I plugged in a 12V power supply into my 4B and the green light did weird things but going back to the stock power supply, green only flashes on and then goes right back off. I tried a diff power supply and did the EEPROM trick that AI told me to try. I don't get any green light except the flash when no SD card is in. I tried using a multimeter and saw a video about checking TP1 and TP2 and they're getting ~5V. I feel like the audio hardware is fried but AI also told me that shouldn't affect booting. Thoughts?
