The protect mode is an indication that the unit has detected a problem in the final stage of the amplifier. This can be caused by a shorted wire as indicated by toddg, but one the short occurs, there usually is internal damage that the removal of the external short will not fix. This problem can also occur without crossing the wires because of component failure. If you can post the make and model of the unit in question here, I can give you the most likely defective parts along with their replacement costs.'

This denotes a short in the wiring or a cross of the negative and positive polarity of the speaker wires. Check to make sure the speaker wires are not touching anywhere. This would be the most obvious place of the wire cross. Look for any fray or anything that is touching another cable.

Sony receiver stR se-501 found fuse burned after replaced turned on the flashing massage PROTECT come on . Did I miss anything?


Protect typically means that the fuse blew because something in your receiver went bad. It's now protecting your speakers from that badness. You need to get the receiver fixed or replaced.

My stereo sysytem is a mini stereo: serial number 10200055. It currently says "protect", what is this and how do we return our system to normal operations?


Hi there,

When the word PROTECT appears on this display, this means the unit has detected a critical fault which could potentially cause harm to your stereo system.

The most common cause is a short circuit somewhere - something even as simple as loose speaker wiring could cause a short, triggering the Protect message.

You will need to determine if there is a possible short somewhere, so I recommend you start by firstly turning power OFF, disconnecting all speaker wires, then turn unit back ON.

Operate the stereo (without speakers) and turn volume up:
  • If Protect message appears when turning volume up, then stereo unit itself has an internal fault
  • If no Protect message appears, then suspect the speakers may be causing the issue.
  • Reduce volume and turn unit OFF
Re-connect speakers (ensure the connections are secure), turn unit ON:
  • If turning volume up triggers the Protect message again, there is an issue with the speakers or connections

Hope this helps.....

There is an output load causing the protect to engage, turn unit off and dis-connect the speaker wires from the back of the receiver, this will reset the processor ic. Now power on and turn volume right down, if the word protect stays off it means there is a short in the wires or one or more of the speakers. But if the word protect comes on with the "speakers and wires dis-connected" it indicates a short in one or more audio output ic's and will need a tech to address the extent of damage and cost.

Hi,
f61 is a protection code. it means theres is a fault with audio output ic, usually there is dc on one of the speaker output rails, replacing the audio output ic will usually cure this but check speakers and leads for shorts before reconnecting to the unit.


Thank You

When I turn on my aiwa stereo I hear a clicking noise and it turns off and loses power.


This is an overload protection feature. Check for speaker wires shorted to ground or a blown component.

Usually "protect" mode means it has either

1. Overheated (a thermistor on/near the cooling fins for the audio output transisitors has indicated that the machine is running too hot). This is usually solved by turning the unit off for 30 min.

or

2. Some circuit inside the unit has indicated an error condition, turning your stereo into a doorstop.

Thanks,
Rob
