Cured my splotchy screen/ yellow tint

I had to return an iPad because of exposed back lights.

I bought another one at a local Walmart and received a splotchy pink and yellow screen. I decided to try something new to rapidly cure the glue that was not mentioned on this forum.

I set my iPad to 100 and wrapped it in a blanket. Carefully monitoring the temperature to make sure it did not overheat.

What I got after 4 hours is a crystal clear iPad screen. No more tint, and completely even color temperature.

You have to let it get hot.. Do this at your own peril... I claim no responsibility for damages.

This will probably not cure really yellow screens, just the splotchy dingy uneven tinted screens.

I'm curious to know if others with the same problem have had improvements with use or other techniques.

I set it to max brightness with a solid white image in photos.

When I was on the phone with the apple reps about my defective iPad the guy said they were having problems with the glue used to bond the digitizer to the screen.

I think many people have it confused about the glue situation, the screen is not bonded to the glass like I believe the iPhone is, but the digitizer still is.

He said the problem will go away with use, I can only apply a little logic to mean it will cure with use and with use there is heat.

Many people report that the warmest areas of the iPad clear up the soonest, so I just insulated the iPad so heat would not dissipate, therefor accelerating the curing process.

You have to be careful though, most glues will cure faster while in a warm environment, but if you superheat glue, they tend to soften, and degrade.

That is my theory, what I do know for a fact is I have no more dingy, yellow, or pink areas that I had before.

My iPad was made in Feb for what it is worth.

----------

In the yellowing thread, people are reporting a reduction in the unevenness on their launch iPad's with heavy use.

So in short my theory was to simulate extremely heavy use.

How did you exactly monitor the temperatures?
Common sense goes a long way. Electronics have an extremely high thresh hold for heat... They degrade with heat but they can tolerate it for a while.

I simply touched it every couple of minutes while I was watching movies.

Common sense does go a long way, Im glad I have more sense than you. Im assuming your skin has some kind of built in thermal sensor that you can safely say that the actual internals are not over heating, first you said you wrapped it around a blanket with a white screen and now its watching movies. What kind of sorcery is that?

Your assumption of "high tolerance for heat" is not in anyway related to common sense in how it was monitored.

Nice try though! ;)

wow people have pink on their screens how?!?
Unlucky/nitpicking people

REPOST AND UPDATE

Well, went to the apple store to compare..and the demo unit showed a blue tint compared to mine. I then asked for a replacement and they were very accommodating.

Opened first box....more yellow then mine.
Opened second box.....again more yellow then mine.

They wouldn't allow another one....and I completely understand....I was surprised and humbled they even allowed me to try. They could have said no. So I left with mine that I receive yesterday.

So that got me thinking that maybe some are right, and you have to wait a and see if the color changes on its own....since the demo units were most all blue, and maybe over the few days they changed, unlike the two box ones were yellow worse then mine and never got a chance yet.

FYI Mine was purchased online so the myth you can't replace it at the apple store...is just that...a myth.

Here is a pic I took today since mine was delivered yesterday. In a few days will take another pic....and so on....just to see if there is any change.

______________________________________________________________

Ok, here is status updates so far.

When I first got it, it was looking like Bergerfan's here. I left brightness all the way up with no turn off for the last maybe 38 hours.



3-17-12



3-18-12



3-20-12





Now some have argued it will change and others argued it won't. I am only interested in results and I will try all possibilities just to see for myself if they will work or not. If you copy the pics and flick through them you can clearly see the change.

So far my results have worked for me, you're results may very. Best of luck.

----------

Your a dumbass, I was watching movies on my TV.

Your an even larger DUMBASS because not only is your skin a "thermal sensor" but the iPad shuts down if it over heats, you could almost say that it has a "thermal sensor in it"

People on this board amaze me, I post a solution that worked for me, and then people like you want to know what my qualifications are to judge temperature, its called common sense, which you clearly lack.
Don't worry about it man....all you can hope for is that some will take what worked for you, and appreciate it. Some people would rather bash other peoples solutions, without offering a positive solution of their own.

Ok, all this is very confusing because I've seen screens with a yellowish tint, pinkish tint and something in between. When I checked the demo ipads at the local store I came across all three. Since the demo units have been running night and day since last Friday they should all revert to a more natural white if indeed it is simply a question of time but this was certainly not the case so what gives?

The demos at my store all have a natural white. There isn't a all to end all answer for everyone's screens. Just individual options for people to try.

Those pictures you took to track the "yellow" fading. How did you white balance them to ensure a consistent color temperature between photos?

If you just took them with your iPhone or point and shoot camera than they're completely unreliable for comparison. You have to lock the white balance and exposure between all the shots.

Then you need to make your stories clear and direct next time, "carefully" monitoring temperatures with your fingers does not fall into the category of "carefully" You were just looking at the screen trying to see if it got the over temperature warning and occasionally touch the back part, but the end of the day you were just dependent on thermal sensor on the device which you also admitted on your last post, I was wondering if you were using an IR-Thermal sensor in you "careful" monitoring. Im not even saying that the device will overheat or arguing that it is unsafe.

Theres nothing wrong with posting a solution that only works for you, the problem is why your so aggressive when asked how you monitored the temperatures, of course anyone can feel free to try this solution. You need to take a chill pill instead of obsessing on the yellow tint on your device, your starting to lack the ability to answer a very civil question proves that you need to get a life.

Good luck!

Could it be because of the store light? I took a friends Ipad2 to an apple reseller and can I definitely say that the lights they are using are making the Ipad2 give a very natural and bright white tones, at the same time I had another Ipad2 that also had neutral whites and they looked exactly the same with the store lighting conditions.

It could be possible that demo units are really cherry picked?

What I am hoping though is that these screen related issues get sorted out by the time I decide to purchase.

The camera was manually augmented and calibrated before I took them. The photos are correct. Thank you, for your suggestions though.

No, I have always been aware of terrible lighting in stores. I took that into account.
If its all natural white on the store then the demo units can be used as a basis to demand a product that is 'not faulty'

Yes, and this will allow for a return if one so chooses.....But I decided to help those who don't live near a store.....with seeing if said issue over time could possibly set over time.

What works for some may not be the best thing for others...that is why they have a choice......all I'm doing is posting my experiences to help. Whether they decide to take that help is their choice.

I was actually hoping that my friend's Ipad2 would still turn up yellow on the store light conditions so that It would have been easier for me to get an Ipad3, It will probably arrive in the Philippines late April, Till then Im keeping an open mind.

Yup...Hope you get a good one Earl.
