Great presentation. My screen develops purple and pink vertical lines and no picture but if I adjust screen backward or forwards it clears up…but the problem is getting worse. Another observation is that if I apply a lot of pressure on area between the power button and the left hinge that it will clear up at certain angles of the screen.
Is it possible/probable that I have a loose connection below that pressure point where the screen cable connects with the computer board or is it more likely that the cable has simply worn out and the wires are actually breaking? Or is there another conclusion?
