LCD bad pixels turning good? possible??

[Nestle]

I just received a Planar LCD and i noticed it has some (6-7) bad pixels. Some of them are red some green some blue and some white. (They are visible only in dark backround)

I called Planar and they said that i should leave the monitor on for 72 hours, and that if after this i still had more than 5 dead pixels they would replace it.
Has anybody heard of bad pixels turning good after some time? I never heard of such thing. Is it posible, or they are just wasting my time hoping that after using it for 3 days i will get used to the bad pixels and i will not bother to return it?

 

[Adul]

maybe it is the brun period hehe. otherwise no.

AFAIK it's standard fare to have you leave it on for 72 hrs with the brightness cranked all the way up.

I'm sure there's a reason for it, though I've never owned an LCD myself.

Well, I hope ( although i doubt) that the bad pixels will go away.
Also I hope that if i send this one back, they will not just send me one that still has bad pixels bad bellow the replacement limit.

How many of the people that use LCDs have bad pixels on their monitors? Is this very usual, or I was unlucky?

 

[Gunbuster]

My Planar had 2 (stuck sub pixels), I exchanged it with dell for a perfect one

And no they did not go away after 72h, I doubt the chances of 6 healing is very good

I had a couple of red pixels on my LCD. I have returned it to the place of purchase and I am waiting to hear from them. I think it's unacceptable to sell a defective product and refuse to replace it because it isn't 'defective enough' (something they hinted at doing).

agreed.... although, relaly old hard drives came with a sticker saying which sectors were defective so you would know not to put data there (modern HDs hide the bad parts)

It's very, very possible (And probably) that the pixels will straighten themselves out. I wouldn't count on the white one coming back, and likewise if you have any black ones, but the red, green, pink, blue, etc ones should.

Even though you can damage your hardware doing it, gently massaging the screen WILL fix them (but DON'T do this). The reason this works is a combo of the applied heat and pressure unsticks the pixel. I'm guessing leaving it on would cause some sort of heat behind the screen, maybe unsticking it.

Either way, I've got a toshiba lappy that has had stuck pixels, and they've all gone away, so good luck!

Now there are 7 stack pixels. The worst thing that can happen is if some of them become ok, so they will drop the number of bad pixels bellow 5, in which case Planar will not replace the monitor and I will have to deal with ecost (and they usually charge 15% restocking fee, which means I will have to fight with them for it).

rub your finger over the pixels and see if you can get them right

 

[stonecold3169]

I just noticed that you just got the monitor... try massaging them out... if you happen to kill other pixels in the process, too bad... if you fix them, great, else try and get a replacement

 

[Nestle]

I try massaging it, but it didn't work. Now about a day past and nothing changed.

Will planar pay for shiiping of the defective monitor back to them, or i will have to pay for that?

Heh heh, not both way's buddy.

 

[Adul]

you pay for shipping to them

Actually, a screen with no bad pixels at all is rated as a "Class 1" screen... all the manufacturers agree that it is impossible to reliably manufacture LCD's to this tolerance today. That is why they have various numbers of pixels that must be bad before they will replace the display.

Although I completely understand your un-happiness, it's a risk of buying an LCD screen... that's why I would never buy one from someone who didn't have a good return policy!

If you want more information about the bad pixel thing, and manufacturing limitations, refer to this doc.

With Planar you do NOT pay shipping

 

[Nestle]

I called Planar again and they are now sending me a new monitor. They will also pay for the shipping of the defective monitor back to them, so thats good.
I asked the lady about bad pixels, telling her that i hope that the new monitor will have non of them, and she said that there is a posibily to have 1 or 2 again. I hope that will not be the case because it really ruins an otherwise perfect monitor.

You know, I just bought a Dell 2000FP and there are 0 bad pixels (that I've noticed in the three days that I've had it, and I'm usually very attentative to such things). Others who have bought this monitor have also remarked that they haven't seen any bad pixels either.

Pretty darn good for a screen of such size!

 

[RalfHutter]

I just got a Dell 1900FP (it's the Samsung 191T) and it has zero bad pixels. It's the fifth LCD I've owned and the first one with no bad pixels. Keeping my fingers crossed!

So bad pixels can appear later on?

 

[Czar]

I read somewhere that if you rub the pixels the right way they go away

not kidding btw

Yes, I've had several LCDs that have had pixels go bad on them after awhile. The screens were never dropped or bumped, they just went bad.

Like I said, "keeping my fingers crossed" on this one. It's cool to get a $1000 19" LCD with NO bad pixels, I just hope it stays this way.

Was thinking of getting the same monitor. How well does it handle games?, it claims 25ms response, so should be reasonable.

I think this really sucks. The monitor I got was really great, but even ONE bad pixel is totally unacceptable and it destroys everything positive. If i knew that bad pixels were such a huge problem I wouldn't invest $1000 for an LCD. With that money I could buy an excellent 21" CRT that would last for years without any problems.

I just hope the one that will sent me now will have no bad pixels and it will stay like that for at least 2 years.

If it again has bad pixels, do you think it would be posible to return it and ask for a refund?

Manufacturers make it pretty clear what the expectations are for LCD's. Anyone buying an LCD panel needs to understand the state of the technology and that bad pixels are a possibility.

Maybe someday they will be able to manufacture panels with 100% guarentee of no bad pixels but that is not possible today.

One way of looking at it is that your typical 17"-18" panel running 1280X1024 has a total of 3,932,160 pixels (red green and blue pixels for each point on screen). One bad pixel is pretty good actually.
