flashing grey screen

Re: flashing grey screen

Hello!
I started an experiment a couple of weeks ago - I closed 2 sensors:

After that the gray flashes ceased to appear. I do not know how much this would have been enough, but I played until 3 o'clock and did not see the gray screen.

But I notice or it seems to me, there is a slight tremor of the helmet and controllers.

 

Yesterday i have recieve from HTC another cable 3in1:

(left is has buyed with HMD set, right is cable sent by HTC)

I removed stickers from 2 sensors, and begin the test.

Unfortunately, an hour later a gray screen appeared.

Do you have a security camera with IR/night vision in the room that confuses the headset?

Re: flashing grey screen

I can confirm what @echeva wrote. When the grey flickers start appearing, the mirror screen on the desktop still behave as normal and the HMD position keeps being tracked in the mirror display on the monitor with no flickers. Only inside the HMD there is flickers. Maybe this information can lead engineers in the right direction to find the cause of the issue.

I cannot confirm what @stikaz and @echeva wrote .
You can see on my video that while flashing grey on the HMD, on the display also flashing (https://youtu.be/hGSZZK5cnFc). But it only in "Headset mirror" window, In the game window there isn't grey flashing. If i hold HMD in the zone when appear grey screen several seconds, then the picture in the game window will be freeze.

@Aidarpro
I'll check it again. It could be that I confused between the mirror screen and the game screen on the monitor. Aidarpro description makes more logical sense. Unfortunately I am not home for about one week.

Re: flashing grey screen

@stikaz @Aidarpro The same here, I also have to recheck that and I am also away now.

Hey Aidarpro,

 

I also received a new 3-in-1 cable from HTC and did some testing tonight. There doesn't seem to be any improvement for you with the new cable. I only played for one hour but didn't have any tracking issue during my play session. It was however a cool day and the front part of the headset did not feel as hot as usual. I will re-test it tomorrow for a longer period of time and inform you of the results.

Re: flashing grey screen

I just played for 1h15-1h30 today and started to get the grey screen with the new 3-in-1 cable HTC sent me.

 

It looks like I'm in the same situation as you @Aidarpro

Re: flashing grey screen

Hi everybody

 

Like others here I'm in contact with John and today I received an HMD from HTC Regenersis (Repair station Romania) after sending mine in for testing in the Lab in Taiwan - the exchanged unit has the same serial number like my old one, but it seems to be an exchanged HMD unit (serial No. sticker is not in the same position). The cable seems to be the same (3in1 with my marker).
There is a firmware upgrade recommended, but I didn't do the upgrade until now. 
I tested 30min and also 60min (didn't have the time for 2h+, had to watch my kids today Smiley Wink )

 

environment:
- room temp is around 23.7°C (around 3°C lower than my last tests with my original unit)
- I tested with the "old" firmware, that came with the exchanged headset 
- I tested one session 30min with the old cable and 60min with the new cable I received from HTC
- no changes made in software, except a windows update yesterday (should have no effect)
- no HW changes
- no covering of reflective surfaces
- same chair, monitor and furniture as ever (same environment)
- no changes in position of the lighthouses
- tested with all HOTAS controllers like last time
 
Here is the result:
- no issues detected during both tests (30min and 60min Eve: Valkyrie) - I couldn't reproduce the error, but I have to test it again for 2h+ 
--> no issues in tracking
--> lighthouses were never grey in SteamVR overlay
- HMD is still getting hot during the test, but still no issues detected 

Here some detail info regarding the HMD firmware versions:

At the moment I'm waiting for information about what the exchanged HMD exactly is and if there is news about the root cause and if they where able to reproduce the issue with my HMD, that I sent in.

I will do some stress tests over a longer time when I have a time slot. Could take some days until I can do a real 2-3h test.

 

all best

Just for information to all users, that are affected: I also informed the HTC CEO and the Head of HTC Creative Labs about this thread - just to be sure, that there is enough attention to a possible design mistake.

Thank you for the information! Glad you got your new headset and it's working. We'll have to see when you give the longer test run, but I'm remaining positive.

Have a good weekend, everyone!

Re: flashing grey screen

I'm finding it impossible to believe that HTC have been unable to reproduce this issue and cannot figure out what it is. I bet they know what it is but don't know how to fix it and haven't owned up to it. This thread alone has been around for too long for the issue to still be "a mystery" to their engineers. Give me a break.
