Backlight bleed is a common issue in LED TVs, but it is not necessarily normal. While some degree of backlight bleed is expected and can be a byproduct of the manufacturing process, on the LG 55” Class UA77 Series LED AI 4K UHD Smart webOS TV (2025), Model# 55UA7700PUB, it can also be caused by factors such as temperature changes, overtightened screws, or manufacturing. If you notice significant backlight bleed on the TV, it may be worth contacting our Customer Support on social media (Twitter, Facebook, instagram, YouTube etc.,) using our handle @LGUSSUPPORT for a warranty service, or to discuss potential repair options...^Ivan. 6
