Dzień dobry , szanowni Koledzy na forum, jako ,że jest to mój pierwszy post jeśli chodzi o naprawę płyty bardzo proszę o wyrozumiałość :) .Płyta jak w tytule(jak widzę bardzo znana ) , startuje, podświetla się klawiatura i na tym koniec, brak obrazu, pobór prądu stoi na 0,422 A. Są wszystkie napięcia na cewkach oprócz zasilania CPU . tranzystory w gałęzi zasilania procesora raczej nie wykazują zwarcia.Rezystancja na cewkach PLZ1-4 2,5 ohm, PLG1 5,6 ohm . Załączam, foto z pomiarów . Płyta nie grzebana jeszcze, będę wdzięczny za podpowiedź co ewentualnie sprawdzić ... lub wyrok na CPU :)
