here i have a tv that had no display. sound was present, backlights were present, but no actual video. I started out taking everything apart. My first instinct was to go to the tcon. I Unplugged one ribbon one by one, and finally i got half the screen to be on.
I replaced the tcon because usually those go bad with those symptoms. One thing you could do to make sure the tcon is good, is to measure the inline fuse. It should be be 0 resistance.
It turned out that it was the lcd that was bad. Unfortunately it will be a lost TV that will be parted. Overall This is what I usually do if I get these symptoms.
