Did you bang or sit something heavy on your systems lid?

Sadly, your LCD display driver logic on the back has become slightly dislodged. Which is why when you touch the corner the image gets messed up. There is no means to fix this other than replace the LCD or the entire lid assembly.

That is a TAB error on the LCD, not the board. Neither here not there, still requires a new LCD.


So the LCD panel needs replacing? Sad because obviously the LCD itself is fine..


Here's a bit more on TAB errors: Defective pixel

Read up on how LVDS works, it is either there or it isn't. It's never the cable but the internet will keep telling you that it is the cable because the internet is full of wishful thinking that there is a $5 solution to a $50 problem. That is a bad LCD 100%.
