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

The display shows PROTECTOR and there is no sound


This means that the amp has detected a short, or low impedence and has shut down. check all the speakers for bad connections and shorts.

Make sure none of the speaker wires are touching each other. If they are, it will short out the stereo which triggers protection mode and cuts out all of the sound.

My str3000es when turn on the screen show STREAM UNLOCK and PROTECTOR THEN turn off by itself


Check all of your speaker connections at both ends for looseness or any stray wire strands. If they make contact with the chassis, this can and often does cause the electrical short that is making the receiver go in to protect mode. The protect mode prevents electrical damage to the amplifier.

Once you have all of the above verified and fixed, try to power it on again.

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

I keep getting a Protector reding on my screen and it will not let me do anything. What do I do to fix this?


Try disconnecting everything (speakers cables, signal cables, all other units) except the power cord, then turn the unit on, if the protector message persists, then the fault is in the reciever.

If this is the case, you should check the speaker and signal connectors for any damage, shorts or loose solder contacts, also check the unit for any shorted or broken wires, loose wire connections, bad solder contacts on connector pins, bad solder contacts on ANY other components (give some extra attention to the components that tend to warm up while they operate, like main power amp transistors / ICs, voltage regulators, power resistors, diodes, also coils, capacitors, etc). Any loose solder connections should be resoldered.

If there's no message when you've disconnected the outside equipment, you have either a bad speaker, a bad speaker cable, a bad signal interconnection cable, or a fault in any of the units that were connected to the reciever. You can find which one is the cause by turning the reciever off, then connecting one cable or unit, turning the reciever on again, see if there's a message, if there's none, turn it off again, connect the next unit / cable and so on, until you get the protector message. The cable or unit that will make the message appear is most probably the cause for the trouble (there might be loose solder connections on other units' cable connectors or other components). When you plug and unplug the cables many times, with time this will loosen the solder connection on the pins inside the unit, so these need to be resoldered.

Hope you can find out what it is.

The idicator on my sony srt db930 reciever protector turn on.


There are a number of problem detection circuits inside the unit that will shut it down to prevent further damage. The most common cause of this is either crossed speaker wires or internally shorted output transistors. Try removing the speaker wires completely. If the unit still starts with the protect message, then the problem is internal to the unit. For these models, the output transistors usually cost in the $8-$15 range each and are replaced in complimentary pairs. Without taking internal measurements, I can not state that this is your exact problem, but it is the most common. Add in your local labor rate to get your approximate repair cost. Dan
