Fan protector message on reciever

check power supply and drive circuits

Turning it on the onlything it says is Welcome Protector and does nothing else

Is the message "Protector" or "Protected"? Several models will say Protected if there is a voltage/power issue with either the unit or the speakers attached.

This can be triggered by a short in a wire to the speakers or to the unit itself or a blown fuse inside the unit. Unplug the receiver from the incoming power from both the receiver and the outlet, if possible. (This applies if it is a free-standing unit; units in cars are different.) Then unplug the speaker connections. Reconnect the AC power and attempt to turn on. Does the error persist? If it has been resolved, plug in the speakers one by one. If you get the message as you plug in the speakers, check the wires for a short. Check if your speakers are drawing more power than the receiver is capable of handling. (This only applies if the speakers are directly connected to the receiver.)

If the message occurs before you plug in the speakers, check for a problem with the ground as well as for a short in the rest of the power connections on the unit. If there is no obvious damage, then if the unit is still under warranty, consult the manufacturer for a warranty repair. Otherwise you'll need to open the unit and check the circuitry. (Replacing the fuse may work. However it will not resolve the problem if there is another problem that is causing the fuse to blow.)

I hope this helps. Please add a comment with the make/model and specifics of the receiver for more information.

My sony str-de335 receiver is in protect mode whats wrong what should i do?

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance 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 device cant open the disc tray please advise me on what to do

Electronics Corporation sells inexpensive DVD players. The DVD players, however, often exhibit problems due to their manufacture and way that they work, which must be dealt with during the course of the player's life. Knowing what these problems are beforehand can aid in resolving difficulties when using the DVD player. In some cases, it can help eliminate the problem before it can become catastrophic

The disc door is not properly closed if the Disc player display shows an "Open" error message. Check that there are no gaps in the door and use the remote to open the disc door. If it will not open, unplug the Disc player and gently pull out the disc door and then push it in. Plug the Disc player back into the AC socket.

If the DVD has not been inserted properly into the disc tray, a "No Disc" error message will come up on the display. Eject the disc and lightly flick off dust using the edge of a lintless cloth. Inspect the disc for damage. Insert it carefully again into the disc tray and use the remote to close the disc door.

Because the Disk player is inexpensive, the power supply is not of the highest quality. Having a surge protector to plug into the Disc player will help to keep the power supply from being damaged over the course of its lifetime.

Have a nice day

Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts. If it cuts out, it needs service. If you need detailed troubleshooting help on this after testing receiver without speakers connected and it passes, post a comment and I can walk you thru it. Hope this helps.

Keep getting message protector

if all connections and speakers seem ok the problem is internal witch can go from blown power supply to shorted output devices and everything in between , and as always look for repair shop in your area, do not attempt to do it yourself, firehazard and electric shock are the things we all want to avoid ;)

MySony str-da5000es is showing error code 11 and shut off by itself after few seconds.check and disconnect all speakers, unplugged power from wall and still showing error 11. am missing something in here...

error code 11 (protector) - According to the manual, 11/PROTECTOR means, "Irregular current is output from the speakers. Turn of the receiver, check the speaker connection and turn on the power again." Most likely, a strand of speaker wire is shorted to the chassis at one of the speaker terminals.
Hope this helps !

Error code - protector

Try disconnecting all the speakers from the back and turn the unit back on. If the "protector" display goes away, turn the unit back off and reconnect one speaker. Turn it back on and check for "protector". Repeat.

If you find that one of the speakers causes "protector" to appear, you either have a bad speaker cable or bad speaker. Try swapping each of those out to see what happens.
