I have a 65" Samsung that developed RGB single pixel lines on left side of tv, I took apart and reseated all the ribbon cables on that side with no affect. Is this the panel? I only see a main board and power supply, no tcon board so things have changed since last time I worked on one. Is this trash?
Were you able to resolve this? My tu7000 is 1 month past warranty and developed a vertical line on the left side yesterday. It's on all inputs so it's not a connection. Plus I stream TV so no HDMI inputs are used.
