Usterka prawdopodobnie znaleziona na VPP25 powinno być 2,5V a jest 5V .Zamówiłem już MP2145 na wymianę.

Po wymianie MP2145 pojawiło się 2,5V na VPP25 oraz napięcie na pamięci i procesorze. Na VCCGT 0V . Brak sygnału PWM z kontrolera procesora jest tylko płaski sygnał 1,8V . Co robić dalej podmienić kontroler procesora ??

Płyta naprawiona , problemem okazał się źle zaprogramowany bios . Chiński wynalazek CH341A nie poradził sobie z W25Q128FV.
