Witam
płyta jak w temacie (mam samą płytę do naprawy)

MB: DA0NJHMBAH0 rev H
CPU: SRKT1
PCH: SRKMA
GPU: GN20-E3-A1
IT: IT5570VG-128
CHRGER: BQ24780S

płyta dotarła do mnie po jakimś serwisie zwarta gdzie się dało :D
Zwarty PCH - wymieniłem nawet 2
Zwarta przetwornica PU403 (wstawiłęm nową) brak zwarć.
Uszkodzona przetwornica PU1000 - brak 3,3V LDO i 5V LDO
PU7002 była wlutowana obrócona o 90 stopni robiłą zwarcie na szynie 20V.... jak wstawiłem ją jak trzeba zwarcia już nie ma.
Ale kompletnie nic więcej nie widzę.
20V na płytę wchodzi i teraz jest obecne
3,3V LDO i 5VLDO obecne
nie reaguje na power switch
po podłączeniu baterii nie rozpoczyna ładowania
Napięcie na PWRSW mam3,3 ale po zwarciu do masy nawet nie pojawia się żaden pobór prądu.

Nie ma do tego schematu a przynajmniej nie znalazłem. Boardview jest i po nim sprawdzam.
Nie ma zwarcia na RTC
Na zasilaniu GPU mam jakieś 0,3ohm ale jak go zmrażam podnosi się do jakichś 1,3ohm
Na zasilaniu CPU mam 30-40 ohm ale po schłodzeniu leci na 300 więc raczej rdzeń ok.
