Faint vertical line on one eye

The headset was working perfect, but at some moment a faint line apeared on the right eye. It’s a minor anoyance while using it, but I would like to have it fixed. I have a picture from the headset.


does anyone have any idea about a fix or something?

btw, the device and the cable are intact, it didn’t get hit or anything like that. It just appeared from one day to another.
