I agree with Lee,

switch to the tuner in the receiver to eliminate everything associated with the turntable.

Listen through headphones to make sure the regular part of the receiver is working.

If it is, undo the speaker connections on both ends and reconnect.

If nothing, try one speaker at a time.

If nothing, switch to the alternate outputs, if there are some (A and B)

Make sure that if there is a speaker button (A and B or something) that it hasn't mistakenly been turned off.



good luck!
