and i think i already broke my screen.what i did was i pushed my screen into my dock too hard and now i have this kind of leakage in my screen. Everytime i apply pressure on the leakage it moves around and goes to its original position. Do i need to send it to asus to get it fixed or will the leakage just disappear in time
Ok i just realised the on screen keyboard has burnt into the screen, similar to how you get burnt in images on a plasma tv. Im guessing thats not supposed to happen. Cant believe i brokemy tablet in under 24 hours

I would defintiely return that unit.
Surely attempting to dock it to it's directly supported peripheral is not abnormal usage!

Cheer up bro, just send it back and learn from your mistakes. It was probably defected anyways, get another one and continue to enjoy android honeycomb on your transformer
Sent from my DROIDX using XDA App

Ok i requested a replacement from the website i bought it from. This is my first time returning an item to an internet store. Hope it goes well. Still cant believe it broke, took me ages to find an available tablet

Don't get too mad.
Good luck with the exchange.
Regards.

This is a very rare defect possible on any IPS display. A number of iMacs I've seen have exhibited this, as have a few iPads. I'd never heard of it happening on the Transformer, but it makes sense since it uses an IPS display.
The "bleed" may have been from the screen breaking in some way, or the backlight breaking when the tablet had extreme pressure applied.
The "burn-in" is a defective IPS panel, and wasn't your fault. LCD technology is far from perfect.

wow that's very informative thanks
I didnt realise lcd screens get burn in, i only thought plasma screans had that problem. I guess you learn something new everyday lol

LG V20 pixels burning into screen.. ?

So.. Just today ive been noticing the remnants of a game or video name being "left" "burnt" (if you will) into the right top to mid side down the ride side of my display.. Any ideas? Has anyone else experianced this? Trying to recreate it but its only doing it very fantly currently.. And barley noticable.. But after i had played my game for a little while earlier i could clearly make out parts of the game remnants on my display..

I get this too but it only shows up on grayish colors and it goes away after about an hour or so. Happens mainly with 2nd screen but it'll do it every now and then on the main one. Brightness seems to affect it's appearance more as well. It shows up more frequently for me when Brightness is @ 90 and up.

same here , i am getting the pixel burn as well. what can i do any suggestion?

I'm getting the same problem, called T-Mobile they're sending me a replacement unit to replace the replacement for the original that was bootlooping.

For all with the problem, I suggest getting LG to repair it since it should be covered under warranty. Also, just thought I'd add that LCD screens don't burn in, like their AMOLED counterparts. I believe you can describe this as ghosting, or just say the pixel is stuck on the same color if a customer service rep asks. I could be wrong, but this is what I've heard for most of my life. Hope that you guys solve your issues and return to a problem free experience!

Guys try a program called Pure Noise 2 and let it work overnight. I never had this issue with my Note 4 but even then I periodically ran the noise program. Let me know if it works!

Residual Image
I have this issue as well. From Google sleuthing I've discovered it is referred to as "Residual Image" and it is not a "burn in". It was said that the lcd tech used by LG has this "characteristic". It does self correct. And, most definitely appears most often with gray backgrounds. After seeing both of my parents s7 Edges AMOLED screen burn in issues, I feel we have the better tech comparatively. yay?

Screen Retention\Ghosting
Same problem.
Is covered under warranty?
Did anyone solved this?

This is pretty much the conclusion I've come to after researching for awhile
