Protect appears when the receiver is cut on. what does that mean?
I just wrote the reply below for someone who is having the same problem with their receiver than you are. So here it is. Enjoy. I hope it is a help to you.
Here is some theory as to why this is happening to your receiver.
The "protect" mode is designed to respond to several related conditions:
The first reason
is a wiring fault between the receiver and the speakers such as a strand
of speaker wiring touching the opposite conductor so that there is a
short circuit. If this happens the receiver will overheat and then shut
down to protect itself. This is a good thing. otherwise you simply
have a very expensive repair on your hands.
The second reason
happens when the receiver is inside a closed cabinet and overheats
because not enough air is going through it to keep it cool. So it shuts
down in this circumstance.
The third reason happens when the receiver is playing loudly beyond the limit of it's design. In this case, it will overheat and thus shut down to protect itself.
Here is a diagnostic procedure for the first reason above:
What we are doing, in this case is looking for a shorted out speaker system, or wiring to speakers,
or cables or components that are connected to the receiver that have a
short circuit. This is what I would do if I were called to your house to
debug your sound system.
1 Disconnect one set of speakers at the back of the receiver and turn the power button on again. See if it stays on.
2 If not, remove the next speaker and keep repeating the test.
3 If it still stays off, disconnect all of the equipment connected to the unit, one piece at at time.
Somewhere along the line, the receiver may not shut down. If that is the case
identify the the offending cable(or component)and replace or service it.
To correct the second reason
simply leave the cabinet door open while the system is playing. The
only problem with this solution is that if you don't have cabinet, it
makes no sense.
To correct the third reason. Watch the volume level while using the system.
I hope this helps you.
