Magnat Bull Power 4600 schematic

[brucce]

I need a schematic for Magnat Bull Power 4600. It don't works. There was a short circuit on spearkers output. I changed a 2SC transistor, but it doesn't do anithing. The protection is flash for a second, then switches off. There is no power supply. I think the protector IC doesn't do AC for it. If you can help me, please send me a mail or a schematic.
