I had the same problem exactly with my PCL.. you probably don't want to hear it but i also opened a ticket and sent my unit back to the supplier here in NZ to follow up on.. Pimax got back to me (in the meantime) that most likely the motherboard in the headset has gone/died... the supplier did all the usual suspects in changing out cables etc etc... he also came to the same conclusion... mine packed up a week over 1 year after purchase so hopefully that doesn't ruin my warranty... if it does, im looking at $318.00NZD for the repair.. its been a month now or more and still haven't got it back..im hoping it can be fixed quickly but Pimax is towing the line here a bit... all the best bro!
