Demon and won't work

Solution
If the Denon receiver goes into protection with nothing connected to it then the problem is inside the receiver.
If it doesn't then there could be a bad speaker or shorted speaker cable. Connect the speaker cables one at a time. When the receiver doesn't turn on then you know which wire or speaker is the problem. Check that there aren't any stray wires that could be shorting from plus to minus at either end of the speaker wire.
