Nokia C7 Display Defect

Hi,
I have a Nokia C7-00 that was purchased SIM free and unbranded in Germany, with which I'm experiencing distinct colour banding / gradient problems. It is also common on Nokia N8 displays. I'll try to describe my problem:
The first tell tale sign of the issue seems to be a common one: A purplish tint on the top half of the screen saver clock (visible when the phone is keylocked and then the menu key is pressed).
As time has passed by since first noticing this problem- I have also noticed that videos and images that are predominantly dark are also having issues being displayed properly. The effect being similar to if the image was being shown on a screen with limited colours, for example, if you set your computer screen to display only 16bit colours. In areas of images that black is supposed to fade into lighter colours, the image is completely off.
There is an active discussion about this problem on another forum:
http://www.nokiausers.net/forum/nokia-n8/39462-i-think-nokia-using-two-different-types-screen-n8-may...
I have attached pictures of my screen with the problem.
I have contacted Nokia care and they have no input other than re-installing my firmware (which is impossible to do anyway- as they seem to have provided me with inaccurate instructions- there is no way to re-install my firmware via Ovi Suite or the handset)
Any help?
I've since moved away from Germany and from what I understand my 2 year warranty is only valid in Europe...
Attachment 1 is supposed to be black to white squares in increasing gradient
Attachment 2 is supposed to be black into white, but on my display somehow a brown/purple tint is in between the black and white
Attachment 3 is the screensaver clock that is supposed to be black, but on my screen the top half is displayed with a purple hue
Here is an image of two Nokia N8's from someone experiencing the same display characteristics as my C7, and one with a good display. The problem can be seen better in these images:

hi guys my n8 has this issue too
iam not impressed by it and have contacted nokia on facebook , twitter , email and phone yet they dont seem the least bit intrested at the minute
i have even got a nokia tech from a nsc to report it to them via correct channels yet nokia dont seem to care about this
it happends when colours fade into each other or get lighter , main colours are white/grey/black and these turn to a purple/red colour just like in the pictures above
ive also had another n8 and it didnt have this problem , my girlfriend has a n8 too and is on the same product code etc and the screens are so different it is unreal
i thin nokia might be using two screens on the n8 too meet demand as amoled screens are in demand at the minute so maybe they have sourced another froma differnt amoled maker
i cant see any other reason for the difference in image quality between my girlfriends and my screen , same product code , same firmware , same theme and settings yet the results are so different its worrying
forget using the n8 to watch videos if you have one of these screens with a purple tint as the blacks/whites/greys will look purple and ruin the film etc
my video playing has gone from watching dvd quality to watch a dodgy pirate with pixelation and purple tints and banding
id like to see more users post up here so nokia can see there is a bit of a problem and start looking into it as at the minute they dont seem fussed
perhaps people havent noticed the purple tint but if you have seen one with a proper screen and then one with a puple tint you can easily spot the difference the screen quality is no where near as good as the ones without tints , coliurs are deeper richer and nicer to view on the screen wihout the tint
iam waiting for another n8 to turn up today as a replacement if it has the purple screen too i will be extremley gutted and a unhappy n8 user even though its my dream device itll feel tainted because of the screen

Nokia 6233 - Display Cracked on Charging

I purchased a Nokia mobile model 6233 on sep 7th 2007. at Univercell shop at Velacherry, Chennai, Tamil Nadu. Within one week of its purchase, the hands free did not work. When I approached the velacherry Univercell showroom, they asked me to go to Univercell Showroom at Alwarpet. On Sep 20th night 12 pm I plugged the mobile for charging it in the same plug point where I have been charging all mobiles for years. But I was shocked to see the display broken the next day morning. When i approached the service centre at Univercell, the service person talk was very cold and unfriendly. Never expected such a bad response from a dealer shop of high profile mobile brand like. Again after 2 hours of persuasion, they asked me to shuttle to Velacherry showroom of Univercell and talk to them. When we approached the velacherry show room, they again made us wait for a long time and finally agreed to make a jobsheet to Nokia. The response like this from dealers of Nokia is totally irritating, they are not even ready to look into the issue and right away dispensing off as the customers fault and not ready to take it as apossibility of manufacturing defect. I hope you understand the customers frame of mind after purchasing it for 8.5k and immediately finding that its a faulty piece. I request you to look into this issue. I have also attached the battery model and handsfree set along with the mobile unit.

A power surge (voltage spike) will NOT cause a cracked LCD! The device is protected by a circuit that will fail (causing an open circuit on the charger input) at anything above 18 volts therforeprotecting anything ele in the phone including the LCD. The LCD failure will co-incedental possibly due to a weak LCD, thermal shock or physical damage. If the glass of the LCD is intact and the LCD has simply "leaked" internally and there is no sign of external damag to the phone then Nokia normaly cover that under warranty otherwise they will consider it customer damage (as 99.9999% of it always is) and not cover it under warranty! I am not saying that this particular occurence is customer damage but it is rare to be anything else!

Brand New Iphone 5s Home Screen display defect

Here goes my ordeal with my Iphone 5s upgrade
After waiting in line for over an hour I purchased the Iphone 5s yesterday at Best Buy (Stonebriar, Frisco, TX). Later that evening, I noticed that when the time was 5:36, the home screen display was not showing the digit 6. Instead it showed a blur. I then changed the time manually to 6:36 and then to 6:43 and each time there was a digit 6 the display showed a blur instead. I must note that the phone was sitting in the grass which was a little moist (which I believe was the causing the issue). I immediately went back to the Best Buy location where I purchased the phone and requested a replacement after showing the defect. The store manager wanted me to wait in the line and I refused to do so (they sold me a defective phone so I did not see a reason why I had to go in that line all over again when it was just a replacement!). Anyways, after a tiff with the manager I left that store with my defective phone.
Next day, I went to the Apple store (Willowbend mall, Plano). I was greeted by genteleman at the entrance of the store who nicely asked if he could help. The moment I told him I suspected my new Iphone 5s was defective he said 'What!!' and made an expression of disbilief. Funny! I was asked to go to another peson who was standing and waving his hand further inside the store. I go to him and explain to him the problem and when I try to demonstrate it does not happen! Oh dear! Luckily I had enough screenshots in store and I showed them all to the store clerk. He then tells me that he can take the phone in for me and get it 'repaired'! In disbilief I ask him if he meant 'Replaced'? He says no, they will try to repair it first - he further speculates saying they will try a restore or maybe a front glass replacement and that if they still can't fix it, Apple will then replace the phone. In exasperation I tried to explain to him that the problem happened yesterday and then today it can't doesn't seem to happen, while adding that it is a brand NEW phone I purchased less than 24 hours ago and that I still am under the 14 day time-frame. I explain to him kindly that I would not be able to verify the fix (Apple does a restore or even changes the glass and returns me the phone and I must believe that the problem was fixed?? - Hel No!) and its not so nice to hear from Apple that they can't take responsibility for a defective product. He kindly says sorry and explains that it is policy and that they have to try to repair first. Oh how I wish I could've gotten Apple to sign my policy document for my money...sigh..don't work like that! So I left Apple and ran across to Best Buy mobile store asking for a replacement. The guy says Best Buy mother store and Best Buy Mobile store keep there own stock during holidays and he can't help. Sweet! I drive down 10 miles and go to a different Best Buy 'Mother' store and of course I'm asked to stand in the line. I swallow my pride and become a part of the line. My turn comes and again I explain the problem and of course the Best Buy clerk says 'Did you try a restore?' What!! Anyways, after a bit of reasoning (cribbing) with a couple of Best Buy agents, I was able to get them to replace my Iphone 5s (and of course they didn't have a gold color so I had to settle for the space gray..not a big deal though as long as this one is not defective also!)
So anybody had this display issue? Issue with Apple customer service?
Rs,
GH

Well they offered to do everything they could to work with you on the device....You are right in saying that the offered what they 'could'. Unfortunately what they could was tied by company policy.
Just like being human there are times things just go wrong- 2 out 2 IPhones 5s in 2 days! I hope people are doing better :-p
You fought against people at the store level who have /zero/ control over policy and had their hands tied by what theri bosses tell them to do. Agreed. I left instead of fighting. Unfortunately they are the first line of support and a manager maybe as far I'd get. Would love to chat with Steve Jobs but I guess now there is only one way for that :-p
They not only rushed you to get service to repair the device but you didn't even do any troubleshooting of your own to try to repair it. Now what if a restore had fixed your issue, you would have kept your device, your color, and what you paid for... - I disagree. If you read my original post, the problem happened the same evening I bought the phone. When I went to Apple I was not able to reproduce the issue. So you tell me how do I verify that restore fixed it? Wait and watch? After 14 days I can't even return the phone. The other speculation made by the rep was changing the glass. I would not try that for obvious reasons.
Why /wouldn't/ you try to repair something before spending your gas/time to replace it the moment something is amiss.
hmmm..
Now the 2nd new phone makes a rattling sound. Something is loose inside..I'd rather spend gas/time and return it than get them 'repair' it or give me a refurbished phone! Why? Because I can at this point and still get a new one with possibly no defects(fingers crossed) or I could find a company that makes better quality products :-p

Is my Playstation 3D Display Defective?

I barely received my Playstation 3D Display ~2 weeks ago.
For the first 2 days, my screen would go black for a second or two while playing a game. This happened 4 times within 2 days. Recently It's happened 3 times back to back, literally 5 seconds apart. And maybe another 2-3 times. The sound seems to play fine when the screen goes black.
Also, one time I was playing a game and switched one of the sound presets. I switched to Dynamic and the audio immediately started crackling and screeching loudly. I switched it back to Standard and haven't tried to switch the settings since because I'm scared of the speakers breaking. As well as the fact that I use headphones for gaming, but it sucks because I wanted to use the speakers for movies and TV.
Is mine defective? I read that some people had their display completely fail on them after a few days.

Nokia E7 Design Defect

Dear Team,
I have complaint against Nokia. I have purchased a Nokia E7 handset on 04th July 2011 from Mobile Store, Gwalior and it is under warranty.
I believe there is a design defect in the mobile slider mechanism. I found it broken one day. The slider's hinge is broken, which to a customer like me looks like a minor repair / replacement. I requested the executive to replace the mobile or repair the defect. I have been asked that the repair would not be covered and it would be charged at Rs 8890.00. Even after requesting Mr Sunil (Manager at Nokia Care) he said that defect is not covered under warranty. I was surprised.
I requested the executive to give me in writing that this part is not covered under warranty but she refused.
I request Consumer court to look into this mater please. I want a replacement of the phone / slider. I don't understand how these parts are not covered under warranty. How can Nokia care center demand for Rs 8890.00 for small part of a mobile that cost Rs 25,000.00 (Approx.) and is under warranty.

Nokia E52 display caller's name and contact pictur...

Can someone advise me on possible problem with my E52 - I am very pleased with most aspects of the phone but it is not showing the name of the caller or the contact picture when I receive a call (just the number).
Surely it is standard for every Nokia phone to show name of caller? I know S Ericsson phones show name and picture for both call and text. Nokias should at lease display the name?
Can anyone please advise on this?
Thanks

Nokia E6 display blank freeze

Driving back home today I noticed that whilst my E6 connected to my bluetooth handsfree, it didnt change profile to car but remained on default. Usually it does as I set it in the accessories options. Anyway I heard a new sms arrive and soon after stopped at home and went to check. I tried unlocking the phone both with pressing the d pad and flicking the side slide, but the display remained blank. I tried the power button and again nothing. I eventually resorted to removing the battery and rebooting. Seemed ok. Not sure why it did this? Anyone else had similar?

Hello I purchased my nokia e6 on 8th september 2011 and since then the phone keep freezing up on me. I started using skype two days ago and the phone turns black and its frozen. And it restarts or i have to force restart it. Please help...is there a update for this problem?

Nokia 5230 display distorted!

After updating to the Nokia 5230 latest firmware version (V21.0.004), whenever the mobile receives a new SMS or call the display is showing up distorted (Snapshot included as attachment, take a look!). This is happening randomly may be every 4 out of 10 occasions. Not just when receiving the call or SMS but also when i activate the touchscreen by touchin it for performing any task. I have to either lock & unlock the touch pad to regain the display or wait till the mobile goes into standby after light time-out.
Is there any option for me to revert back to the recent old firmware version (V20.0.005)?
How to get rid of this? I already tried reinstalling the latest firmware again twice but to no avail. This is the first time such an issue surfaced in my mobile usage.
I appreciate your response.
Thanks!

Hi, unfortunately it is not possible to roll back to earlier fw.
If you've tried to reinstall the fw, there isn't much more to do other than take it to a Nokia care point as this seems to be a fault only they can repair.
I've seen quite a few posts on this matter, and some of the users reporting such faults happened after changing their displays themselvs voiding their warranty, earlier (before updating). I'm not saying that is what you've done, but just to let you know.
The " funny" thing is that this thing seems to happen often while updating, so it could of course be software related.
If youre up to it, you could perform a soft reset to clear your phonememory and start out fresh, but it's unlikely that this will helps. If you choose to do so, you will have to back up whatever you need from your phone memory as this manouver wipes contacts, messages, apps installed on the phone memory etc.
If not, you will have to see a nokia care point, and you probably have to do it anyway!

MacBook Pro display defect?

Hi!
I brought my first gen core2duo 15" MacBook Pro (March 2007.. I think) to an Apple store genius bar today. It has the SAME defect as shown in pics in this thread: http://discussions.apple.com/thread.jspa?messageID=9955601
Unfortunately, I did not take pics of mine. I am a paraplegic for life, high level, wheelchair, and get bed ridden a lot, so the MBP has been a good friend. But, I was called a liar at the sotre today, and told that there was no way that the damage was due to anything but water damage, and therefor AppleCare would not cover it. I was so ticked off, and had no idea what to do. I asked them to please send it in, and that way I could have official documentation at least.
I have not ever had any type of liquid anywhere near my MBP. My apartment is small, and kept at 65-72 degrees F, low humidity. It is only used when I am stuck in bed, sometimes for a day or three. It sits on a shelf at night to charge, and gets placed on a hospital table for me to use. It has gone nowhere else, never been abused, dropped, etc. Almost like new!
It also has the battery issue (battery shows charged, but MBP will simply shut off, even with more than half a charge showing!), and the dvd drive does not write properly all the time (fails about 75-80% of the time). They said the battery simply ran out of life, not covered. And the dvd drive.. if they determine the display to be liquid damage, the dvd drive will not be tested. They also said that they will simply and ONLY open it, turn it on, look at the screen, and immediately assess it as being liquid damage. WHAT?!?!?
Are there any other occurrences of this... defect? I will gladly take a polygraph. It is NOT water/liquid damage, but no one at the store would believe me. I had a friend bring me there today, and they are ready to sell their MBP and iphone now after the horrible treatment. Any help in tracking down other cases would be HUGELY appreciated! Thank you!

I'm sorry to hear about the trouble you are having. It seems you are dealing with a less than normal quality level Apple store. You need to contact Apple Customer Relations at: (800) 767-2775. These are not the same folks that you would normally talk to for support questions and they have a bit more authority in these matters. Water damage can not definitively be determined without opening up the machine. Even if there is something on the surface of your machine caused by water or other fluid, that does not automatically mean it went into your machine and caused a problem. They need to examine the machine to make that determination. Just be aware... just as in the post you linked to... it does "appear" to be similar to water damage. So that is what they are going to think first. If you are sure it is not due to water damage, you need to stand your ground. But be understanding in that their first impression was the problem was caused by water or other fluid.
