I always have such purple lines when I boot my device and I can't see anything anymore. When booting the logo is briefly visible but when it goes to the login everything is gone and these lines appear.

This was a common issue with the 2016 models. Apple rev’d the display assembly and the problem appears to have been resolved. Sadly its too late to get this fixed as you’ll be on the hook for the new display assembly - Sorry ;-{
