Hi, Asus X555LD Rev 3.3 motherboard, with all main voltages and no image.
After cleaned it and test with a good new bios dump, keeps the same.
Debug card shows nothing in its display, only the dot led is on.
BUF_PLT_RST#_R1 on wifi connector is at low level, SM_DRAMRST# is at low level also.
XTAL 32.768KHZ circuit is working properly but XTAL 24MHZ, (XTAL24_OUT) has 1/3 of amplitud than XTAL 27MHZ (XTALOUT_C) on GPU nvidia oscilator.
I have the boardview and repair guide fro asus, but need a similar schematic from asus or other brand in order to follow the circuits.
CPU damaged?
Thanks for your help.
