It’s not a dead pixel it’s a bright little spot. The colors still work normally but on a white background the spot appears especially bright and on a black background it’s a little subtle bright dot. (On a black background it appears like a greyish color.) It’s not a single pixel, it looks like about 3 pixels and it sort of fades, it’s not a sharp 3 pixel block that immediately stops it fades out over the course of about 3 pixels. It kind of looks like the backlight is super bright in that area for some reason.
I think it’s the pressure marks, something is pressing on the back panel of the LCD screen causing this kind of bright areas. It’s not dead pixels.
Is it easy to open the tablet and look under the screen?
Thanks.
