Hi, I'm just working when it happens so I'm not sure how it's possible that it is hardware issue? There's a flickering on my screen then multiple lines with black background that will appear on the top of the screen then later on, it will appear on my whole screen but when I connect it to external monitor, it works perfect fine. Have anyone encounter that issue?
Thank you so much.
Mac Pro
See if the flickers changes when you change the angle of the monitor. That would indicate that display cable is failing rather than the display itself.
If this is a Retina MBP it is a moot point because those require replacing the entire display assembly in the cable is bad. If this is an older (pre-2013) non-Retina MacBook Pro, the cable can be separately replaced without the steep cost of a complete display assembly.

Hi guys, thank you for your response. Yes. After rebooting it. Still the same. I think I need to go to mac repair but coz of covid19 still cannot 😢 It will affect my work. Yes, macbook pro retina 2017.
Here's what it look like:
then later on, it will affect the whole screen.
If an external display is working fine, then it most likely means the built-in display is defective and the laptop needs to be repaired.
Flicker - hardware issue?
