The protection mode is there for a reason...the main one being to protect your speakers in the event that there is an issue with the amplifier. Bypassing the protection can easily result in the destruction of your speakers and the unit itself. Your receiver needs to be examined by a real live technician.

SOURCE: stuck in protect mode

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.

SOURCE: Sony STR DB-930 Receiver jumping into protector mode

I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.

Re Assembled unit and it worked OK.

I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.

Thanks for the technical help, sure solved my problem.

Regards

Darryl.

SOURCE: my sony receiver is stuck in protect

Hi, I had this very problem with my Sony 5.1 home theatre amp - after a few seconds it would go into 'protect' mode and would not play sounds. Having checked all the usual causes such as wires/ shorts etc I took the outer case off revealing the 'workings' and just tightened up every cross head screw I could find. Since then it has been perfect. Might be that I had a bad earth???

I have a Harman kardon 1700Avr that is stuck in protect mode, Is there anyway to bypass or reset it? Thanks....


It's in the protect mode because of a component failure inside. It needs to be repaired to get out of the protect mode.

if you disconnected everything and it still goes into protect, the most likely there is a damaged amp channel that will need to be repaired.

Protect mode


I didn't see any mention of it in the STR-D565 manual, but on many other Sony models the "Protect" indicates a short in a speaker wire.
