Retrace all your connections while studying those diagrams in the operating manual. That's for starters...
I have an 6 year old Aiwa receiver (looking for model#) but I am not sure if it's working right. When I turn on the Dolbey 5.1 srround, I get sound from my rear speakers, I get the main voices from the center speaker but nothing from the front left and right speakers. What type of noise usually comes from those speakers?
If I turn the radio or CD player on, the same speakers do work.
Can someone tell me what I'm missing or how to test them?
