I'm having major problems with my CV1. First of all the Display would sometimes cut out and tells me that there is no HDMI connection. This goes away after a few times of unplugging it in and out for some reason. I tested my HDMI port with external displays and there is never any issue so it must be something to do with the Rift.
Secondly, I get "guardian systems isn't working at the moment. Click here to check our article" error. It doesn't bring me to any page. I reinstalled the software twice and recalibrated about 10 times. Upon restarting the system it usually works for the first time. But the second I take it off I get the error and everything breaks.
I am a Unity developer on a tight schedule and I can't afford to lose days to trying to fix it like I did yesterday. I have the Rift since December and the issues began to appear in the last 4 days and have been getting progressively worst. Headset is sitting on my table all the time. It has never been banged so I suppose that this isn't a hardware issue. The sensors never move.
I read the forum posts about similar issues but have found no help. I tried looking into the log files but haven't found anything that would suggest errors.
It is possible you need to remove the foam cushion from the headset and re-seat the HDMI connection on the Rift. This can make the HDMI connection spotty.
