That means that the receivers' overload protection circuitry has been engaged. Depending on the number that is also displayed after the alarm message, there are several causes for this. Overheating, running inefficient speakers such as below approximately 85dB/1W/M rating or too loud a volume with demanding source material and last but not least a loose connection of any kind on the rear panel or on any of the devices connected to it. Especially the speaker cable.
This means that one (or maybe more) of the amplifiers is shorted. Remove all speakers cables and try again. If you get the same message that means that one (or more) amplifiers is fried. To find which and why you will have to open the unit and test the amplifiers.
Check your speaker connections for a possible short circuit. Best way to do this is to remove all speaker connections (with the device turned off) and then try turning the device on. If you now don't get the overload message then it means one of the speaker connections or speakers is faulty.
From here add one speaker at a time (always with the device turned off when you plug each speaker in) until you find the offending connection.
If it not a speaker connection causing the overload you should check all other connected devices in a similar way.
If none of these things identifies a problem with a connection or connected device then there is an internal problem with the receiver.
Disconnect all speakers at the receiver then turn the unit back on. If it stays on, post a comment and I will walk you thru troubleshooting. If it still shows "overload" it needs to be serviced. Hope this helps
