Flickering and horizontal lines

Flickering and horizontal lines

I have a Sony EX400 which has flickering and some horizontal lines run across ... the technicians tell me that I have to change the panel. Wondering if this is something else. And sometime the screen goes blank( black). Attaching a picture of the problem

ANSWERS:

Saju Thomas that looks like failed gate drivers on your panel. Post some images of all of our boards with our question. That way we can see what you see. The gate drivers are part of your LCD panel....
