Hi,
I just bought new Xoom 2 and I have 1 dead pixel. Is it enough to put the tablet on warranty repair?
You have to check with your warranty papers.
From what I know, you need a percentage of pixels to be dead in order to issue a refund/replace.
Something like 7-8% .
Just like monitors & tv sets.
That would be entirely too high of a percentage. Usually it's like 3 or more dead pixels, or 2 connected. Are you sure they are dead though? If they are just stuck (dead pixels are black, stuck pixels stay red, green, etc), then you should be able to just find a flash .GIF file or even an app that flashes all the colors to get it fixed.
This must be a stuck pixel, is only visible when screen is black or very dark. Am I able to repair it just flashing this place with gif image?
edit: now I have 6 stuck pixels, the rest are smaller, I probably didnt see them :[
Return it to where you purchased it or send it in, that's unacceptable. While you're at it...just take back the Xoom 2 and get a Xoom.
Entire Screen is color dotted I cant see anything rebooting the phone wont work taking out the battery wont work. Ive taken best care of this phone and had a case mate, never even dropped it on top of having a case mate, what seems to be the problem? Its very aggravating going to bed with a phone working waking up finding out that your phone wont ever display anything again, I had this problem 1 night before this happened the night before it happened for about 10 mintues so I ignored it got home from school took a nap, and its permanent. any ideas? thank you
Maybe it is dead or stuck pixels
I had an issue which was similar to yours a couple of months ago. Actually my phone fell and some black spots appeared on the screen. First I thought am screwed badly cause they kept on spreading all over the screen. But after I searched internet, I found some information on this topic. There are some softwares on play store which help to find and remove stuck pixels. But, in my case they weren't useful. So I searched more and found a thread on xda where a member with the same phone had the same issue. He kept his phone in the fridge everyday for a few hours and eventually the dead pixels came to life. I followed the same thing and my phone came to life in a matter of days. Thanks to him, now my phone is perfectly fine. If you have stuck pixels, then you can try those play store softwares. Just search dead pixel on play store and check what you need. Stuck pixels are colored dots on the screen and dead pixels are black dots on the screen.

My Atrix2 flew from my hand and fell flat on its face onto the tiled floor, from about 8 feet height. The phone appeared to be fine, but I felt roughly about 2% its pixels became dead. The phone was fine otherwise but the dead pixels were plain irritating. Didn't have time to visit Moto service. Guess what, on their own the pixels are becoming alive, which was predominant today evening. I think, about 1000 of those pixels are still dead. Those of you who are knowledgeable on LCDs please explain this self curing mechanism. Am I lucky? For info, phone runs on stock ICS and screen is ON for about 2 hours a day.
Me too, but I think the cold weather was the reason, lol.

Thanks for sharing. But, I live in Bangalore, India, where it is hot nowadays. There has to be another reason.
The past two weeks I was reading a lot of pdf docs on the mobile. Is it that the prolonged voltages to the pixels brought them back ? Happy anyway.
maybe if anyone has this problem shall try to completely seal the phone and put it in the freezer,,,, then tell us the results.

That's a good one! Removed the battery and kept the phone inside the freezer for about 4 hours. Then dried it under a fan for 5 hours. Switched on in the morning. Voila, hardly about 200 pixels at still dead. Will try to bring all back to life in the evening. Thanks a lot.

Hey, sorry I just saw this.
Are these Pixels dead, or simply stuck. A dead pixel is black, and never on, a stuck pixel is locked to one color. Stuck pixels are common, and actually a certain number per screen are allowed to slip through in manufacturing, but if you have a bright one, it is really annoying. (trust me, I know, mine has a bright green one in the lower right since I got it.)
Stuck pixels can sometimes be cured just by time, and more commonly by flashing multiple colors rapidly in the problem area. There are many apps for this in the play store. They don't always heal, but it is quite common, unless you are me, then they never do.
Dead pixels probably do not heal under normal circumstances, however yours were caused by the shock of being dropped, which could have just disrupted some of the stuff in the screen, and potentially they could self heal.

Thanks for the info. I had lot of black pixels (in clusters) scattered all over the screen. The flashing screen apps could not make any impact. That idea of keeping the phone in freezer really worked. After three brief visits into the freezer, only about 90 black pixels on 6mm, 2mm & 1mm long lines remain. Week end may see the end of these too. I owe this to XDA.
BTW, only today measured the screen size, to know the count. It is a rectangle of 96mm x 54mm; 10 pixels per mm.
And the good thing it heals for ever - I hope so - it's been about 6 months since the screen heal it self, and since I watching it when the device over heat from 4G usage, and still okay, lol

Wanted to report that ALL those dead pixels are alive now, after the phone spent about 10 hours inside the freezer yesterday night.
So, folks, those of you with dead pixels on the LCD screens can try the freezer method proposed by abd-hhh, before visiting the service center, if you don't have time or are out of warranty. I hope the dead pixels don't appear again. Here's hoping for the best :good:
My Motorola Attrix 2 got same problem

Hi. I've tried your way to restore those dead pixel. In first time try, those dead pixel seem cured a little bit, but then it becoming back as before where those dead pixel reappear again. So, i tried one more time, but only 4 hours in fridge (not in cold storage), the dead pixel come to alive, but then still turn to dead... I just wonder, what temp of your fridge when you put your atrix 2? Did you wrap it closely tight? I want to try above then 4 hours, but i just afraid my phone will really 'dead' totally. Can you give your steps how you doing it?

Wrap with some paper then remove the battery and kept the phone inside the freezer for about 9 hours. Dry it with some tissue then switch on the phone. All dead pixel is gone (before is 4 hour in freezer about some dead pixel left after that the dead pixel spread back)
This is awesome, I'd really like to try this on my phone as it sounds like exactly what is happening.
A relatively minor drop, with no physical damage noticeable, has caused some pixels to go black/colors. However, I noticed that move sometimes! Like, one morning I woke up and found the pixels that used to cover a certain notification on my home screen had shifted over so I could see the notification!
I tried applying pressure and noticed that I could sort of make the dead area get bigger, then let go and the edges would sort of return to the earlier size. It almost seems like the LCD has too much pressure being applied and that's what is preventing those pixels from working. That's why I think the freezer trick works- the temperature changes cause the metal and silicon to expand and contract, hopefully returning the screen to its original position from the factory!
Here's my problem though- I don't have a Motorola Atrix. I found this thread doing a search. I have an HTC One X (sprint version, EVO LTE), which means the battery is built in. Should I be concerned that putting the phone w/battery into the freezer is a bad idea? I'm guessing due to condensation?
Perhaps it is worth dismantling the phone to remove the battery? What do you guys think? I tried to find reference of people doing this with other non-removable battery phones (cough* iphone *cough) but couldn't find much on that topic.

It's should work on any device with lcd screen.. But with battery inside...., I can't gift any word on that...
Btw.., If u wrapped any puff-up battery and put into freezer it will back to normal shape and still can be use normally...
