Blue bright spot - might be dead pixel

Q: Blue bright spot - might be dead pixel

Hi,I bought hp pavilion 15-ab516 TX yesterday night and on using that night only at home I found a blue-green sparkling spot on my laptop screen. I restarted the machine twice to check if it persists or not. But it hasn't disappeared. On checking with the hp dealer initially he said it's common and he couldn't do anything. But later on he said I should call hp and they will direct him about the next step.What should I do to get it replaced? As I haven't used it at all and don't want a part to be replaced only.

Hi people,I have some issue with my screen on lenovo thinkpad t450. I bought it in Sweden recently (few months ago) and everything was fine, and then this morning this black spot of pixels showed up. It was not punched or something like that, it was on my desk the whole time.I tried to run JScreenFix.com on this place and also to massage it with a soft cloth but it seems that it just gets worse.The problem I have is that I am now in Serbia, and I have this international warranty, but only in one city in Serbia which is on the other part of the country.Also, I saw that there are service providers in my city, but I am not sure if they can fix me this as regular service with warranty.Do you maybe know how this functiones? Or have some tips how to solve this?

Hi everyone,I just received a super beautiful Lenovo Yoga 920 laptop, but quickly discovered a very ugly and disturbing thing.At first, I thought it is a dead (black) pixel. After playing around with different lighting / light exposure, I found out that this spot is  there even when the laptop is turned off.Laptop on, white background: super ugly black spotLaptop off, shade: not visibleLaptop on, sunlight: visible in a colour that can be best described as some shiny glass colour.I attached some pictures. They are all showing this same spot, with different light exposure.Gentle wiping/rubbing didn't help at all.It is right in the center of the screen, and super disturbing. It destroys the whole experience of this basically beautiful Yoga.Thanks for sharing ideas!

Hello So I bought a laptop for my mam today, literally about an hour ago. And said I would set it up for her but when I turned it on the first thing I noticed was a bright blue pixel up the top of the screen. I am very annoyed as it was brand new! While I know I can just bring it back and get a refund or exchange I would love to just be able to sort it if possible. Is it possible to fix a bright pixel? Or will it eventually just become a dead pixel? I really hope someone can help! Thanks in advance guys  Kind regards, Rox

The pictures show it. Some days the area on the right on is dark, sometimes it is bright.  The second issue is that the screen won't always come on as bright as it should. This always happens when the computer has gone to sleep, and when I try to wake it the brightness looks turned all the way down, even though the computer thinks it is at 100% brightness.

I have a 2014 era Lenovo X1 Carbon (20A7 -- not sure if it's 2nd or 3rd generation -- it's the one with the touchbar along the top of the keyboard)I get a number of bright white spots on my display. I had the screen replaced and this fixed the problem, but only temporarily. The spots came back exactly as before. Today, the IBM tech came in to fix the touchpad and I had him look at the display a second time. He removed the screen from the laptop lid to see if something was pressing against the display -- which would explain why two different displays would exhibit the same problem over time. Behind the screen is what looks to be an antenna that runs diagonally from about an inch down from upper left to the lower right corner. Sure enough, the white spots are appearing along this diagonal. When I run my finger across the antenna, I felt it was a bit lumpy in the area of the white spots with some speck of debris exactly behind where the brightest spot is. This makes me wonder if the irregularity in the antenna installation, as subtle as it is, is causing the backlight to become damaged over time.Lenovo seem inclined to just replace the display, but this doesn't seem to be the complete remedy. The mis-installation of the antenna in the backlid is the root cause of the problem

I have a Thinkpad Yoga 12, and on the display, a small bright spot develops when the device is on long enough. It only seems to be easily visible on lighter colors and webpages, midtones and dark colors/blacks doesn't show it. When the device is first booted, nothing appears on the display and everything looks uniform, but gradually, a light spot develops. From seeing previous forum posts about light spots, they say it's caused either through faults in the display, pressure, impact, or heat, and judging by how it takes a few minutes for the spot to form, I'd imagine it comes from heat or something under the display(?)If the device is out of warranty, is there any way of fixing this?

Hello,

I recently buy a fujitsu laptop with preloaded Windows 7 Home Basic.

After using it for a while, I noticed that there is a Bright pixel in upper left corner of the windows desktop. I'm sure it is not a deadpixel because if I drag a window to that pixel, the pixel will display the right color.

I think it is software related. I already read other thread that mentioning this problem, but he already solved it by disabling an AOL software. But the case here is that I'm not using that AOL software.

the Bright pixel will disappear if I restart the laptop, but it suddenly appear again when I open the "desktop Background" menu.

ANyone can help me? thanx..

A dead pixel will always be the same, just less noticeable with different backgrounds. If your description is correct, I doubt that it is a dead pixel.

I have the same problem. It began with to bright spots in the lower part of the panel, one in the left and one in the right corner. They came from one day to the other; now, a few days later, two, larger, non-circular blothes have emerged in the centre-left of the screen. The PC is not even a month old.
 
I did the pixel test mentioned - and it does not appear to be faulty pixels; the blotches remain visible with all colours, except for black, which is basically all the pixels turned off. The shape and size of the blotches also point to something else than pixel error.
 
Any idea what this might be? It is certainly getting worse by the day.

I am encounteringa problem with the screen of my HP Spectre x360. I have a few very small, white "bright" spots on my screen that show up especially badly on all white screens. I first notice them within the first few weeks of having my new laptop, but because of school I could ill-afford to send it in or spend any time trying to get any customer service. The laptop is great, but these marks are annoying and are unimpressive given the amount paid for a "top-end" laptop. I was told by an HP Technical Support technician that fixing such marks would not be covered by warranty as they would be "accidental damage", but the hinges on the Spectre are covered by warranty. I found this curious as both work together to make the "2-in-1" tablet-laptop functionality. I've hardly even used the touchscreen and always been very delicate with the laptop. Additionally, it was suggested that the pressure must have been applied from the back of the laptop, which is curious as one of the selling features is that it has a solid aluminum shell (and there are no visible marks of any kind on the back). Calling this accidental damage is a pretty terrible way of trying to skirt standing behind your products: it is a touchscreen computer, the touchscreen should not be damaged from occasional use. I have a touchscreen phone that I am constantly pressing and in 3 years have never had a similar mark. I got this with my Spectre 1 month in from almost never touching it (and if I was, it ...

I have the same issue, has a solution been found? I have a rather large mark, like the edges of a rounded square of around 5 cm high to the left of the centre of the screen, where the HP logo starts on the back. It looks like there is something behind the screen shimmering through...I've been having various issues since I've had the laptop, one of them being that it is crooked, another is that on start-up, it'll flash some sort of static lines (like a screen/graphics malfunction) for a second or so before going to Windows. For a while it also flashed these lines at random while I was working, but I suspect that may have been a driver issue.On the whole, I'm rather happy with the laptop, but the different issues are very worrying, I don't trust that it will last very long, especially because there seem to be issues with the build quality. For a laptop this expensive, I had expected much better, especially since my HP Pavilion dm1, which was only 400? or so, lasted me a solid 4 yeard and never had any build issues whatsoever...

Hi,this is my second thread about an issue with my Spectre x360, only 3 months old.I send it to repair to HP the first time on 8th november 2016, and I had it back on 12 december 2016.The previous problem was a faulty display hinge. The HP support replaced the display entirely, the hinge and the wifi card.Today I noticed a strange behaviour on display backlighting. Yes, this looks like a issue with backlighting,not with pixel.Because the pixel changes its color and luminance correctly basing on what it's shown on the screen, but its BRIGHTER than others.Looking further, it's not just a pixel, it's a brighter spot, has nothing to do with pixels itself in my opinion.This is noticeable with light colors, on black/gray and darker colors it isn't visible.I'm starting to wonder about quality of spare parts and in general with HP products and their engineering.I'm a bit disappointed because after spending 1500? for a premium product I had to send it to repair, and it stayed 1 month and more away, lost 1 month of warranty, and worst of all, I can't enjoy my product.Today an issue showed again.I work in photography and I'm really starting to wonder if I have to consider to sell my Spectre x360 and looking to other manfacturers for my personal/work laptop choice.Attached there's a photo of the problem.

Hi, I've had my Spectre x360 for two months now and noticed this just recently. The reason I noticed was that it was the first time I had a completely white screen, and the defect became very apparent. Spot stays stationary on screen and is most apparent with white or grey backgrounds, and is not very noticeable on blacks. The machine has been handled very delicately and not transported so it's certainly not damage. Will HP replace the unit for me? This is the second Spectre X360 I've had, first had WiFi and track pad problems and I am beginning to get quite frustrated.

Hello everyone, this is my first message here, and by the way, I'd like to apologize for my poor english ;] Yesterday I have noticed a problem with the display in my X220 (type 4290-W1B). There is a small, white spot (about 1 mm diameter), clearly visible on the screen. It doesn't look like a normal bad pixel, but like a problem with the background light, or something. It is not visible when black color is displayed. The laptop was bought about 3 months ago and everything was OK until yesterday.I have attached some pictures of this dot, but it is difficult to capture it with the camera (it is much more visible in real). I have marked the spot (it is in the middle of the circle). The pics are in high resolution so you can zoom in.  What should I do now? I have heard , that the Lenovo bad pixel policy is 3 bad pixel per display..

Is your monitor LCD or LED?
I think you have run-of-the-mill dead or stuck pixels. Usually is a monitor problem, I heard some Government thing called the "Dead Pixel Policy" but it only applies to brand new monitors or monitors that are still under warranty with dead pixels. There are some sites that host software/programs to diagnose dead pixels by putting different colored slides on the screen, like this program here:
InjuredPixels 2.1 Download - Freeware Files.com - Utilities Category

There are also programs to attempt the fix of stuck pixels. If it's new monitor or still under warranty with dead pixels than you will get a new replacement thanks to the Dead Pixel Policy.

I'm pretty sure it was NOT missed by QA because it glows like a laser beam in the dark and a dead pixel would not develop while in transit!           I'm going to contact Lenovo post sales tomorrow and really hoping something can be done. I know some of you will consider this as another guy who got a dead pixel rant, but man, when someone spend this amount of cash, and I'm not rich, I would at least expect to receive a non-defective product.

As each OEM has acceptable pixel standards, running pixel test would help.

Apparently there is a dead spot in my room where I've had my comp. for the last couple months. It had been working fine until mid-june, when our router died. After we replaced the router my room was painted dark blue over an existing peach color, with regular wall paint. This paint does not (hopefully) contain lead. When we painted my room, I moved my 50 watt stereo system behind the comp. The wireless worked fine for a couple weeks after the move, and then just sputtered out. I have noticed that the signal gets weaker as i go into my room, and when I am at the far corner of the room (near the stereo, some exacto knives, and a desk lamp with a 13 watt halogen light bulb) it does not work at all. Yet on the other side of the house, farther away from the router, I get a good-low, yet fast signal.

Note: the computer that seems to be permanent is running 32bit version. my dads 32bit version doesn't have the same problem. any ideas?

Hi All,  I have a x1 2018 version bought last November. I have taken care of it very well, but I just found a dead pixel on the screen last week. I made the call to the service and sent it to them. But they just called me and told me the repair is not covered by the warranty because they determined that the damage was made by the customer (CID). The cost of repair is more than $300. My x1 has a 3-year limited warranty. Here, I wanna ask for the community or anyone that may meet a similar situation before. How did they believe that the damage is made by me but not a problem of their own product? I am a Thinkpad lover of more than 10 years and it is the first time they refuse to fix a screen and said it is my problem.  Thanks all. I attached the pic of the dead pixel here for your reference. Do you guys believe that such a tiny dead pixel can be made by a big guy?

Hi Does anyone know if the Lenovo warranty covers a stuck/dead pixel? It might not look like a big deal, but once you notice, you can't unsee it and, personally, I think it's a bit of a shame really that this happens with a +1K laptop after only 2-3 months. Thanks in advance

Just got my X1 yoga with OLED screen and after less than a week with around three hours total use - no pen or touching - when I turned it on today it had a bright blue single pixel.  I tried everything I could find on-line but there it is, unchanged and glowing as strong as ever.  Any ideas.  Or is this a situation where I just focus on getting a replacement.

Hello. I'm just trying to get a definitive answer to my problem. I have a black spot on my taskbar and from my search here on SF and Googling, the difference between a stuck pixel and a dead one is that a stuck pixel will be white or a colour while a dead pixel will be black. This leads me to my conclusion that what I have is a dead pixel (my warranty ran out about 2 weeks ago so the timing seems right).

The majority of opinions is that there is no fix for a dead pixel. When I Google, however, there are 2 or 3 hits that claim there is a fix. Frankly, I am doubtful about these claims, but I would like to get the opinion of some of the people here at SF as I trust the knowledge of the people here the most.

So, to sum up, am I correct about the dead pixel and is there a fix?

Thank You, David

A:How Can You Mend A Dead Pixel's Heart?

On an LCD/LED/TFT screen, each pixel (or, rather, group of 3 sub-pixels since each pixel is actually comprised of a red, green, and blue element) is controlled by a transistor array. If we think of these transistors as switches, when they are open the appropriate sub-pixel is turned off and no light is admitted through. Conversely, when they are closed, the appropriate sub-pixel is turned on and light is allowed through, the colour of which is determined by the sub-pixel.

We use the terms dead pixel to refer to a pixel that is completely dead and shows no colour whatsoever, whereas a stuck pixel means that at least 1 of the 3 sub-pixels in that pixel group is permanently turned on (the others may, or may not, operate as normal). In both cases, the root cause is the same, this being a dead transistor or transistors (they can fail either open or short circuit).

Unfortunately, it is not generally possible to reactivate these transistors, once dead they stay dead. Some people say that by gently rubbing in the area of the dead/stuck pixel, it is possible to bring it back to life, whereas others maintain that by rapidly cycling the pixels surrounding the problematic one it is also possible to revive it. This may or may not work, and there is no guarantee either way.
