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

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

My STR-DE925 reciever isn't giving me any sound. When i turn it on everything works like normal, kicks on, and there is a click; but after a few seconds the display switches from whatever input it was on...


check speaker connections.sounds like the system is trying to stop some thing more serious happening by shutting itself down.a pain yes but saves blowing something up.if no luck,then definately send in for repair

If your going to buy an antenna you could do some research at cccrane.com. They might be able to help you with the other problem too.

Protector


It shows protector because the unit detects a short in the amp section of the unit. You will need to trouble shoot the amplifier section and replace the bad parts. If you have no solid state repair experience, my best advice would be to have a pro take a look at it for you. Good luck

Manually tuning the reciever


you should be able to tune in manually.
press tune
press fm or am
press d. tuning
enter the frequency of the station 4 or 5 digits ie 9370 or 10450

another thing to look into would be getting a yagi fm antenna, they are directional and although you may have to rotate it for best results, they work great.
