Hi Wayne

I reset the SMC (turned off the battery without power cable and pressed the power button for 5 seconds). When I started the vertical bar was gone. Five minutes later she returned. I returned to perform the procedure and also ran the reset NVRAM / PRAM with command + option + P + R

So far this functioning normally, without the vertical bar.

I'll wait

seems like hardware. try cooling the display to see if it is heat related. Maybe it is a loose cable? does the band change if you slighly open or close the lid?

I didn't mean fully close and open I meant slightly. Just move the screen back and forth a little to see if this is a failing cable. All indications are a connection problem.

Not .. Slightly moved a cover and did not cause the problem. But the problem is when I close the lid completely and the problem disappears.
