Bright spot or spots on display / LCD
 
Hi guys,

suddenly a bright spot appeared on my display. It is best visible with a bright background, e.g. terminal. I would say it has 1/6 the size of a finger nail, so it is not only a single pixel, but more a real spot. It is simple brighter then the rest of the display.
Anyone an idea what has happened or has the same problem?

Hi

I have two of those "chickenpoxes"! :mad:
I have not yet asked Nokias opinion about these "spots"...

Devil: Are resistive touchscreens "new inventions"? I don't think so... but I got the point shouldn't buy yet that "chickenpox device"...

I had 2 on my first device. Swapped it out. I'm a little let down by the screen build quality tbh. At least I'm not as sensitive as the guy who's dealbreaker was 'dead pixels' that you could only see by cycling colors and using a magnifying glass!

my n810 has this, glad my n900 doesn't. its quite annoying, try to see if nokia will swap the screen out for you.

Re: Bright spot on display
 
Any idea, what is causing this? Too much pressure on the display? I know that there wasn't any spot at the beginning. Now actually a small second one appeared.

Re: Bright spot on display
 
Got this too, it just appeared out of nowhere a couple of weeks ago but I have no idea what caused it. The device wasn't dropped or anything like that, the only thing I can think of that may be relevant is that I used it outdoors in relatively low (~ -15C) temperatures a few times (but I can't find any operating temperature specs anywhere).

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

Re: Bright spot on display
 
I have two of those spots one bright, and the other one a little less bright.

If it's possible I'm going to send it back for a replacement.

I have the "[Bug 6334] random HW watchdog reboots" on my device as well that is quite annoying.

Re: Bright spot on display
 
I just noticed two brighter spots on my display too and they are visible only on brighter colors.

I need to return my device too. Damn, everything else was working nicely.

Can someone take a picture of these bright spots?

NotTheMessiah 2010-01-07 22:16

Re: Bright spot on display
 
mine developed one of these today. only about 3mm and is not an even shape, kinda banana shaped. i *thought* it might have been caused when i removed my invisible shield screen protector. it was pretty well fixed and tugged the screen a fair bit to the point where it could see it bowing a little! howver, after reading this thread seems like it may just be coincident. dont really want to have to send it in for a replacement since everything else is perfect. if anyone finds a way to remedy the problem please please post.

Re: Bright spot on display
 
I purchased my n900 from amazon.com. After about a week of using it I got a small bright spot on the upper right corner of the screen. It was exact size and shape of a grain of rice. So I started looking around the screen and also found a dead pixel on the lower right side of the screen. I called amazon and they send me a replacement overnight expressed and it is perfect. No blemishes, screen is perfectly and evenly lit, and the slide seems stiffer.

Return it immediately and get another one.

Re: Bright spot on display
 
wow i thought i was the only one with this problem mine is on the right upper side as well and only really visible on white backgrounds it has grown slightly with a bit developing right at the top of it now also have a smaller less noticable one on the bottom right it isnt making my screen unusable but i do notice it and it bugs me would love a cure dont fancy sending it off to get repaired

Re: Bright spot on display

Re: Bright spot on display
 
I've noticed one of these spot over the last couple of days. Sure I would have noticed it earlier if it had been there. Once you see it you can't stop looking at it!. However, today I've convinced myself it's not as bright as yesterday!
Will try and take it back but I've had it since end November so it will probably be a repair job :(

Edit: Just thinking, could it be something to do with the cold weather?

same here, it looks to me like its fading but my gf doesnt think so. will keep an eye on it tho. i have another issue too since removing my screen protector and that is that my touch screen soumetimes makes a clicking/crunching sound. quite worrying really tho it seems to be working fine.

Re: Bright spot on display
 
Probably not cold weather...cold weather will cause a "laggyness" or "motion blur" effect on an LCD that should go away at normal temperatures.

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."

Re: Bright spot on display
 
Mine is from first retail batch, it developed 2 of those spots 2 weeks ago. A little frustrating, but for the moment I will keep them because everything else works almost flawlessly. Let's hope it is not a first simptom of something worst - I had a WSOD 770...

Probably nothing to worry about, just the parts shifting a bit as you apply pressure. My old Treo 650's case screws would "loosen up" after a few months of heavy use and I'd start to get crunching and creaking sounds when typing or touching the screen. I'd just tighten the screws again (you need to be careful not to overtighten anything with a plastic case - it's easy to strip threads or cause a crack) until the parts all fit tightly together. Haven't had that problem on my Treo since I started using a hard clear case though.

I do not have any spots or stuck/dead pixels, but I have had the touch screen clicking. I have all sounds turned off; it's not that. When it happens I noticed that on a certain area of the screen if I click and drag--that's when the screen physically clicks. As if two layers aren't touching and a ripple builds up, then snaps. Probably makes no sense. But there you are.

Has anybody spoken to nokia about this issue? Does it fall under warranty?

meychi 2010-01-15 20:45

Re: Bright spot on display
 
I took my N900 to repairs last friday (Verkkokauppa.com, Finland) and today i got it back. They changed the screen with no extra costs or questions. Yay! I guess that if the spot is visible, they will change it if you haven't broken it yourself (no visible damages on screen).

I had it visible on bright colors like terminal or google.com.

Mine is exactly the same. I guess I'll drop the phone to Nokia care center somewhere here in Helsinki now that I've read you got it repaired under warranty :) So thanks for the info.

meychi 2010-01-15 21:12

Re: Bright spot on display
 
If you want to reduce the time on repairs, first get the warranty receipt from the store you bought it and then take it to the actual service center yourself. Usually they send the devices to repairs via post office. This is what they told me at Verkkokauppa.com. :)

Mine was at Anglo Service or something like that in Helsinki.

My N900 with bright white spots
 
Hi all, I wanted to ask something.

I have noticed when the background is white, in the right upper section of the screen, there is a 2 small spots ( like 5x5 mm) that are way brighter then the rest of the screen.

Its not a dead pixel, but a group of pixels that display brighter. its not very noticeable, but when you are browsing pages which are mostly white, like google or gmail, you can see those spots easy.

I tried to print screen that, but on print screen is not noticeable.

Anyone have similar problem maybe ?????????????

GID123 2010-02-02 18:48

Re: My N900 with bright white spots
 
no...i just browse google and did not see the 2 small spots. Maybe bad
pixel on your n900.

Re: My N900 with bright white spots
 
I have this problem too, I think they are pressure marks caused by the case i have.

Catacylsm 2010-02-02 19:08

Re: My N900 with bright white spots
 
Interesting, could it also be potential moist inside of the screen? i know that could lead to some uneven lighting.

Re: My N900 with bright white spots
 
Curious, could this be the result of too much pressure?

No, it is not about the pressure, I notice this like 3 days after I bought my phone, and I dont have a case or something like that. And it is not like dead pixels or moist inside of the screen.

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

well, I quess that isn't more than in other similar products with their first iteration. and you should scale the problems with amount of actual problems.

and some items in your list are pure speculation. droid has random reboot issue too.

you'd expect that your expensive volkswagen golf has no issues because it costs at max about double to mazda 3. and lets not go to porsches at all.

hint: one of those has the least faults out of all cars in multiple researchs. you pay the price not because of zero possibility to issues, but for the fact that this issue will also be repaired within warranty..

back to topic: had one bright spot for the moment, havent seen it since. (and dont care either because apparently it doesnt affect display quality outside full white)
