Remove all speakers cables or wires and check all from behind the Receiver. if there are any loose terminals or any metal object in between the terminals.
though it might be a coincidence that you have a problem in the Receiver.
unplug the power cable from the wall socket and remove all cables.

after you remove the cables plug the power cable in the wall socket and try if you see the protection displayed , the receiver needs service.
Good Luck
