I received an Xbox one, 1st gen, but the newer rev.h motherboard. There seems to have been a power surge over the hdmi. It blew the hdmi coils, and the southbridge was shorted.
I have replaced the southbridge, removed the hdmi coils, and a voltage regulator that goes to pin 18 on hdmi out. Now the xbox turns on but only for a brief second. I can not seem to find any other shorts, or faults.
Does the hdmi out come from the gcpu? Could it have damaged the cpu? I get all voltages to the cpu and ram for a brief second, and nothing seems shorted at all.
