Witam!

PS4 po uderzeniu piorunem przestała reagować na włącznik. Przy naciśnięciu CD-Eject pika 3 razy i dalej 0 reakcji. Sprawdziłem:

-wszystkie bezpieczniki sprawdzone, są OK
-zasilacz po zwarciu 1 i 3 pinu zasilacz wstaje, podaje 12 V)
-na zasilaczu serwisowym płyta pobiera 12V sztywno 0,1 A
-brak zwarć na cewkach
-po podaniu 12V z zasilacza serwisowego 12V, 5V, 3V, 1V obecne (mierzone w sekcji przy złączu SATA)
- 3V obecne na pinie 1,2 SYSCON)
- 3V obecne na włączniku
-wylutowałem sterownik HDMI (bez zmian)
-sprawdziłem wszystkie kondensatory pod kątem zwarć do masy, są wszystkie ok, i na tych przy układach BGA obecne 3V (poza 3 kondensatorami koło sterownika DVD - wlutowane są w piny, które z obu stron są masą - po jaką cholerę one w ogóle są ?)

Bardzo proszę o pomoc w lokalizacji usterki
