Witam.
Problem dotyczy zasilacza B512431-2. Wymieniłem diody prostownicze D101, D102 lecz po podczas uruchamiania urządzenia ponownie uległy one przepaleniu. Procedurę powtórzyłem, lecz za drugim razem odłączyłem grzałkę fusera. Tym razem diody nie uległy przepaleniu, aczkolwiek były bardzo gorące. Domyślam się, że jakiś element robi zwarcie lecz nie bardzo wiem jaki.
Za sugestie od razu z góry dziękuję. Pozdrawiam!
