Hello guys. I recently became an owner of Vive pro, got it from a VR club with an issue with the left screen. I was planning to buy a (pricey) screen replacement until I started testing it: turning on/off the headset, steamvr and PC and after another launch dead pixels were gone, for about 2 minutes. Another time I was using video player and these 'lines' became black which are much less vissible. So I thought, maybe these pixels aren't dead and it is an issue with the cable or linkbox or display connector inside the headset which needs cleaning or readjusting.
I would appreciate any diagnostic help.
No one in my city repairs VR headsets and I am too afraid to send it across the country to unofficial service center.
