A:Answer Hi Tabitha. We regret to read about the issues that you are experiencing with your LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UH6150 and apologize for any inconveniences. The issue that you are describing is a black uniformity issue, also referred to as Clouding or Flashlighting, which can be only seen during dark scenes and only when the TV is being watched in a dark room. The diffuser layers and the LCD screen for the TV are somewhat flexible and a slight difference in pressure on the frame of the TV can change the uniformity on the TV. On some TVs it can be fixed if it is caused by an issue with the frame's pressure. For clouding, a simple fix will be to power on the TV and display a black image. This will allow you to see the lighter spots on the screen. Next, take a soft cloth and massage those brighter spots to improve the uniformity. You should only apply very gentle pressure, just barely touching the screen. You can also try a few different stroking patterns. If you are patient enough, this often works surprisingly well, especially on edge-lit TVs. Some models are more prone than others to having issues. Even within the same model, some units can have more of this issue, because of a slight variance in the manufacturing or the shipping process and you can always see about exchanging it for the same model...^IFV
