Hi all. We bought 2 helmets at the official website of HTC Vive https://www.vive.com/ru/ at different times (November 2016, January 2017), 2 helmets bought on sale, timed to the anniversary of Vive, https://www.dns-shop.ru/ in April 2017. Had the opportunity to preclude problems PC, location (transferred the system to another room), wires, reinstalled Windiws and Steam vr... the problem with the grey screen persisted after the inclusion of 20 minutes. It's hot 32-34 degrees Celsius. Then we decided to experiment. The cold air stream helmet cooled, and the image appeared in the position of the head in which included a gray screen. Then he sent a jet of hot air on the helmet, and the image began to fade into a gray screen. Now cooled helmet, but this treatment lasts for 10-15 minutes. The problems started from the beginning of June, the number 6 to 8, when we have established very hot weather. Very interesting, are the owners of the HTC Vive this problem with a gray screen right now who is in the room air and the temperature to a comfortable 24 degrees Celsius?
