This more than likely means that you have a blown fuse. Go to an electronic store and replace the fuses. Make sure you get the exact same sizes and types that you had before.

Hi ,
If you have a knowledge in disoldering and
soldering technique, I would advice you to pull-out this part and then try the
unit. If the "Amp Grd" error code is gone then you must replaced this
IC with a new one to back your unit in normal operation again.
"Protect" is an error code for short and overload. Once the power applied to the unit and shorts sensed by the processor, the unit will
automatically turned to "protect" to avoid further damaged to other
parts. Most shorts is in the supply voltage (B+, Vcc) line and most common
caused is the sound output IC (mounted in heat sink). This part is responsible
for amplifying the audio from the pre-amplifier stage and will feed to your
speakers.
Before that, try to isolate first the speakers, if you have a shorted one, same symptoms will be encounter. Disconnect all the speakers from the unit and turned it on naked. If the symptoms is gone, then check for shorted speakers.
Hope I helped you.
Have a nice day!
