The iPhone has a free app for that, *checking for an iPad version*

Update: No app so i went ahead and visited the site and did the check. No pixel issues or yellow tint :)

If you have a dead pixel should it show up on every color including black? I can't tell if I have dead pixels or just dust/dirt under the screen. I have cleaned the screen but I have 2 spots around the middle of the display. If I look at them from an angle it looks like they are on the glass, but that could just be my eyes playing tricks on me.

I have a piece of dust under the glass. It's pretty large and can be seen even if the screen is off. Just my luck haha.

I called apple today and complained about the issue I have. The guy I spoke with is going to get back with me tmr about verifying stock at a local apple store and setting me up with an appt to get it replaced. Since the store is over an hour away it sounds like they will be giving me some accessories for my trouble. Will have to see what they say for certain tmr.

Any update on your issue? I found a spec of dust in my glass as well. It is very tiny but now that I know it is there my eyes always wander to it. I wanted to see if it was even worth trying to exchange for a new one.

Update

I took my iPad to the Apple Store in Manhattan Beach today. The gentleman that helped me took a look at the display, listened to my concerns, then took my iPad to the back (he first asked me if I had my data backed up)

He returned 5 minutes later and said they were giving me a new iPad because of the foreign object seemingly beneath the glass.

It was a very pleasant experience.

Not sure if I have a dead pixel or dust under the screen. Not sure I'd want to know. Looks fine with the naked eye, I'm fine with that.

Fairly early on I've noticed one dead pixel on the bottom left corner of my screen. I saw it when a black screen came on in that area. It's good to know that Apple will be more than happy to replace the product due to this issue. I'm in no rush but I will be bringing this iPad back for a new non defect one.

This app for the iPhone to check the LCD screen for bad pixels is NOT available. WTF?
You don't need and app for that. Just download the solid color pictures and use that to find any pixels that stand out. For me it was a white pin dot that showed up when full black color is displayed.

I agree solid pictures will do the same thing. Black or white are the best for this purpose. Black will show any stuck pixels while white will show any dead pixels.

A white dot is a stuck pixel, not a dead pixel.

Dead pixels will always be black since they can not be energized. Stuck pixels will be white, red, blue or green. Usually stuck pixels will go away just as they may appear over time. It is common with this type of technology.

Personally, I've have not been concerned since I'm fine with the technology. Additionally, I am not using it for photo editing like my laptop is used for.

Thanks for the clarification.

Is there any way to unstick the pixel?

You'll see different opinions about this.

Some say it will unstick by itself over time. Others say that if you run a video/movie with bright fast moving scenes (Cars and Speed Racer have always been good recommendations in the Home Theater Forums I visit).

I am in the camp that a movie will fix it. I feel that you need to use it to fix it.

I do have a computer monitor with a blue stuck pixel, but I have never tried to fix it. It has been there about a year, but the monitor has probably been used a total of four hours in the past year. It is not a primary monitor. Also, it was not there when I first purchased it. It appeared about a year and a half after purchasing it.

I hate this stuff. If you have to test it to see if you have any problems then you don't have any problems. I can promise you that many units that are returned for "defects" would be "perfect" in the hands of many. A cluster of red stuck pixels in center screen would be problematic. One or two spread around that you only noticed by running a "test" that does not reflect everyday use is not really an issue IMHO.

The one I knew about wasn't much of a problem, but I'm still debating if I should seek a replacement

My method is to simply look at the screen. If I can't see it without loading up a fullscreen image of a single colour it doesn't bother me in the slightest.
