defective Embedded Controller MSI GF63

[Patrick501]

Hello,

I located a defective EC (IT557VG-128)on a MS-16R81 2.0 board of a MSI Thin GF63 12U. The board doesn't have any voltages except the 19V power line.
Some Caps and resistors around the EC show less than 2 ohms. One of them is a 3V rail. When I inject 1V@1A the EC heats up.
I'm pretty sure I can't just buy and replace it since it probably needs the correct firmware on it.
Does anyone of you guys know?

i replaced 5570 and it program itself from bios. so chance is high that u dont need to program it

thanks for your answer.
I will give it a try then. I removed the EC today and the shorts are gone.
What I'm concerned about is that two CPU coils show a very low resistance to gnd. I know cpu rails can be low but 0.7ohms on this isn't very much.

with never gpus and cpus u cannot use common ohmmeter because resitance under 0.5ohm is normal. u must use miliohmmeter, but dont bother with it and just replace EC
