my problem with the Raspberry Pi Official 7" Display:
In this page I found this:
My display fades out to weird patterns when I shutdown/reboot my Pi.
Don't panic! This is perfectly normal.
It isn't perfectly normal, because I don't shut down or reboot my Pi.
Okay, I have an Official Power Supply and I updated Raspbian (not only).
What can I do?
Edit: I need a new cable. Checked with other cable and it work.
