If you have 12V on both sides of the fuse to the tcon, then the tcon is suspect and time to order a new one.

Show us good clear pictures of the backside of the TV showing all the boards so we can see what we are dealing with.

@larry708 I had the same issue where I did not get a picture on either side after unplugging the ribbons from the T-Con to the panel. Replacing the T-Con fixed it. But it wasn't guaranteed because there was a few times on other sets did not fixed it. But you won't know without replacing the T-Con.
