Vengeance 2100 v2 lights blue, then stops.

[Norways]

My Corsair Vengeance 2100 v2 has stopped working and gives me no sound and the mic dosen't work.
When I press the power button it lights blue for 5 seconds then stops, the charging port continues to
blink as normal while charging and the USB dongle is blinking blue.
This is the headset I got after RMA'ing my old Vengeance 1500 v1 a year ago.

Re-pair the headset to the dongle and see whether that works. Expand the V2000 section)

If that doesn't work, you may need to RMA the headset again. Corsair provides a two year warranty for their headsets from purchase date. So if the V1500 v1 purchase date is still less than two years, you should be able to get the headset replaced.
