Receiver shuts off at higher volumes
The receiver may be too under powered for your speakers or the speaker ohm's may not be matched for your amp.
The reason it is shutting off is likely because the amp is becoming overloaded. At lower volumes the amp can handle the load of the speakers, but at higher volumes the power supply of the amp can't keep up with the power demand the speakers are pulling.
If you were previously able to turn the reciever high without turning off, then there is likley something wrong with the amp or possibly a blown speaker.
Try measuring the resistance of the speakers if you have access to a multimeter. They should normally read 8 ohms for home speakers, but some common home speaker impedances in order from (I'm assuming) most common to least common are are 8, 4, 2(bose), and sometimes 10 or 12 ohms. The lower the number of ohms, the more power the amp will need to put to the speakers and the more chance you could be overloading your amp.
