@livfe those lines originate from a loss of contact between the source driver COF and the LCD panel. The COF is connected to the source driver board (long, skinny circuit board) and the LCD. If a single point on this COF looses contact, you get those lines. Sometimes a bit of pressure on the COF right on the area where the line appears, may re-established contact. Sometimes it is enough to just wedge a piece of thermal pad between the COF and the display housing, to (temporarily) "fix" this. We'd have to see the location of that specific COF and what it looks like in relation to the LCD housing.

This error will not be related to any cable that can be removed or be reseated. COF's are in a fixed position.
The Apple part number for the display is 661-07323 The panel itself is a LG display model LM270QQ1(SD)(C1)
