When i switch on my samsung HT-Z110 the word hello appears then protect thenit turned off!
Audio receivers have an output protection circuit called "protect mode", this is to protect the receiver from short circuit failures.The speakers and speaker wires are what I inspect thoroughly first, look for bare speaker wires,or bare wires that are touching each other at that point,check speaker wires at the back of the receiver for sloppy connections,etc.If all looks good then try disconnecting all the speakers at the receiver,then turn power on to see if it goes into "protect mode", if it does the the receiver probably has an internal short and will need to be sent in for service,if it doesn't go into "protect mode" then connect one speaker at a time back into the receiver until it does go into "protect mode" then which ever speaker you connected last is the speaker that is shorted(blown) and then you know that speaker is the problem and it will need to be replaced or repaired. Good luck !
