Vertical Colour Line appeared in MBP2013

Hi,
anyone has same problem as mine.

there is a vertical line in my MPB2013 screen. it is not consistently there but randomly appeared.

I tried SMC/PRAM the mac, the problem is still here.

Is it a graphic card issue or LCD issue or some kind of hardware/software/firmware issue?

Which 2013 MBP model is this?

When you plug your laptop to an external monitor, is the line still there?

Its 2013 middle year 13' Retina Version.

I don't have external monitor. the line is not consistently there. it may appear a few seconds and disappear. after a while appear again, then disappear again.

Graphics cards rarely (or never) fail in such a way that only a single pixel line is affected while the rest of the display image remains fine. That's almost certainly a display issue. On a Retina that means replacement of the display clamshell would be required.

thank you. will send the mbp to servicer centre. but the problem doesn't always appear, not sure the staff will accept or not. :-(.
