Re: Lenovo Explorer: HMD screen turns black randomly and only restarting helps

For me the problem nearly disappeared when I turned off the "allow the computer to turn off device to save power" for the driver in the Device Manager ("Device Manager>Mixed Reality devices", side note: some Windows updates can turn it back on), end updated to the latest Steam, Windows Mixed Reality for SteamVR. Also in SteamVR I set the turn off displays("Settings>Power Management>Turn off displays:") to the maximum value (I think 10 minutes"). Since that the random black screen only happens very rarely (2 times in the last three month) and it fixes it self in 1 or 2 sec (I'm not sure if this is the same issue i was facing before). I suspect for same reason the computer think the display is not moving and turns off the display to save power but I'm not sure. Hope this helps you.

Re: Lenovo Explorer: HMD screen turns black randomly and only restarting helps

Thanks for the reply. This option also doesn't work. Still getting black screens. I tried to find the field where i can raise a ticket for an repair order. But I'm stuck in a loop on the lenove support website. Can someone help me to solve this issue. Or tell me how i can open up a repair / exchange or even found back order for my lenovo glases on warrenty?

Could you find a solution for your problem? My Lenovo is having the same symptoms.

The support site say's that i still have warranty, but i can't get a repair ticket.

Re: Lenovo Explorer: HMD screen turns black randomly and only restarting helps

I have had this same issue recently and for me I think I know what the cause is but not a good solution so perhaps this will help someone.  The issue for me seems to be static electricity is causing the headset to black out.  I had noticed that it happens more often when I get up or move around a lot.  The issue wasn't happening when the weather was more humid but is happening now that it is dry.  I also think my audio headphones have something to do with this as they act as a path for the shock to get into the headset.  I had noticed when the headset blacked out I heard a small pop but not that noticable and no other symptoms.  Since that started (and it got more dry) I have gotten static shocks around my audio headphones at the moment of blackout.  I tested the headset without headphones on and it seems more tolerante to static.  

My guess is the headset is insulated to prevent static from messing it up but when I put on audio headphones they are the path of least resistance.  This enables the shock to propagate through the audio connector and cause my blackout issue. 

 

Before this I tried changing the refresh rate but it made no difference and oddly enough when I start wmr with my computer set to 60 it says the hdmi cable isn't connected but then works fine at 90 and after that I can change back to 60.  Going to 60 made no difference with the blackouts anyhow so I just keep it at 90.

 

As others it keeps tracking but the screen goes black and after it blacks out the only thing I can do to get it to work again is close and restart wmr to get it back.
