My rift s melted slightly about a month ago, it didn't power on at all anymore. Yesterday, because I couldn't get a replacement, I decided to open it up and I found the problem. The proximity sensor cable melted and shorted. I disconnected and ripped off the cable (it was already pretty much torn in half) and the headset powered on fully, tracking works as well (I could see through Oculus mirror).
The only problem is is that I cant turn the display on even with override proximity sensor check. I don't know what I can do at this point so this is why I'm asking here.
When I go in Oculus mirror it works as if it would normally, but there's still no display from the actual headset
TLDR; Headset broke and I need to bypass the proximity sensor in hardware.
