Hi! I’ve been using my Casio keyboard for years now and in one incident, I just noticed a dark spot on its LCD screen. As seen on the photo, there is a cover underneath the panel and the dark spot is right on the LCD. When I turn off the keyboard, it’s still there. I am in question on how and why this happened. Any answers will be much appreciated. Thanks!
Black spots on LCDs are typically caused by either superficial dirt or debris, a stuck pixel or a dead pixel. The easiest problem to fix, of course, is a superficial dirt or debris. In comparison, stuck pixels are a little harder to fix, whereas dead pixels are the hardest to fix. If a stuck pixel is creating a black spot on your LCD, you may be able to use a third-party flashing tool to restore it.
