Pixel "stains" of different color on top part of the screen
Hi all, yesterday I noticed that the upper part of my tv started to have some “stains” of pixels showing colors different than what they are supposed to be.
Normally these stains are of a light blue color when on the screen there is a bright image, then they turn black if there is a completely red background and when there is a black image they are completely unnoticeable.
I also noticed that if I look closely with a flashlight these stains sort of remain even when the tv is turned off.
I never spilled water on it or anything, actually i never even moved the tv in 4 years.
Any idea what it could be? (TV model: Samsung UE55JU6400)
Is dit een goede vraag?
