    Re: SHARP LC-40LE811E help

    Very strange, it looks like a bad panel for sure. There really are only three parts in a tv which could cause such a failure. The main board, the T-con board, and the screen. You have already eliminated the screen, so it must be one of the boards inside the set. Unfortunately I am not sure how you would determine which is which at this point.

      If you disconnect one of the tcon to panel cables do you have a clear half picture. Then reconnect the panel cable and repeat for the second cable.
      I think it's a mainboard problem.
      Willing to help but I'm no expert.

              Is the replacement LCD used or brand new? How much did you pay for that 'NEW' 40" LCD panel?
              T-CON cannot cause double pictures and horizontal lines.
