1.latly, the computer started to display strange purple horizontal lines. 2. it's stuck on 60% bar on startup and wont boot 3. if i try recovery i cant see any recovery partition 4. if i try internet recovery it wont reach the utilities window. i get blank screen (without the purple lines!) and then nothing i attached i video with verbose mode on right after the internet recovery. https://youtu.be/eyTeshw5obY
The first thing I'd try is booting from a clone or other external bootable volume, and I'd next run Apple Hardware Test which, depending upon which MBP you've got, is either on a disk or on your machine.
Please let us know how you make out in both respects.
