SONY STR-DE445 UNLOCK CODE


Follow the steps below to troubleshoot if the word PROTECT or PROTECTOR is flashing on the A/V receivers display.

  1. Check the speaker wires and speakers for proper connections.
  2. Reduce the volume level. IMPORTANT: If the receiver is played back at maximum volume level it may enter the protect mode. Maximum volume listening will cause the receiver to run very hot and may drain the output capacitors.
  3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  6. Unplug the AC power cord for about 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required.

When playing dvd or or on video 3 playing a directv movie. Receiver keeps shutting off and the screen says protect. Seems to do it when the movie scene gets loud.


check your wires if there not touching behind the speakers and receiver. when it says protect this means something is shorting out or crossing over. one other thing it may be is if a speaker is starting to go bad. (please rate)

It says protector mode what does that mean


If PROTECT , PROTECTOR or a P is flashing in the display of the A/V receiver, there may be an incorrect connection or an improper setting. Try following these steps to resolve this issue:


NOTE: Because each of these steps represents a possible solution to this issue, check the A/V receiver status after completing each step.
  1. Check the speakers and speaker wires for proper connections.
  2. Reduce the volume level. IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.
  3. If applicable to your model, disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the A/V receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some A/V receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  6. Unplug the AC power cord for approximately 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required.

On my Sony Surround Sound tuner, if I raise the volume up to a certain level (not that loud), I get a flashing sign ''protect'' and the sound to the speakers are cut.


Sony has protection in these receivers for two main reasons.

1 - Checking for DC voltages on the outputs to speakers. Not your particular problem.

2 - Excessive current being drawn from receiver on one or more of the speakers.

Number 2 should be your starting point in finding a solution. Put the volume level on Medium - 35 to 40 on the front panel. Now listen to all you speakers in turn. Any scratching noise will indicate a defective speaker. Remove this speaker from the receiver output and check again if the set goes into protection on high volume.

If you could not find any strange noises on the speakers, remove them one by one and test the set on high volume.

Never - attempt to disengage the protection on this amplifier. The only times we have found the amplifier to be defective with this protection error, it has done so no matter the volume level. Therefore I believe your problem to be a speaker or speakers.

Good luck!

Vollume trouble


the system protect is usually displayed when a condition of short or shorting is occurring in the speaker wiring or the voice coil of any of your speakers.... thte circuit of you reciever is trying to protect itself and you from a very costly repair,,,so it you have another set of speakers try to use them and see if the condition still exists and if it does the problem is in the output section of the receiver,,,and if the protect no longer exists you have fixed your problem,,,good luck
