What does the protector error on a Sony receiver mean?
The Protector error on Sony amplifiers and home theater receivers means there is an internal speaker issue or connection issue that may soon damage the receiver. To protect its components, the receiver automatically goes into protect or protector mode, flashing the error in the receiver's display.
What does it mean when your stereo says protect?
Accordingly, what does it mean when your stereo Says protect? Your stereo receiver is going into protection mode because the receiver has an internal short, a speaker is bad or the speaker wiring has a problem, such as incorrect wire gauge or bad connections.
Why does the Protect message keep appearing on my Philips TV?
However if the protect message keeps appearing all the time and without the speakers attached, then it is likely that there has been permanent damage to the internal components, and the unit will require repair.
What is the purpose of the protect error on a speaker?
The purpose of the protect error is to protect the amplifier components from damage should a short circuit occur. The most common form of short is usually user error when they short the speaker terminals, or overload it by attaching too many speakers.

What is Sony Protect or Protector mode?
When your Sony AV receiver enters this mode, you will see either the word ‘Protect’ or ‘Protector’ appear. Protect/protector mode is activated to prevent damages to your receiver’s internal components such as the power amps, circuits, transistors, etc.
Sony Receiver is Overloaded
If your Sony AV receiver is overloaded to the point of clipping, it will trigger the Sony protect mode. This usually happens when you turn up the volume too high during a music/movie playback as it draws more power from the amps.
Speaker Wires are touching
You should check for loose speaker wires or wire strands that are touching each other, touching other wires, touching the back of your Sony receiver, and the speakers themselves. These situations may short the receiver, and activate the protector mode. Either due to wear and tear or by accident, strands of speaker wires may be exposed.
Disconnecting all Speakers
This is another way to check if a specific speaker and/or speaker wire/cable is causing the issue. Turn off your Sony receiver, then proceed to remove all speaker wires/cables from your receiver. Turn it back on, and if the problem stops, that means one or more of your speakers or wires is triggering the Sony protect/protector mode.
Speakers Impedance
You must match your speakers’ impedance with the impedance of your Sony receiver that is designed to drive. If not, your receiver will activate protect mode. Your speakers may get damaged as well due to incorrect impedance.
Reset the Sony AV Receiver
Turn off the receiver and turn it back on while holding the power button for roughly 10 seconds. A screen will appear prompting something like press enter to clear all and you’ll just need to press ‘enter’ on the remote control. Your Sony receiver will default back to factory settings and all your previous configurations will be gone.
Problems with Specific Models
There is a slight possibility that it could be an issue with your receiver model only or your batch. You can check online to confirm this and if it is true, there’s maybe a firmware update that can solve this issue.
What happens if Q703 goes short?
If we look at one side of the push-pull stage, we see that if Q703 goes short between its collector and emitter junctions, the voltage rail would flow through the speaker and ground, however, there is R716 in the path, which will go open.
What happens when transistors go short?
When the transistors go short between their collector-emitter junctions, it creates a path from the positive voltage rail to ground -- or negative rail to ground, in a split voltage system -- and the only resistor in this path is this non-flammable resistor, which goes open.
What is the purpose of protect error?
The purpose of the protect error is to protect the amplifier components from damage should a short circuit occur. The most common form of short is usually user error when they short the speaker terminals, or overload it by attaching too many speakers.
What is the protection mechanism on an amplifier?
The protection mechanism usually places the amplifier into protect mode when it detects a short, and during this time it prevents power to the amplifier circuitry, thereby preventing harm to the speakers and expensive amplifier components.
What is the difference between MP1620 and MN2488?
The MP1620 is a PNP type , whilst the MN2488 is its complimentary NPN transistor. These are hardy transistors with collector current (Ic) rated at 10-A. It would require a hard short across the speaker terminals in order to damage them.
What happens if the Protect message goes away?
However if the protect message keeps appearing all the time and without the speakers attached, then it is likely that there has been permanent damage to the internal components, and the unit will require repair.
