Sony xbr 75x850e flashing lines

[65caliente]

Here is a video of the problem. I have replaced every board to no avail. There is no visible screen damage. Pressing on the bottom ribbon cables does nothing. The tcon board makes a faint screeching noise when the lines are present on the screen. Thanks

Why is your TV sideways?

Because it has no stand and was examining the ribbons on the bottom. This issue developed on the wall.
