Mine has been working fine for over a year. Nothing has changed, but all of a sudden, I’ve developed a flicker at the end of the light stream. It starts at the top left of the screen, and extends down the left side to the end of the string. I’ve reset the device several times, ensured everything is plugged in properly, and like I said, nothing has moved or changed in months. I added a 4K Apple TV a couple months ago, but that has been fine, until recently. The flickering occurs is all modes, and when in ambient mode, and a solid color, the colors of the issue area are off from the rest. If it’s blue everywhere, it’s pink there, or if it’s white, it’s blue. Any clue on how to fix it?
