So you mean the display screen by LCD... a66 is using an AMOLED (active matrix organic light-emitting diode) display, not an LCD (liquid crystal display).
Did you manage to find one. I think I need to change my a66 screen. it seems to flicker badly in the mornings when the phone is cold .
Same problem here.But it's worse now.It wont stop flickerin.Only goes lower when it gets warm. Didn't think that it would be impossible to order a new screen.
