Nothing more to check than? if not, do u knowanhthing about dara recovery machine for this models? I saw there was a device that recover data from faulty logic board

PCH_INTRUDER_L - 2.5V PM_BATLOW_L - 3.3V P.S. Also PPVBAT_G3H_CONN is a bit burnt but i get 12.5V. May be it damaged U7000? U7000 on this models comes with firmware, right? So i cannot just take it from any board, it must be same board.

PM_DSW_PWRGD - 3.4V RTC of PCH u mean this?: RTC_RESET_L - 2.7V PCH_SRTCRST_L - 2.7V P.S. Seems that there was overload on PPBUS_HS_CPU because all points of componentes on that line seems be a bit other color ( like burnt), but i get 13V on that line. Also if it can help: connecting...

No, Both stay 0.0V. Only PM_PWRBTN_L drops down

No water damage, logic board is like new. This is the behaviour: First time when logic board is cold it boots ok and load system. All is working fine. When shut it down it stop working. Fan spins, CPU get hot but no image, no chime. In this momento absolutly all rails are present and ok but...

Mac Pro 4.1 (Early 2009) takes about 5 minutes to chime and begin to load OS. After loading everything is ok. Also if i shut down and right after that power it it will boot normally without delay. Things i already done: PRAM reset EFI upgrade Run ASD ( no error) Any ideas?
