I have an LG 4K 43" TV that has provided great service. I bought this TV second-hand from a colleague and have been using it for about a year. Everything on the TV is fine, except for a thin white horizontal line visible across the middle of the display. Other than that, everything is perfect. The line is not visible while watching movies; it is only noticeable on a white screen. I have been using it this way for about 3 months without any issues. Those who are interested, please contact me. I have attached a photo showing the display issue, please take a look.
