Grendel

I've had the original Vive for about 2 years now. When I connected it up today to play, the head set was unable to be detected. After connecting to my pc and power, the red light doesn't come on. I checked all connections, reset the pc, and even took the front cover off to check those connections. But nothing I do seems to fix it. Do I need to replace my power adapter? Where can I find one?
