Please I’m looking for schematic (circuit diagram) for Siemens board part number (6SC6600-4GA00), can anyone help by telling me where I can find that file over the net or if anyone can give me the part numbers for the burned transistor I have, because I have 4 bad Power Transistors (totally burned, toasted) I can’t read the part number, their place in the board are (V111, V116, V140 and V406)

Thanks
