    I have the same problem. The display on the receiver is flashing "Protect". Surround sound is no longer working. Running the audio directly off the tv now because of it. Wondering if it is worth having receiver repaired or just replacing.

Protect mode with nothing connected indicates an internal problem. Most likely one or more output transistors are shorted. This is a common problem with these and can easily be repaired by a shop for around $35 in parts plus the local labor rate. The output transistors are MN1620 and MP2488 (if memory serves me correctly).

My pioneer vsx815 is in protect mode i disconnected everything but the blue light continues to blink when i plug it in. What can I do to get it out of protect mode?


If you reboot the receiver with nothing connected to it except the power cable and it is still in Protection, there is an internal component that has gone bad.

Try disconnecting your battery, reconnecting it, and resetting your stereo. If that doesn't work, the constant power (yellow wire) or ignition wire (red wire) may have come in contact with ground or isn't properly connected. Make sure everything is connected properly and try resetting your stereo. If it is still flashing "protect", the unit needs servicing Contact JVC Customer Care Center at: 800-252-5722.

When i switch on my samsung HT-Z110 the word hello appears then protect thenit turned off!


Audio receivers have an output protection circuit called "protect mode", this is to protect the receiver from short circuit failures.The speakers and speaker wires are what I inspect thoroughly first, look for bare speaker wires,or bare wires that are touching each other at that point,check speaker wires at the back of the receiver for sloppy connections,etc.If all looks good then try disconnecting all the speakers at the receiver,then turn power on to see if it goes into "protect mode", if it does the the receiver probably has an internal short and will need to be sent in for service,if it doesn't go into "protect mode" then connect one speaker at a time back into the receiver until it does go into "protect mode" then which ever speaker you connected last is the speaker that is shorted(blown) and then you know that speaker is the problem and it will need to be replaced or repaired. Good luck !

Security Code for Protect mode


Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!

Unit goes into protect mode


Not unless you know how to troubleshoot solid state electronics. If you disconnected the speakers and the unit still goes into the protect mode, most likely you have a short in one of the power output stages. Good Luck
