Re: flashing grey screen

@John7

 

Did you try cooling the front of the headset (by fan or ice pack) as many of us in this thread have suggested? Since I put a fan in front of my racing rig, I have played dozens of hours (2 hours at a time) of Project Cars with not a single problem. Without the fan, the grey screens started after 20-40 minutes.

 

You could also try covering a sensor on the front as many have suggested. However, this may only buy you a little longer time until you have to cover another (overheating?) sensor.

@kimorra,

Out of curiousity, can you please snap a shot of how your setup looks? I'm genuinely curious.

@VibrantNebula I'm glad that you've connected here. You are Technical Specialist, it's very good. Some of us sent our HDM with this problem to HTC and we still haven't got any news about the analysis of it. Write here please also, what the news about this problem in common.

Re: flashing grey screen

Here's my low-budget racing setup. It's a Logitech G25 with a GT Omega Steering Wheel Stand on its low setting. The fan is the black tower on the far side of the picture. It blows diagonally directly at my face. The temperature in this room is air-conditioned to about 23C.

The lighthouses are mounted about 7' high in opposite corners of the 12'x12' room (to the left on the wall in the picture and behind to the right).

All @Vildan @Aidarpro and others:

 

- Our engineering teams have received the HMDs that were captured.  They are running through and attempting to reproduce the symptoms described in this thread.

 

- At first test the symptoms did not show under normal circumstances.  They have to simulate conditions as described here and in a controlled manner and account for a variety of variables.  This not a simple 5 minute or one hour test, especially if the symptom does not manifest immediately.

 

- The process for any kind of testing requires to be able to reproduce, and since we are only working with a single component (the HMDs that were sent in) in a completely different location, under completely different computing environments, again, these variables need to be accounted for.

 

Where do we stand today:

All samples are being tested.  Our engineers also have other duties that they need to adhere to so everythign needs to be scheduled and conducted properly.

 

These are being looked at and due dilligence is being performed to

a) reproduce the symptom and

b) confirm a cause.

 

Our teams have not uncovered nor reproduced the symptoms for this yet, they will continue to work to do so.

 

In the meantime, I will request that this thread be locked for a small period until which time I have additional news to report.  I wish I had more to report but all I can say is that this is still being actively pursued.

 

Thank you,

John

Re: flashing grey screen

All,

 

I have reopened the thread to new replies.  I believe in open dialog and want it to continue.  This thread is being monitored.  I ask for your trust that as soon as I have more information I will update this thread and elsewhere where necessary.

 

At this time, my most recent update still stands: we are trying to reproduce across several units.  Once testing is complete and full reports are available I will share what I am able.

 

In the spirit of dialog I also request that we all extend respect for the teams that monitor these boards.  We work hard on a number of issues and our number one reason for being is to serve as advocates for our customers and that will never change.  We are a small passionate team and we push to get resolution for our customers.

 

Thank you again for letting us work with you and being a part of the Vive family. 

 

Thank you,

John

Re: flashing grey screen

To reproduce, keep room temperature high, play a sitted game, and keep looking at one of the stations directly. Symptoms show up after about 30 minutes.

I suspect that the overheating only occurs when most of the sensors are activated and the headset chips are running at full capacity.

Re: flashing grey screen

Big Thank you @jagibson for answers.

it is noteworthy that,

I also have many other things to do and therefore i had limited time for tests, but i can have managed do it and made more fully review of my tests than yours (i had pictures, videos and annotations).

Okay, i will wait news.

Re: flashing grey screen

Hello everyone, i sent my HDM to tests and got the replacment HDM from HTC. So , for now, it works fine. My Children had 2.5 playhours. In the same time, the tempreature was about 26-27C, and the tempreature of the HDM's front panel was 39.7 - 39.9C. (When the problem started, it was 31-33 С temp in the room, and 41 С front panel.)

I hope, it didn't connect with the tempreature, and my Hdm would work fine days after days :)

I hope HTC can find out the reason of this problem. By the way, if my new HDM wuold work fine, it means, that the others parts of Vive are not connect with the problem.  If this information is true, the HTC team would solve the problem more faster.

During 1 month i'm going to test several times.  I think soon this problem will be solved

Re: flashing grey screen

Thanks for info @Vildan!

Which firm took your HMD and gave it a new one?
Could you look the date of assembling a new helmet?

thanks adnvance for answer.

Re: flashing grey screen

Aidar, I'll try to look it in the evening. I sent my hdm to HTC center in Romania and the sent me back theyreplacement. Honesty speaking, it isn't important for me, if I got back a new one, or I got back just hdm, which was in using, but which works fine. The main important thing, is that they have my hdm to test, and I have hdm, which works good. And I believe , they can solve this problem :)

Re: flashing grey screen

I have just started experiencing the same issue on my Vive.  The room temperature was only about 27 degrees celcius.  I also blasted the A/C to get the temperature down to around 20 degrees and the problem still persisted.

 

I've narrowed it down to the two sensors beside the front facing camera, and if I put black electrical tape over those two sensors the headset will behave normally.  But this doesn't seem like a viable long term solution.

 

I purchased my vive in March, 2017 and the serial number is:

S/N: FA6C7JJ01906   2016/12

 

Is there any official word for HTC regarding what to do about it? I happy to RMA the device if necesary, however I'm also developing VR content and can't go too long without the headset. An exchange type of thing like the video card manufacturers do would be amazing.
