Bottom quarter of the screen is discoloured
I just noticed that the bottom quarter (approximating) of my screen (when held in landscape mode, home button on the right) is discoloured. It isn’t usually visible, but grey is rendered as a green and other colours sometimes blue. Right now, it doesn't affect usability, but it is annoying. I assume that I would also be able to see red with some experimentation.
The iPad is brand new and it’s the 256 GB model, so it’s quite expensive. Under Australian law I could get a free repair or replacement (I’ve only had the device a month and it’s malfunctionaing), but I’d rather fix it myself, and without taking it apart. I haven’t dropped the device or submitted it to any more weight than an iPad 4, and it has a Targus case on it at all times.
An IT manager I used to work with had a remedy he used, where he flipped the iPad over and hit it with the palm of his hand, just beneath the Apple logo (this was with multiple iPad 2’s). He described it as the backlight being out of place. Would something similar to this work? If not, are there any other solutions that don’t require me to open the device? Thanks.
