Hello, Welcome to Microsoft Q&A,
If the 1st, 3rd, and 5th lights flash together continually, your HoloLens may have a hardware failure. Please contact support: http://aka.ms/hololenssupport
For future reference, the hololens-development tag is for questions about programming HoloLens apps. HoloLens device support is not currently available on Q&A.
