I got 3 dead pixels (the whole time only mid grey) in the middle of the screen. The device isn't useless, but I can see it.

I have the Device since the beginning of December. So I have to bring it to a Nokia Care center. But a Week without Device?

I'm not sure. Is this the effort worth? :(

Re: Bright spot on display
 
possible cause :
oily traces on screen's backlighting diffuse system ( I do not know the english word/expression ) or some plastic support behind lcd was deformed by heat form a semiconductor IC or a smd too high so it touch the backlight system.
even a small deflection can cause differences of light.
after my n900 honeymoon :) i will disasemble it to investigate this.

i have same issue with my old FSC T830 after i wash screen with Isopropyl alcohol and it infiltrated behind lcd.
even I drying after complete pda and display dissasemble i don't get perfect clear screen.

Re: Bright spot on display
 
Yep, I have one too. Right in the center of my screen.

I think it's because screen material is not that good. Other then the touch sensitivity being good my screen is soft, clicks and scratches easily.

i have it on the right in the middle. noticed it a few times. kinda used to it. was very annoyed when i first saw it

Re: Bright spot on display
 
Damn. I just noticed that I have two brighter spots on the display. Not so bad, but have to take this to nokia care some day. I already had the same symptom with my fujitsu laptop. Though my laptop had it much worse. This is barely noticeable, but annoying enough.

The N900 seems to have a lot of hardware faults. Weak USB port, varying battery quality, varying CPU quality, memory chips that are easily disloged if it's dropped, and now bright spots...I gotta say you'd expect better quality for something so expensive. It's not a huge issue for power users and tinkerers but these issues would terrify an "Average Joe."

ya, that is true that n900 has a lot of hardware faults.. for example mine has 2 bright spots, 2-3 dead pixels...well that is not much noticeable, but I can see that coz I know where that is. And I am using the phone... And btw, my USB is working on 1.1 when i connect nokia to mass storage, and my all other USB sticks work on 2.0.. well, those are some small problems, but I wanted that top model from nokia work good, without this problems..


Maybe "Made in Korea" has something to do with this??

I purchased this from MPD in the UK - does anybody know what their turn around times are like for repairs / replacements?

Yep, it's true that Honda Accord have a lot of hardware faults... For example, my left headlight was badly calibrated, the clutch failed after just 3000 km, the exaust pipe had some weird deffect that choked the engine, and there were numerous problems with systems which I don't even know how to translate in English... Well, those are some small problems, but I wanted one of the top models from Honda to work good, without mentioned problems...

Yep, Honda sucks (tho it was voted as one of the most reliable car manufacturers on numerous occasions) and their Accord is a piece of shite (doesn't matter that it's been in the top 10 lists of reliability almost since its conception)...

Ya, thx for correcting my post, it is true MY nokia has some hardware issues, but not only mine as I and YOU can see on this forum.. So be realistic... I know that you and,,maybe,, 80-90% (or less??) of people got a good phone, but it is not so ideal as you think :)

Yup, you made a point here...a good point.. But nevermind of my hardware issues, I still like this phone and its the best one I ever had... so i dont care about those white spots and some dead pixel :)

Re: Bright spot on display
 
There are numerous possible screen defects (check HERE and HERE), and most of them fall under the warranty these days, so my advice to you is to check with your reseller if you can replace the device, or go straight to some Nokia's official service and ask them to replace your screen.

Judging by the experience of people that had problems with their screens, Nokia replaced them no questions asked.

Re: Bright spot on display
 
Well I just visited the local mobile care here in helsinki and the guy said that he thinks it might be moist. I hadn't backed up my phone yet, so I did not leave mine in yet. Though would not like to pay 25 euros to get said that its my fault and 130 euros for a new screen. though I'm positive I haven't done anything.

It is like on those 2 spots are brightness on like 140% and on rest of the screen brightness is 100%. Its strange :D

I have the same problem.

I have taken a picture and edited it, so you can see it (it doesn't show that well on pictures normally).

Does this seme to be a general problem? Does anybody know if this is covered by the warranty?

Re: My N900 with bright white spots
 
both myself and my n900 owning buddy have the white spots in the same place on our screens. must be the arrangement of the electronics inside!

Talk of these bright spots is worrying me, a bit like the USB socket problem... :(

Re: Bright spot or spots on display / LCD
 
I don't have this problem but This is really a shame for Nokia , It seems after the Nokia n97's disaster the quality control department is shut down completely , seriously .

Lots of creaks/stuck pixel/dead pixel/loose usb problems , They have to get their act together . It seems Nokia is avoiding to accept their mistakes as they usually do .

I'm just saying because it seems the quality of Nokia cellphones has decreased recently and I have been using Nokia cellphones for 8 years now .

Re: Bright spot or spots on display / LCD
 
i have those problems too!!! one stuck pixel and one bright spot on screen!!! People it's time to think about a class action versus Nokia! N97 was too bad. I decided to take the n900 but its a double shame!!! 600 euros for a shame and horrible hardware!!! class action please let give the value to our money and our rights!!!:(

wtf? class action?

did you even try to get it replaced?!?

it is unfortunate but it is quality deviation which can't be removed completely unless you (and all the others) have 6000 eur to spend to the device....

yes, I have the same problem. No, I don't think. Class actions shouldn't be used because manufacturer has a right to repair defect device and he doesn't have obligation to do something as impossible as removing every single defect unit before those ship.

just cool down, I didn't understand anything from the last paragraph.....

My spot is thankfully mostly in the window titlebar area so it only gets annoying in full screen mode.


Normal LCDs are not intended to be used under 0C. actually it's said that under -5C they should stop working.

Re: Bright spot or spots on display / LCD
 
guys, this is not always nokias fault. I would probably say the same thing as but, but recently, my job has forced me to learn more about reliability.
Nokia doesn't make the parts, they mostly assemble it. They order it from suppliers. The supplier then guarantees the screen with a failure rate of .4% and a n of 50000 (this is purely hypothetical). Nokia can't test those devices as their normal running time is 24h/day. So there's no accelerated test to be performed to see how the screen performs after 3-4-5-months.
The usb part was their fault, but this one, no.
Nokia should change your device without any discussions since all the costs will be payed by the display manufacturer or his insurance, but Nokia should really think about changing that supplier since it's bad publicity.

All the companies do the same, choose the one that it's the cheapest, but has the characteristics fitting their requirements.
trust me they don't want this, it costs them more money to change your product after sale then changing it in the factory, which cost more than changing it at the supplier.
