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.
