Television and Home Theater

Has picture but no sound

My LCD tv has recently starte displaying a leading ghost on all images (usually black against a gray background shows it best. Likewise, on many images especially on female face's, there is a very annoying red outline to the left of the leading edge of the face. It occurs on ALL inputs including a NTSC test generator connected to any input. I suspected a thermal pproblem, but that does not seem to be the problem. Likewise, a black line against a yellow image shows this red problem.

I have forgotton the 4 digit code for my SHARP Tv please help is there any way i can reset it?
