hi, please helpme this motherboard when plug the power cable fisrt led its power on but When I press the power button the second LED turns on for a second and goes out * audio codec was shorted and reheat I replace but no lucky any suggestion
No schematic available.
I suppose 820-00034 could be close enough.
If LE0302 flashes, means ALL_SYS_PWRGD comes on in that moment.
Then all S3 and some S0 voltages should pulse too.
Maybe not the CPU ones.
Check for pulse at all big coils.
Do you get high pulse (20V aprox) at FET_EN_P12V_S0?
Also check if PP12V_S0_FET rises to 12V.
Be sure no short on any power rail; especially on page 63.
