My TV was working perfectly fine then a minute later after shutting down a gaming system the colors on the TV changed completely. Even in apps, the colors of everything was blue, gray, and green. After restarting the TV the colors are back to normal, but the TV screen is flickering. The home screen will also be faded in the background of apps. I've been unsuccessful in trying things like unplugging it, factory reset, and checking cords. I've had this TV for a few years, but it's not old. Is there something I can do to fix the screen?
