Hi all, I tried searching the site for answers but I'm a bit over my head understanding some of what might apply and what doesn't, so please be patient with me.

Hi all Happy Holidays! Was just wondering if you think this white vertical bar would be fixable. Maybe bad TCon or ribbon cable? Contemplating trading a 50 inch Hisense 4K Roku for the Samsung but might get burned lol. The Samsung is model QN65Q80AAFXZC QLED TV has a white vertical Bar. Any thought appreciated. Thanks.
