hi, i was playing my receiver and next to the power light their is a overload light. if you turn the volume up too much the overload light flickers a bit which i kept the volume down enough to keep the light off. but went to turn on the receiver and nothing. everything comes on but no sound and the overload light is on. i took the lid off to see if their were a reset button but nothing and their are three fuses and they are all ok. can someone help please.
