Power supply type BN96-03775A
This set came in with blown PFC-IC ICP801, DP804, DZP801, DP803 QS802, diodes ZDS805 and DS804.
For QS802 I fitted a BC337 (reverse to drawing on pcb), and for ICP801 TDA4863 I fitted an L6565 (IRF7134) used in Vestel power supplies, as here I couldn't locate originals. Wasn't really sure about the L6565 and looking at the schematic seemed to have the same pinout and working conditions, the set worked and I'm giving it a good soak test.
Resuming TDA4863G = L6562D (IRF7134)??
Correct me if I'm wrong.
Another Samsung that came in, had the blue led going on and off, this was traced to DS806 18V zener open circuit.
