Dreamst8 has good suggestions. I'd also check to see if any speaker wire strands are touching another binding post (which will trip protection circuit).
Is the receiver pluged into a surge protector?
Your receiver may have taken a power surge hit and be fried.
Last week, my TV wouldn't turn on (plugged into an Adcom ACE-515 -over 15 years old).
I felt it might be a voltage thing so I plugged the TV directly into the wall socket and it worked.
Lastly, turn off the power to the wall outlet and check the receptical. Specifically, use steel wool (or tarnex tarnish remover) to get the AC wires back to shiny metal then reconnect (why not replace receptical with hospital grade or fancy audiophile type while you're at it?).
Let us know if any of this works...
