Nokia C7 Display problems/ scanlines effect

I was going to combine this with my other post, but seeing as the two issues are unrelatedm i decided to creat a new Topic.
So the phone is on the PR1.2 software.
The Screen has a flickering effect, especially if you set the brightness to the lowest and block the ambient light sensor to simulate darkness, which is where I noticed the flickering scanlines the most, on light/white backgrounds, like you get on old TV's?. Also, sometimes touching the screen causes a slight change in the hue/colour of light backgrounds, going from a blue-ish white to slightly yellow.
Is this a manufacturing defect? Do any other C7 users experience this?

I have bought this phone last week..its an amazing phone. However, i could see a thin horizontal line on top of my screen just below the secondary camera and the light sensor... that is very much visible on lighter backgrounds... is this a manufacturing defect can it be fixed??
Please suggest!!
I do not think it is something you need to worry about. I have noticed the same on my C7 and it does not really bother me. I think it makes it more beautiful

Nokia 73 display problem

Hi! I am a new user here though I purchased my Nokia N73 more than one and a half year back here in New Delhi, India.
During the last month or so my N73 is having some display problems. Sometimes on pressing any button from the rest state, a wavy pattern appears on the display and I am not able to read anything. Sometimes the pattern appears when I receive an incoming call even without pressing the 'accept' button. The pattern continues for about 30 sec to 2 min. and then disappears on its own. Very occasionally, I have to open the back cover and remove the battery, then restart the phone to correct the display.
I have updated the firmware on the phone yesterday. There appears to be a reduction in the frequency of the occurences of the problem though it still persists.
What could be the reason for the problem and what could be the solution? I would be grateful for any advice.

Hi Akb18,
I would think this is going to be a hardware fault rather then a software fault.
It might be an actual LCD fault or where the LCD plugs into the circuit board.
The best thing is to take it to a Nokia Care Point.
You can find the nearest NCP to you at the Store Locator for the india area.

Nokia 6700 display problem

I bought a nokia 6700 about 6 weeks ago and used it without problems for about a week.
Since then I haven't used it.
Today I switched it on and the display seems corrupted - everything is displayed, but it looks as though it is trying to display text and graphics to a different resolution to the screen, so everything is hard to read. It looks more like a software issue rather than a damaged screen (and it has been sitting in a box for several weeks, so there has been nil scope for physical damage).
Any ideas anyone?

hi there, there have been a number of reports about the 6700 classic detailing display corruption or along similar lines. i would suggest that you follow the advice regarding Nokia Care Centre i have provided in similar threads: /discussions/board/message?board.id=phones&message.id=61791#M61791
please throw kudos our way, it would mean a lot to us

Nokia N81 Display Problem?

Hi Guys, I am facing this problem with my Nokia N81 just starting from today. Whenever, I slide it to access the keypad, it's screen turns corrupted with funky lines and random things on the screen. What could be the problem? Could it be the hardware or software? Pls HELP...

probably the flexi cable. It doesn't sound like software at all to me. You should take your phone to a care center to have it checked out. The flexi cables are not too expensive

Plz help to Slove Nokia 5800Xm Display Problem

Hi,
Well I have this phone for over 2 years now and now I have a big problem with it that won't go away. The screen goes completely into stripes and is unreadable. It just showed up like that and it's always when I use the screen-lock button (slide button on the side) that this happens and then stays. Once I got rid of it by rebooting the phone almost 10 times or turning it of a whole day but as soon as I use the screen-lock button (slide button on the side) it comes back.

Although you would have to backup essential data first, you would first need to exclude any possible software related issues by either carrying out a "hard reset" and/or re-installing existing device soiftware via Nokia Suite.

Display problem in Nokia XL

I purchased a Nokia XL last month (Purchased online). After a normal usage of almost 15 days, during office hours, the Display got white vertical lines. If you lock the screen and unlock after some time , the display looks clear, after some time the white vertical lines start coming on the display.
is there any hardware problem are any settings problem. The place where i am staying is 75 KM away from the nearest nokia care center.
Any one faced the same issue of Display problem in XL
please reply....
Thanks in advance

This may be software problem. For now, follow instructions given by @dimoff
Reset your phone, it will delete entire data on your device. So create a backup of your data before resetting.

Nokia 5800 XM Display Problem

I have Nokia 5800 XM with its version updated to V 21.0.025. I had purchased this phone in Jan 2009 and had no major issues till yesterday.
Today when I unlocked the phone I suddenly saw a scrambled greyish display with flickring lines.
I locked & unlocked the phone again, I got back the normal screen. I repeated locking & unlocking to check whether problem still persist or not, unfortunately the scrambled display showed up every alternate time I locked & unlocked the phone.
I thought, restarting the phone will get rid of this problem, but restart didn't solve the problem.
Then I thought of resetting the phone to its factory setting. I restored the phone to its original settings through *#7370# code but it was a futile effort.
I checked about this issue on the web and found that lot of other people are also facing the same issue.
for instance check the following video link which exactly demonstrates this display problem:
http://www.youtube.com/watch?v=Q9A7yd-2eeA
Now after a lot of reading on the web, I feel the display problem is a hardware issue and will get solved by Nokia Care people only.
I am really disappointed with Nokia for such a poor build quality of this phone.
I trusted Nokia for its superior build quality and durability and opted for this phone but it doesn't lived to its expectations.
Now lets see what happens when I take this phone to Nokia Care...

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

Hi G5 Gurus,
The display problem first, we all know when screen savers display, a click on the mouse will bring you back to the active desktop, this was how it worked., but now, sometimes a click cause the G5 to sleep!
As for the sleep, I dare not to put it to sleep these days, because I am afriad it may cause a fire by over heating. Sometmes, actually four times in the past few months, my G5 could wake up by itself, followed by a extrem high speed running of the cooling fan, it sounded like a hair dryer running in the same room. Sometimes the sreen could light up, just like real wake up, sometimes, it was black. No clicks the mouse or keyboeard could bring it back to normal, I had to press and hold the power button to turn it off.
This crazy problem happened for the first time last summer, a dead hard disk was the cost. Apple replaced it, but failed to detect the cooling or power or display problem. I was given one month extended free service, but right after its end, the problem was back and happened even more often.
Please let me know if any of you had the same problem and please advise what to do.
100s Gs of thanks.

I have the EXACT same problem. In fact, I could not have described it better myself. What gives? I brought it in to the "genius" bar and they repolaced the power supply free of charge but the problem is still there. I noticed they ordered a new logic board but did not end up replacing it after all. Did you have yours replaced and did it work? Is this a known issue?

Hi La teller,
Thank you for your reply. The 'genius' here in London only replace the dead hard disk, which I belive was a victim of this problem. I was told they couldn't find anything wrong with the power supply or the cooling system.
Now at lest I know I am not the only bad luck guy. Let's wait and see if others are having the same problem. I am not sure if this is a known issue to Apple, even if it is, it may take years before they can offer a recall or free repaire. I noticed that some G5s have already been suffering from power problems and a free repaire was offered.
Thank you again and hope Apple can take our concerns into their consideration soon.

Hello,
I'm also having this problem (fan running, won't come out of sleep), just spoke with an apple care rep. He confirmed my suspition that it was software, not hardware as I have just had the logic board and power supply replaced.
His suggestions were to:
1. Run disk repair from the startup CD
try running OS X from a firewire drive and see if the same behavior happens or
perform and archive and install.
When the fan starts to run like that it means the OS is not communicating with the hardware properly. The OS could be somewhat corrupt if you were having hardware issues beforehand, hence the need for a reinstall. I will be performing an archive and install after the disk repair, I'll let you know if it fixes the problem!

Hi Stopha6,
Thank you for your message. I never imagined it could be a software issue, cos it looked so hardware.
Please keep me updated with your progress.
By the way, as I said in my old posts, a hard disk went dead when this happened for the very first time, how do you read this?
Thank you.

Hi Stopha6,
After reading your reply again, I realized that the system had already been reinstalled. As I said when it happened for the first time, the hard disk died with it, which was replaced, of course with a new OS X, but the same problem is still happening. May this suggest that it is not just a software problem? Thank you. Songyan

The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on. The screen-saver and sleep problem you describe sounds like something that may just happen on accident. But this sounds mostly like a software problem. Try making sure to always quit all non-apple products and see if anything changes.

Thank you, Ag-Nate. I will try as you adivised but I con't think the fans were activeted my intensive CPU using. In most of the cases, the problems happened when the Mac was sleeping, when the minimum CPU were being used.

"The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on."
That's only partly right. A hard-working process will make the fans run at high speed, of course.
But, the OS is in touch with the firmware of the iMac, telling it how to run the fans, based upon information the OS X kernel is getting about the state of the hardware.
If the firmware loses touch with the OS for some reason, and is not getting instructions on how to run the fan, it will default to running them at full blast, to be on the safe side (and this "full blast" fan mode is way louder than anything you'll generally experience during normal usage, I know from experience).
So it may not be so simple as a hard-working cpu process kicking the fans on.

Hi I have a 20" G5 imac it's about 18 months old and I am having the same problem, It freezes and the fan runs really loud. It's nothing to do with software as my I.T. guy has done a complete re-install. All of our admin people have imacs of differring ages and the flat panels are all OK but every one of the G5s has had a booting problem. Some fell into the recall for replacement logic boards but the one I have at home is the newest and doesn't. I'm waiting for my apple reseller to get back to me, but it looks like it's the logic board and as none of the serial numbers fall into the recall, I'm expecting a big bill. I'm really disappointed as I've been a professional apple user for over 15 years and have grown to expect a certain amount of honesty and integrity from them. Looking at all of the discussion boards and the amount of people complaining of the same problem the logic boards are defective and apple should be replacing these free of charge.

Welcome to Apple Discussions!
As in the other thread I wrote:
Being from England, you may find the repair program under these pages:

Check both of them as they refer to different models.

First off, you'll get a wider audience who may be able to solve your problem. Secondly, responses to you won't confuse the original poster with solutions that don't apply to them. And thirdly, you'll know for certain whether or not a response applies to you.

I am having a very similar problem. My G5 imac has already had the logic board replaced from the leaking capacitor problem. 8 mos. later the power supply was replaced under the second recall program when it failed to start up.
It had been working now for almost a year, when about 3 mos. ago I started to experience the sudden dimming effect - if the display was untouched the screen would dim about 30% similar to a laptop in energy save mode. I checked and none of these types of options were set in the pref panes. At the same time I would have the iMac go to sleep after a while from non-use, and then when I tried to wake it it would stir for a few seconds and then go right back to sleep. It took 2-3 attempts to wake it up.
Then last week, as I tried to wake it, it just shut down instead completely. I had to hold the power button down to recycle it to get it to come back to life (3 times).
Today was it - I found what I thought was a sleeping iMac, but it will not power up at all. I opened the back cover and the power supply is working, but I cannot get the board to energize, I reset the PMU, but the #2 LED won't even blink. It is completely dead.
Basically every time I used this computer I held my breath that it would not work. After 2 recalls I still only get 9 mos. out of it? Apple is really starting to show it is like the "big" computer makers, the quality is going right down the tubes.
