There vertical lines on the left side of the screen

@namranamra that depends on what those lines look like. If they are single pixel wide lines then it is possibly that 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 loses 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.
