schemtaic or repair manual Pioneer Elite VSX33TX THX

[scwrx02]

hello,
i am searching for any repair manuals or schematics for the Pioneer Elite VSX33TX home reciever. the problem i have is that the unit turns on for about 3 seconds then shuts off, i can hear the relay on the AWX7563 primary power PCB, this will not allow 110Vac to go to the main huge transformer when it is connected to this PCB but whe i remove the wires the voltage is there...??? any help would be greatful
thanks
