Don't make this mistake when buying a new TV
If you buy a new TV, there's one mistake you should never make. Some new models come without their protective film, which often fools people. Because of this, some mistakenly peel off the polarizing film, and when they do, the screen turns completely white. This film is key for controlling brightness and contrast; without it, the screen is practically useless. Interestingly, if you put that film in front of your eyes, you'll see the image while everyone else just sees a white screen.
