5 purple and between them there is a black vertical line and screen is blinking.

I'm not sure about the model year.
But it's the one with 2 x USB-C on the left side and no other connection options.

I have tried all the common tips like Nvram, safe mode and other stuff.
Think there is 4 or 5 things you neeed to try before.
External screen connected with the USB-C. No signal on screen. Actually does not seem to be any connection.

Probably the graphic card is broken.
I was just wondering if it could be similar problem as my old Imac 2009 had.

Graphic card out and bake it in the oven 10 min. The gpu connections then get connection again.
Something like that.
I did that several times with my 2009, 2010 and 2011 imacs... and it worked.

Anyone had tried this or something else that could get the macbook back to life?
 
Hmmm...after 1 hour with the purple screen it's now shifted to apple login :eek::):p
