How many dead pixels are too many dead pixels?

Hi all:

I started noticing white spots in my Powerbook G4 1.5ghz 15inches about 8 months ago. Took it to the apple store in Glendale, California, and the guys, after debating for a while, told me that 3 dead pixels were not enough for apple to replace the display.
Last week, after noticing about 7 white spots on my screen, went back to the store, showed it to the guys and they said that they were not dead pixels but white spots (I new that much) that they were not sure if Apple would replace the display but they asked me to send it in. They also said it may cost me $1400 to replace it.
Well, they called me today, told me it was ready to pickup. When I arrived at the store I booted it and was happy to notice that they had replaced the display at no extra charge!!!

I have a iMac Intel 20". I've now got a full vertical line (top to bottom, 1050 pixels) red and sometimes green line. It came and went a few times over a few days but now it seems quite permanent.

Bought the imac have a year a go when the intel was fresh. Haven't taken it to an Apple shop yet. I live in a different country than I bought it, but that shouldn't be a problem as warranties are international.

They should replace the screen. I expect not that get any difficulties, as it's basically 1050 dead pixels...

Bright Up to 3
Dark Up to 5
Combination Up to 7

that's for an MBPro

I used to do warranty work on LCD's, not for apple though. Some companys actually use a percentage if X percent of pixels are dead then replace. Most companies just use their best judgement. If more than 2 dead pixels were in close proximity(1 inch or so, we would generaly replace. If it took longer than 1 minute to find, generally wasn't replaced

I definitely had one dead pixel on arrival with my powerbook and they replaced it. It also has a speaker malfunction, the right one would rattle...but that's off topic. Both are fixed and that is that.

I bought a dual 2.0 G5 and a giant 20" cinema display in august of 2004 right before the brushed aluminum designed monitors rolled out. I had a bright blue dead pixel staring at my face since day one. I'm a film and video student and the pixel is RIGHT where I don't want it, in the top right side where the final output video (canvas) goes by default.
I went to the apple store in grand rapids, michigan... they said "bring it it" but no gaurantees. they hinted that simply 1, no matter how annoying it is, will not be covered under applecare. sad.

I had dead pixels (apx. 8 pixels) and a faint white spot (1 inch in diameter) in the center of my 15" powerbook screen. The Apple store on North Michigan Ave (Chicago, IL) wouldn't replace my screen. However, a week later at the store at Southpointe Mall (Durham, NC) they immediately took it in and replaced it for me. Seems like it definitely is entirely subjective...just find a nice "Genius" and you've got yourself a new screen!

PB 12" + Cinema 20" - not one single dead pixel. Or: I don't know anyone in person who got an Apple product with a dead pixel. Maybe because there's a european regulation, forcing to classify products into different "dead pixel classes". Anyone knows more about this?

My old iMac G4 got a column of stuck pixels about 6 months ago. Leaving it on with a screen saver, flashing random colors at 30fps, did nothing. Do you guys think I should see if Apple will replace it?

Consider that there are 3,888,000 (1440*900*3) individual sub-pixel elements on a MacBook Pro's screen. One of them gets stuck on resulting in a bad pixel. One out of nearly Four Million. People should think about these things before screaming at their local Apple Store employees and becoming "that customer" who ruined their profits for the month and hurt whatever incentives or bonuses the employees might have enjoyed.
