If your VR Headset displays only three white dots, you cannot enter the main screen of the system. Or when wearing a VR headset, it is often unable to wake up the system normally, which is generally a failure of the induction function, and the damage of the photosensitive flex cable and the photosensitive flex extension cable of the head display may occur. These two types of cables can be found in the store. This link sells induction soft extension cables. One end of the cable is connected to the main board, and the other end is connected to the photosensitive flex cable. The back of the cable is provided with double-sided tape for pasting on the battery to play a fixed role.
