I just bought a used Lenovo Explorer, and while it is a bit finicky and missing some external parts,, it is in great physical condition. However, upon plugging it in and setting it up, only the left half of the right screen is turning on. I have tried adjusting all of the WMR display settings, and I took apart the headset to check the connections of all the cables, and the issue is persisting. If anyone could help out with this, that would be great.

Update: I tested out the headset on a friend's PC, and the same issue still occurred, so this is most likely a hardware issue. If I could fix this myself somehow, that would be amazing. If not, where, if anywhere, would I be able to send the headset for repair/replacement?

Update: After fiddling around a bit more inside the headset, I managed to get the whole right eye to work. I think the issue was a small bit of tape covering part of the ribbon connector, but I am not sure. I'm still not sure what is wrong with the left eye.

Update: After carefully taking apart everything I possibly could, and trying to find problems, I decided to return the headset, and I will probably buy a new one soon. Thanks to everyone who responded for your help.
