My first post so be gentle.
15" MBP Retina (late 2012)... water damage took out the I/O Board (melted the I/O cable). Removed cable and board. Also killed the SSD (wouldn't boot from another Retina). Localized corrosion removed. Applied power and attempted boot from external usb hdd. Dies after 3-5 seconds of power. Reset SMC and PRAM. Fans now on high, but still dies after 3-5 seconds. Ran Apple HW test. Shows "no problems with the logic board."
Huh?
Won't boot to Safe Mode.
Starts booting to Recovery but as soon as it looks for a place to install, total shutdown executes.
My brain says SMC. Will SMC operate as normal with no I/O board? Waiting for a replacement board and cable.
Many thanks to all kind responses.
