Macbook Pro 15" Retina 2015

I'm having a problem with my MBP that I bought last 3 months.
I'm experiencing this random blackout on my screen but the music is still on.
I notice this every time my external monitor is unplugged.

Any has the same problem with me?

Does the screen flash black then back to normal when you unplug the external monitor or does the screen stay black?

Nope, I have to force shutdown the system.
But everytime I plug the external monitor the problem has never occurred.

Have you tried turning off the monitor before unplugging it?
[doublepost=1476277441][/doublepost]Do you have the external monitor mirrored with the internal monitor or in two different spaces? (Check the monitors preference pane.) If they are in separate spaces, when you get the black screen try a two finger scroll left or right with the track pad to see if it brings up the space for your internal monitor.

It only happens when the external monitor is unplugged.
The problem never occurs for weeks if I'm using the external monitor. But if its plugged it'll be fine only by days then the problem is on again.
