I just bought a htc vive head sett, no cables or anything for 100$ I Have a 3.5mm 1-.3mm 12v power supply that i plugged right in too the head sett, but there is no indication off life, not even light in the led bulb. Is the led supposed to light up if only the power supply is connected?? Im afraid i bought a broken headsett :/
