Are dead or stuck pixels common, i just got a samsung 5271 6 days ago and noticed i already have a dead pixel, is this a common thing with lcd tvs? Is it inevitabel? How often does this happen? Why does this happen? Will every lcd have dead pixels sooner or later? Sorry for all the questions but it just boggles my mind that i spent this kind of money on a tv and already have dead pixels. Any input would be appreciated, thanks.

Yes. Out of about 20 LCDs I've bought, maybe 1/3 have been perfect.

Manufacturing defects. It's too expensive and wasteful to produce 100% perfect displays.

I simply do not agree with the previous poster at all and I have the numbers to support it personally and professionally and I would expect him to post an objective white paper that supports his "Opinion" that it's as common as suggested - where is it? I own four LCD TV's and I have ZERO dead pixels! Three Sharps and one Sony. Someone was doing a poll recently and keep in mind it only lets you vote once when I have four TV's with zero I and others with multiple TV's only get one vote. As someone who spends my hobby connected to this forum for over three years virtually everyday I've seen no such pattern that reflects his numbers at all from fellow member postings during this time - it was much more common in the early days of LCD TV and Monitors. Common sense and knowing how this forum works if it were as common as suggested this forum would be littered with posts on this issue and it isn't and the poll would not have been pushed back to page 8.

65 Poll Respondents and the "Yes" is at 12.31% but again that doesn't account for some that have multiple panels since you can only vote once by the nature of the forum poll system. If I had four votes for four TV's without dead pixels and others then that figure naturally goes lower so keep that in mind. http://www.avsforum.com/avs-vb/showthread.php?t=981688

I also have over 400 LCD Monitors on my network and dead pixels are rare and half of those panels have been running 24/7 for five years with only one failure and none during the 3 yr warranty. They are the most trouble free IT Components on my network outside my Cisco routers/switches.

Sometimes monitors can get stuck pixels that often can be released by taking a microfiber cloth and your finger tip and massaging it and often the stuck pixels can go away. I've never had a stuck pixel on my TV's only on PC Monitors.

okay so i do have one dead pixel, massaging it out did nothing...i cant see it when i am watching tv, but up close i can and i know it there, and it does bother me...should i just deal with it? or should i exchange it for another tv in the hopes of having all the pixels?

If you can't see it at viewing distance, I'd leave it and just enjoy the set. The replacement could have 2, or 3, or 4, or ... The only time I'd worry about dead pixels is if they were noticeable under normal viewing. If the set is flawless otherwise, and you've got one defective pixel (out of around 2,000,000), I'd let it go.

I would be interested in seeing your industry-wide numbers on dead pixels.

My numbers are based on my experiences over the past 6-7 years and ~20 panels. I tend to buy high resolution panels, which have more dead pixels. And I also look for them, whereas most people are oblivious to them unless very obvious.

Most people don't even know their dead pixels are there. Stuck pixels are a little more obvious, but you'd be surprised how often people are oblivious to those too, particularly on a high resolution screen.

If everyone who bought an LCD combed over it with full red, green, blue, and white screens, you'd be seeing many more "dead pixel" posts.

As it stands now, only the obsessive types check for it and post about it.

Pretty much. There are programs like this that claim to be able to release stuck pixels by rotating the colors, but I can't vouch for them.

Most manufacturers/retailers will NOT let you exchange a set for just a stuck pixel (a "zero tolerance" stuck pixel policy). It has to be a certain number of pixels, or a smaller number that are grouped closely together. Each manufacturer's policy is different.

I was the one who started the poll about dead pixels that you can find here . I am not going to claim that this is 100% accurate as many factors could influence the outcome, such as people not noticing that they have a dead pixel when in fact they do, but 70% of people currently say they have no dead or stuck pixels.

Here are my 2 cents. If you have a 30 day return policy do it. You paid a lot of money for that TV it should be perfect. Dont listen to these people that tell say if its one just dont worry about it! Worry about it! Its ridiculous that you will pay that much money for a product that should be perfect. I had a tv that had dead pixels, the next had 0. So in my epxerience it is good to exchange for another. If you keep getting them, keep exchanging them. Its something you have invested in and should be happy with.

How many of them actually tested for dead pixels, though?

A dead subpixel, particularly on the edges, can be very tough to detect even with a computer monitor, where you're typically sitting very close and can resolve each pixel. On a typical TV where you're sitting far and can't see individual pixels, it's nearly impossible to tell.

Personally, I wouldn't bother returning a set just because it had a dead subpixel, unless it was right in the center. It's not worth the trouble and there's hardly a guarantee I'll get a better one in exchange.

Like I said in my previous post:

"I am not going to claim that this is 100% accurate as many factors could influence the outcome, such as people not noticing that they have a dead pixel when in fact they do"

However there are other factors that could contribute the other way, such as people with mulitple sets where only one has a dead pixel, or perhaps people who know they have dead pixels being attracted by the thread title including the words "dead pixel". It is hard to have a 100% accurate pole without a very large and controllable base.

My personal experience is that I noticed a single dead pixel while using my 32" LCD as a computer monitor from about 3' during normal usage and can easily see it from that distance. I can still see it from about 6' away during normal viewing although it is obviously not as noticeable.

well my dead pixel is right in the middle of the screen, and i do have a 30day warrenty,i to feel that with the money i paid for it, it should be perfect, so i will take your advice and return, and keep returning it until i get one i am happy with. thanks

No industry numbers here just real world experience. I'm an IT guy and buy many LCDs from 15's - 42's+. I recently went through 7, yes 7 Samsung 32" LCDs until I finally got one without a dead or stuck pixel. Some had more then 3 but most were one dark pixel that on lighter color screens were more than noticable. I couldn't believe it but the store was more then happy to keep letting me try until I found a good one.

It does seem very rare to get one on a laptop lately but about 1/3 of the computer LCDs I buy have some form of stuck or dead pixels. It seems the higher end brands are less likely to use cheaper panels so you have a better chance of not getting a bad one. I've never had a problem returning them for these reasons and I buy from many different vendors. If you get one with dead or stuck pixels and it bothers you I would return it. You are spending much money on something so you might as well get a flawless set. All companies list stuck, dead, or bright pixels as normal and will not after your return policy do anything for you unless they are usually in groups and/or spreading. This is very rare but I've seen it happen.

The "average joe" would be hard pressed to see them under normal viewing conditions. It's more the people with static images or sit close like a computer monitor. Sometimes ignorance is bliss in this case because once you find one your eyes will always migrate to that spot and you will always be looking for it. Anyhow my $.02.

well thank you for you 2cents, its appreciated, and i did end up taking that tv back to cc to get another once because theres just no way i will settle for that sort of money. but now i face another issue, when me and my gf opened the tv, it was all scratched, fingerprints on the side, no stickers like there were on my first one. so apparently cc sold me an open box without informing me, which is definetly illegal. someone gave me some really good input on what to do and how to go about it. so when i wake up i am going to go to cc and have a nice long talk with the manager. hopefully get some sort of compensation.

Take it back and show them what they gave you. I'm sure they will just replace it with another one. You may even want to check it out before you leave the store. The CC in my area has always been very good at making sure I'm satisfied, even going through their entire pile of boxes to pick out a certain serial number when needed.

Is it normal for a stuck pixel to start out displaying the correct colors and then slowly fade to a single "stuck" color?

My new Sony KDL52XBR4 looks perfect for the first 7 minutes after I turn it on, then one pixel near the bottom of the screen slowly fades to red. Is this normal for a stuck pixel, or is this something else entirely?

!!!NEW!!!LCD with DEAD PIXEL!!!NEW!!!

I bought a brand new LCD 46inch Sharp "LC46D92U".

After few days, i noticed that there is a dead pixel (green).

I was beginning to be worry...if it's normal. 1 week later, i noticed again that there is more dead pixels, 2 more (red and blue). Well welll...my LCD is still under the 30DAYS, so i can make an exchange or refund...should I???

I've ask to experts that knows a lot about LCD. Is it posible to find an LCD 46inch 1080p without any dead pixel???VERY RARE...NOT SURE...MAYBEE... The Liquid Crystal panel is a very high technology product with 6,220,800 thin film transistors, giving you fine picture details. Occasionally, or in my case PERMANENTLY a few non-active pixels may appear on the screen as a fixed point of blue, green or red.

Everybody, SHOULD I just go exchange it for another one or it will be much chances the same problem with others 46inch+ LCD(Sharp). Or just simply BAD LUCK with that LCD!!!

Yes yes I am very picky too...especially with some dead pixels on it...

Finally, I did exchange my SHARP LC46D92U...for an other one. Well just cannot imagine that it will be the same with MY 2nd one.

Can someone belive it or not... Here's with My 2nd SHARP LC46D92U with DEAD PIXEL AGAIN!!! Brand New in the box both of them...

My 1st SHARP was with 3 DEAD PIXELS (green, red, blue).

Now with My 2nd SHARP is with 1 DEAD PIXEL (blue), but this is just for the moment (maybee even more later).

The Liquid Crystal panel is a very high technology product with 6,220,800 thin film transistors, giving you fine picture details. Occasionally, or in my case PERMANENTLY a few non-active pixels may appear on the screen as a fixed point of blue, green or red.

Everybody, SHOULD I go EXCHANGE it AGAIN for the 3rd LC46D92U??? Simply BAD LUCK with both LCDs??? I want an 46inch 1080P LCD with ZERO DEAD PIXEL...Is this POSSIBLE???

I just purchased three 28 Inch LCD's. They were all perfect and I was very worried about dead pixels.

What causes dead pixels?
