Usally When something like this occurs its because the amp cant handle the reciever. Meaning the reciever is pushing out more than what the amp can handle. As a safty feature to save you from blowing your amp or speakers the amp will shut it self down to minimum as you described. This also occurs when the amp over heats or doesnt have enough ventalation and once again as a safty feature to save your amp it shuts down. My first suggestion is to turn the "Loud ON" mode off on your reciever. As this feature can blow your speakers and can also cause this problem. Also do not use any factory settings on your reciever. It is almost always the bass in any given system that causes this so turn the bass down some on your reciever or on your amp turn it down and then adjust up and down from the reciever. Im sure you probably like the bump bump bump, I do to but your going to have to eiather buy an amp that can handle what your reciever is pushing, or turn it down a bit. You should also check the fuses for not only your amp but for the system under the hood near the battery. My own personal experience I have blown fuses when the system shuts down. Hope this helps
This sounds like the fuses on the logicboard have blown, you will have to take the back cover off to to have a look at the logicboard, the fuses are very small, you will need good soldering skills to replace them. here is a diagram of the logicboard and where the fuses are situated, they are marked F1 and F2:
Could you post back and tell me if the screens come on at all, if they do it might be your battery.
the fuse rating should be printed at the back near the fuse holder itself. If it opens the fuse again and again probably you have a circuit loading problem in the receiver...either one of the amps is failing.
unplug the reciever for at least 15 minutes. then replug in all of your speakers making sure there is no bare wire showing. if the reciever doesnt ower on replace the fuse inside(make sure unplugged from wall)
Activated protection circuitry means that the amplifier is seeing conditions it does not like and is shutting down the power to prevent further damage. Either you have a short in your speaker wires, in your speakers, or a blown amplifier. Disconnect both speakers and turn on the amplifier. Does it still give the error message? If it does, your amp is blown. If it does not, carefully inspect your speaker wires and their connection. Make sure all looks good and reconnect the speakers and try it again. Still get the error message? You likely have a problem in your speaker cabinet(s).
Unit is telling you something is wrong with circuit. LED pilot flashes when malfunction is detected. Power supply shuts unit down to prevent further damage and/or fire. Leave off and seek pro/tech check out
Based on my brief internet research on this issue, after recieving the same error code, it appears to result from a communication issue between the electronic systems of the machine. Personally, I'm returning mine. Too many posts about this error.
