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.

The unit is not waiting for a reset or a command. The unit is in
standby because an internal fault had been detected, and the controller
circuit started in protect mode.
Protect 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. the PSU will be
forced to standby, and the unit does not wake up until the fault is
fixed.
Check all wiring and connectors, a contact in speakers wiring or video connection cable can start 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

If that was the problem, unit will start normally when plugging back power cable.
If you do all the above and still have the unit in forced standby, then there is an internal fault.
In that case the unit must be disassembled and tested to find the fault.

Better ringing the number in the manual first.

I have a Sony AV receiver, an STR DG-600. The receiver has recently started to experience short, split second interruptions in every mode. When it plays, it will play, then stop playing for a split second, then start playing again. Can anyone help?
