Did some customers of the new Ti DVI 667/800 experienced the "some pixels down" frequently described with the first machines. I want to upgrade my perfect 667 to a 800 and should be disppointed if this new screen is not perfect.

Karim · May 8, 2002, 11:07 AM

My screen was perfect. No pixels out in any colors. No pixels stuck on in any colors. (PBG4/800)

Are you talking about dead pixels or something else?

Yes, Italk about dead pixels... It was a problem often seen on the first Ti
You can see the article in the knowlegdge base :
LCD Displays: About Pixel Anomalies (ID 22194)
It's explained as "normal" because : "Rejecting all but perfect LCD panels would significantly increase the retail price for products".

My 800 is just arriving I opened and the screen seems perfect...

Todd Corzett · May 10, 2002, 05:07 AM

I just got my Ti800 todaY, and unfortunately there is one stuck/dead pixel. Well it's stuck on red, but only when there is something dark where it is. When there is something bright/white it is totally normal. Weird, but It's not too big of a deal. It is too bad that after spending so much money on the laptop there is a messed up pixel - but like it was said - throwing away an entire LCD would cause even higher costs.

Dead pixels are a fact of life with LCD panels, and only time will improve manufacturing techniques far enough to eliminate them.

Never mind that dead pixels are completely out of Apple's control: Apple doesn't make LCDs.

Good point tooki. Luckily it seems like there have been very few complaints on the new powerbooks on this one, but time will tell. The higher resolution also helps, since if the pixel is stuck at least it's smaller!

Mine seems perfect, I did a quick run-through with a pixel checking program, but I didn't want to look too hard!

TheTraveller · May 13, 2002, 05:35 PM

The screen on my TiBook 800 is perfect.

seanyepez · May 13, 2002, 10:57 PM

All my PowerBooks have had perfect screens. However, my two new iMacs have a single dead pixel each.

MadMacs · 02:05 AM

PeteWK · May 13, 2002, 11:53 PM

My new G4 667 has a flawless screen. This is my 7th Apple laptop and the only one I've ever owned that had any bad pixels was a 1400cs that developed two after almost three years.

Apfhex · May 14, 2002, 01:34 AM

No deal pixels on my new 800MHz model. The screen looks great.

There's a dead pixel on my 19" CRT though

jwtseng · May 14, 2002, 01:59 PM

I consider myself lucky after reading on these forums about dead pixels and massaging them and so forth, but I have *never* experienced any problems with dead pixels starting with my first portable, a 180c. I've also owned a Duo 2300c,5300, 5300cs, 1400cs, 520cs, 2400c, iBook 600, all revs of Ti. Not a single dead pixel on *any* af these machines.

Snubben · May 14, 2002, 03:27 PM

Is there a program that helps in identifying dead pixels?

I have this same problem on a first-gen 667. Will Apple fix this or do there have to be more dead pixels? It's no big deal, just kinda annoying now that I noticed it :-)

iChristopher · May 14, 2002, 11:03 PM

I have the exact same problem on my 17" Apple LCD. Just one red pixel that only shows up on very dark backgrounds.

One dead pixel on my new Ti DVI 667

rek · May 16, 2002, 02:19 AM

My new Ti667 has one dead pixel, and one blue subpixel that seems to be a bit brighter that it should (i.e. faint blue on a black BG, brightish blue on a faint blue BG.) But, they're near the edges of the screen, and I can only see them if I actively look for them.

I guess this is the world getting back at me for every single laptop I've ever had before having perfect LCD screens ...

Judge_Fire · May 16, 2002, 06:40 PM

At your own risk, you can gently rub, or massage, the dead/stuck pixels and perhaps bring them back to a shiny happy multicolored state. Did it once, it worked for me. There are horror stories out there, too.

Search Google with 'rub dead pixels' for more details, before trying it out - easy does it.

M�lum · May 17, 2002, 05:42 AM

I just got my new Ti 800. For the first time after 5 generations of Powerbooks and one Cinema Display, I have a dead pixel....
But who cares! The screen is so much nicer for the eye then the Ti 500.

jules · May 21, 2002, 09:01 PM

Just got my 667 DVI and there is one (I think; it seems very big) big fat green stuck pixel almost in the middle.
This is very depressing... I have had 2 dual USB iBooks, a Pismo and a Ti 400, all with perfect screens.
I have been massaging it like crazy, with no luck....

Have that problem on my cinema display

Todd Corzett · May 21, 2002, 10:41 PM

If you would like me to take that cinema display off your hands I think I could manage

Then I'd have a matching set of stuck pixels... not to mention a new display

On a more serious note, I've found that I can hide it for most uses. I currently use a red background picture anyhow, so it's not visible unless I open up a movie or something. It gets a little annoying, but I just try to live with it.

-Todd...

note: I would have still purchased this computer even if I'd known about the stuck pixel. It really isn't noticeable for everyday things, and the computer more than makes up for it... IMO

rek · May 22, 2002, 10:14 AM

Would you know it, but one of the dead pixels on my screen somehow got worse -- on the adjacent row of pixels, a weird white line/streak formed (intense bright white on the edge, and slowly fading to the "normal" picture.) It wasn't a dead "row" of pixels, it was like half a row of pixels stuck on white, with the fault fading away.

Took it to my Apple Centre this morning, and they sourced and gave me a new TiBook replacement a few hours later. And no dead pixels on this one! Yay!

Then again, the dead pixels on my other screen never really annoyed me anyway ..

That would REALLY piss me off! Pay twice as much for a monitor as most people pay for a whole computer and it's not perfect! I don't know what I'd do but it wouldn't be pretty!

richf · May 24, 2002, 12:52 AM

I had a bright blue stuck pixel on my Ti800; massaging didn't work but I tapped the back of the screen behind it and it vanished. I was amazed (and quite pleased.)

You don't even want to hear what is wrong with my dp800.

BTW: Did I tell you i actually had to send my original cinema display in twice? the second time it came back it was broken (the right leg was smashed). Unbelievably the first apple rep (customer support) denied their responsibility and kept stating they wouldn't cover it, finally called customer relatiions and got it replaced by one that came in a box that was kicked (sigh)

oh well. At least now I only have one big red dead pixel and about 3 green ones if you look for them (They're not easily visible).

And here's one more thing for those who are considering purchasing a cinema display.. Mine is getting worse by the day, the edges are getting yellower and yellower.

I'm really dissapointed, we paid 7200 for this setup, a few more bucks for the rest of it, and it seems to be no better than if I went and got a dell for about 1/7 the price

SillyMe · May 24, 2002, 07:21 PM

Unrelated, yet funny:

My friend bought a new Kodak top of the line (at the time) digital camera this February. He got a great deal, like $150 off MSRP WITH the docking station.

Anyway, to make a long story short, on the 1.5 inch LCD, there were five, yes count em, FIVE (5) dead pixels!

It was so hideous we both started laughing hysterically (we both own Powerbooks with no dead pixels). Oh well, for those of you that have 15" "megawide" displays with one dead pixel, it could be worse.

FYI, all the Kodak cameras we have bought have no dead pixels.

Gater · Jun 8, 2002, 12:07 AM

I just purchased a new TiBook 800. I have one pixel on the far left of the screen stuck red

It doesn't show up most of the time, unless the screen is dark. I have also noticed that the screen is slightly brighter at the bottom edge of the screen. Is this normal?

PJ

Yose · Jun 8, 2002, 04:26 AM

No dead pixels on this Ti 667 DVI.

However, I do have an 'aura' of white along the bottom of my screen, it's just off center to the right.. and at either corner of the screens bottom it gets dark -- no big deal to me, unless anyone here knows that it is the symptom of a bigger problem

Also, the bottom shell is seperating from the rest of the machine on the bottom side just by the edge of the slot loading drive. Hrm

All in all, Im very impressed!

If you don't count the inconsistancy of the keyboard depending on where on the keyboard you are typing (on the sides it feels rough and forced, in the center it feels heavenly).

Ohwell!

I am happy, nothing in this world is perfect and if my GF can put up with all my flaws I can put up with the flaws of this machine.

Adios.

Buckaroo · Jun 8, 2002, 07:45 AM

No dead or stuck pixels on my new PB G4 800.

This is my 5th PowerBook with no dead or stuck pixels.

It was a concern this time, so I drove to CompUSA and bought it where they have a 14 day money back gaurantee.

mrwalker · Jun 8, 2002, 08:34 AM

I have one pixel stuck on green in the bottom right hand corner.

I've given it a rub but nothing happened. It's not too distracting an dI suppose I need something to keep this fella from being 'perfect'; I'd rather have a faulty pixel than any other kind of silly problem - lid not sutting properly, faulty ports etc.

euphras · Jun 8, 2002, 01:27 PM

Also no dead/stuck pixels on my new 667 "Ivory", Like others i observed that the bottom edges are faintly brighter than the rest. I think it�s due to the tension of the casing that�s build up by the hinge arms. If you press the back in this area it gets darker...

I have also noticed a small spot on my TiBook 800 screen that is lighter than the rest. It looks kind if like there is a drop of water on the screen. Very small, but several pixels are affected. It shows up the most when the screen is white. Anyone have this prob?

I have the same problem, the bottom of my screen is so so lighter, i think that it does not let me work fine. Also, the top of the screen is darker... Is it covered by the warranty? Is it a simptom of something worst?

My Ti 800 is gorgeous. The LCD screen is incredible!
No dead pixels, very sharp, very bright picture. It is the best laptop I have ever worked on.

A happy Ti owner!

�ig� · Jun 15, 2002, 02:10 AM

I have one blue pixel on my Pismo. But the real problem is the poor backlighting. Hopefully the new TiBooks ain't got this...

Buckaroo · Jun 15, 2002, 11:50 AM

Well, for 13 days my screen was perfect. Yesterday, I noticed one dead black pixel one inch in from the left side. I say one dead black pixel because it shows up blue when the screen is black. I ran the Pixel Check program and that is the only problem. Today is the last day that I can bring it back to CompUSA for a swap. Everything else is perfect, and the dot is so small.

I tried rubbing it and that dosen't help.

How did you tape yours? Did you take the screen apart? I don't know if I want to risk causing $1000 damage to blank out one pixel.

It dosen't show up in any other color. Just blue dot instead of black.

Oh, you tapped it. Maybe that is why I never noticed the dead pixel before. My eyesite is getting bad.

<blockquote>quote:<hr />Some of you guys are saying stuck pixels are just a fact of life and can't be controlled by Apple...<hr /></blockquote>Bull. Apple has a QA program that should detect these problems. We know that Apple doesn't make all the components in the PowerBook, but to say they shouldn't be responsible because someone else made a part that they later packaged and sold is like saying it's OK if the wing falls off your Boeing because the rivets were purchased from a sub. Fact of the matter is Apple (and Boeing) act as the "general contractor" and is responsible that the end result meets the spec.

I've been fortunate with both a Powerbook and a 22" ACD - no stuck pixels. But you can damn well believe I would have returned them if there were stuck pixels - policy or no. That's what credit cards and cardmember protection is all about.

fwiw

Yose · Jun 16, 2002, 01:22 AM

I am sitting here at work (Charity fundraising tonight) and I just came off the floor to find I now have a PIXEL ANOMOLY. There is an ALL WHITE pixel above my dock in the lower right quadrant of my display. The white pixel is brighter than the others and seems to be only visible when the screen is displaying white or light images.

Perhaps it wil go away, maybe I will try rubbing it out.. who know! But Ill definatly post the result.

Buckaroo · Jun 16, 2002, 10:53 AM

This is crazy. As mysteriously as my dead pixel appeared 2 days ago, it has disappeared.

Over the last 2 days, I rubbed it and tapped the back with no luck. This morning I turned it on, and it was gone. The dead pixel is no longer dead.

The yield (perfect pixels) from LCD manufacturing is so low, that Apple would have to discard a huge amount of panels because a such a large proportion will have at least one dead pixel, whether the OEM is Sharp, Samsung, or whomever. It's just the process. There's like a million of these pixels, and its hard to make every one work on every panel. You cannot fix a dead pixel - you toss the whole display. They would have trash bins full of LCDs every day, and the cost of this would have to be passed on to YOU.

Did you know this also happens with chips? A big percentage get tossed because they fail tests. It's an accepted fact of the industry. If you could figure out a way to make the yield 100%, you'd be very rich indeed. But, you can't pass off a broken CPU like a dead pixel.

We can only hope that the manufacturing process will improve.

I agree that staring at a pinhole in a brand new screen sucks, though...
