Motherboard Model: DAY31AMB6C0 REV C
I was able to find out the boardview and the schematics from the forum. I see there is a short but I can't find out where it is. all the 3v 5v 19.5 are short to ground. when I remove 3v step down regulator, 19v rail is okay but still 3v & 5v inductors short to ground but only LDO signal from 5v chip okay.
I injected 1v to 3v rail and I was able to see that CPU is heating.
Can you guys help me to fix this. I really want to fix this motherboard.
Special: I shorted power switch pin 1 to ground by mistake. Thats the cause to happen this. When I see schematic pin 1 is 3vpcu.
Anyone can help please???
