Protet mode is a special diagnostic mode that starts when a fault is detected.
When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.
Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.
Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.
If you do all the above and still get Protect, then there is a real fault.
In that case the unit may be disassembled and tested to find the fault.
If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

Hiya, not sure if i remember correctly but try reset it. First disconnect the speakers (make sure error isnt there)
When it is ON, press and hold the power button for about 4 seconds. It should then ask reset, clear or something and press enter. When its finished, try it again. If ok, reconnect speakers. If it happens with speakers, there is a problem. If it doesnt work and goes straight back to protect, then there is an internal fault (if i have the reset procedure correct)
Best of luck
