    Thanks for the follow-up on the repair, good clear pictures help a lot in troubleshooting down to component level and it only takes 19 posts to solve the problem. Nice 65" TV!

      I spoke too soon!

      The backlight is fine but now there is another problem. When I turned it on this morning I saw this screen with colored bars again.

      This happened the other day but I reseated the two ribbon cables to the Tcon board and then it worked.

      When it was working, I also noticed some ghosting (afterimage of a news logo remaining on screen after I changed stations) on the right side, and if the scene changed rapidly, it would look like it smeared.

      And the center of the screen was a little darker than the rest.

      I'm at a loss right now. Is it the panel itself? Tcon board? Ribbon cables?

        Check those ribbon cables again, you can clean them with a pencil eraser.

          I swapped the cables and the problem still exists on the right side. I'm going to make a new thread since the backlight problem has been resolved.
