Sharp aquas LC-46E77UN horizontal lines

[E-rock]

Hello,

I have I have a sharp aquas LC-46E77UN that has faint black horizontal lines over the entire screen.
They are on all inputs and menu screens.
They are not visible on a plain white screen.
They do not change in size when screen size is changed.

Does this mean the panel is bad?
Any thoughts would be appreciated.

It's probably not a panel fault, but then again this is a common problem on some Samsung TVs, so far no resolution with T-con & main board replaced. T-con would be my first guess, but it's a rather hard one to decide on.

Thanks for the reply Tom!

I was hoping to narrow it down a bit as the main board is costly lol.

I have heard its the display if when changing ratio that the line sizes don't change?

Also heard that if the lines are not on a white screen that it is not the display.

These thin black lines ( actually two thin lines very close together) are so even and over the whole screen with no other issues seams strange, on people's faces and such they are not visible.

I reset the cables to t-con with no change.
Also did not see any bad looking caps on the mother board.
I have seen the Samsung displays with similar lines but they are quite different in appearance.

Hoping to hear from more experts as your self as local techs are all over the board in there diagnosis contradicting each other of course.

Thanks in advance.
