Macbook white screen of death not able to boot
If your Mac shows a white screen in recovery mode or internet recovery then there is a hardware issue on your mac.

My recommendation is to either contact Apple Support for an appointment or set up an appointment yourself via https://getsupport.apple.com/.

This could be a hard drive or display issue. If not then you are looking at a logic board replacement.

If you have a time machine backup or a separate backup of your things
elsewhere then you should be fine, if not then you'll want to get the hard drive (if that is the issue) taken out and then purchase a new one, so you can take your current hard drive to the nearest data recovery center nearby you.
