I have a C1000 which won't power up. I found F3, a 5x20mm 5A fast fuse, blown. After replacing it, F103, a 5x20mm 500mA fast fuse hidden under the power inlet, blew when I applied power, but before I turned on the power switch.

Its jarring that I found the exact same issue nearly a year later after doing the same thing. Assistance from anybody would be Much appreciated.

Olá, primeiro voce tem que acertar os erros na entrada.é complicado de explicar, esta placa tem PFC e conversor DC-DC, precisa seguir o esquema eletrico do manual. esta tua placa é a antiga pelo jeito.
verifica se esta em curto Q3; Q4 e Q6, UCC3817 = U5 PFC aciona U4 TC4452 que chaveia o Q3
DC-DC U6 = UC2825B; U2 = TC4452; U8 = TC4452 Chaveia o Q4 e Q6
verifica os capacitores NF e UF ao redor.
