Chosen Solution
I am getting 2 white color vertical bars approx 5 to 6 inches wide with 1 inch of black vertical bar in between them? I have unplugged the ribbon connected to the T-Con board and have cleaned it already from both the ends! what could be the possible solution of this? Update (12/20/2020) this is what I get on my screen
sandy woods could be a bad T-con board, bad main board and worst case scenario the panel. I would replace the T-con board first. Let us know what model your Samsung is so we can check on that a bit more.
