820-3476 power cycling

[Aivaras]

Hello,

I have liquid damaged 820-3476. Which is power cycling.

Vcore is present

It seems that spi_mlb_clk and spi_mlb_mosi only present when board is turned off. When it trys to turn on I get 0v on those.

Any ideas what going on? Bad traces?

"When it trys to turn on I get 0v on those."
That's good; so simple to compare with any other working board...

Where was the liquid spill?
Did you try new BIOS?
Try to start in SMC bypass also.
