Black Screen of Death issue

A while ago, I bought replacement parts for my Quest 3, specifically the IR emitter and receiver, because I got the Black Screen of Death. After the parts arrived, I replaced them, and the BSoD persists. I've already tried looking at the hardware, and everything looks in tact. I've also tried factory resetting the headset, but nothing changed. I want to try fast boot mode, but I'm afraid that my headset will get bricked. I can't look at the settings via USB - C, but because of the factory reset, the setting was switched off. What else can I try to fix it, and is fast boot mode a viable option?
