Are you getting a light on the HMD? Did it work previously on an older computer? If so, does it still work on the old computer? Have you tried bypassing the 3-in-1 with another (known good) HDMI and USB cable to isolate the HMD or the 3-in-1?

If your base station has a Fault 02/03 error or a red light or both, the ONLY solution is to contact our support on vive.com and set up an RMA. There is no user fix for this issue.
