How do I fix iPad2 screen colors all messed up?

Try this Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost).

I just had this exact same issue. The above did not work. Restoring did not work. What worked? Giving the iPad three gentle-ish taps on the back! I had to do it a couple of times, but it's back to normal now.

This happened to me twice so I'm all ready to help :). Start my going to Settings>General>Reset>All settings>confirm then let it reset the with a hammer on the side by the speakers, home button and plugin outlet tap it hard not so hard only hard enough so it won't crack. The colour will change to normal then it will go the same colour if it does hit it again like u did the first time. :) I hope I helped at least someone. It worked for me! Good Luck! :) like if it did

So... I did restart with the home button and allthat jazz.... But, what this geniuses did not understand, is thts the question, it was a physical problem, not a question for in software adjustment! Hitting it in the back and in the sides worked, with your hands, DO NOT ISE A HAMMER. IT IS NOT REQUIRED, SIMPLE TAPS ON THE BACK WILL DO!

Gently knocking on the table worked...I work with around 1000 iPads at a middle school...the kids think we are geniuses! Of course we don't let them see our trick...we don't want them banging them around more than they already do!

I was having color issues as well so I tried the 3 slaps on the back cure .This is no joke ....IT WORKED for me !

I just went into my wife's room, asked her for her ipad, (with cover,) whacked it three times on the back, and handed it back to her, fixed. (For now.) 🙂 I also told her I was a genius. Thank you!

Oh my goodness! The tapping it three times is like magic! Thank you WoolyMittens! You're a lifesaver!!!

the 3 slaps on the back worked for my iPad 2, first time the screen went black, then i kept trying until all the colors back to normal, thank you for the great idea.
