    Can you post a pic of the t-con board? There's normally a fuse close to the LVDS cable connector. It's usually labeled as "FX" or "FPX", where X is a number.

        The device slightly above "F1" marked "UD".

            Yes; or the panel is. Remove the LCD panel connectors (opposite the LVDS cable on the T-con board) to rule out a panel short. Panel shorts are very unlikely, but in rare instances can cause this fault.

                  Well, it depends on your soldering skills, if the board is cheap, I would just replace it. But first, you can check the little beige MLCC:


                  for shorts. If you find any shorted, you might be able to temporarily remove them and power the set up (it should work but may have picture distortion or noise) at which point you can replace the cap with a new one.
