Protect keep showing in screen

I turn on the receiver then the display says protect. It worked great for about a year and now lately if I turn the volume up it does it again. The manual says to check the speaker connections, I did, they are all ok. Please HELP!

Theres a few things that can cause that. The protection on the reciver means that a wire is crossing somewhere or it can mean the unit is over heating. replace wires and find you 2 speakers to just test to see if you have a bad coil in your speakers. Replace the wires even if they seem to look ok they might not be. If that fails, the unit could have a problem causing grounding or over heating.

All display lights are illuminated but device doesnt work


Do you hear the speaker protection relay click after about 10 seconds when you turn the receiver on? Does the display show PROTECTION on the display? These conditions indicate a bad channel that will keep the receiver from functioning but you still have lights. Steve

DVD system shuts down during DVD play with various parts of shows


I think this is the answer you are looking for.

Let me know if you need more help.

Knowledge Article C337191 Error: The message PROTECT or UNPLUG shows in the display.
Follow this procedure to troubleshoot when a PROTECT or UNPLUG error is displayed.
IMPORTANT: The top of the receiver must have proper ventilation to keep from over heating.
  1. Reduce the volume level.
  2. NOTE: If the receiver is played at the maximum volume level it may enter the PROTECT mode. Maximum volume listening will cause the receiver to run hot and drain the output capacitors.
  3. If both the A and B speakers are being powered by the receiver at the same time, turn off the surround sound option.
  4. If protect occurs only when using a DVD player, the sampling frequency may be set too high.
  5. NOTE: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the user manual for specific information.
  6. Ensure the speaker wiring is not damaged and is properley connected to the back of the receiver and speakers.
  7. If the issue is still unresolved after completing all of the troubleshooting steps, service may be required.

I have a Sony STR-DE 597 reciever. I have been using it fine for a few years with no problems and it sounded great. I turn the unit on recently and a message was displayed on the unit that said PROTECT....


Protect will usually show up if the receiver was turned up too loud to the point where the speakers will crackle, the receiver will switch to protect to not damage anything. Unplug it for about 30 seconds and check all the audio wiring in the back to make sure everything is plugged in good and tight and no loose cables or stray pieces of copper audio wire and plug it back in.

This amp wwhen turned on, dosplays 'PROTECTOR' on teh display, what is this telling me?


Disconnect all the speakers and unplug it for 5 minutes. Then turn it back on without any speakers plugged in. If it doesn't say protector, then you either have a shorted out speaker or wire. The amp is in protection mode which is designed to keep it from burning up. If it still says protection, then it will need to be repaired as it is too late.

GARMIN NUVI 850 AM SCREEN KEEPS LOCKING UP PROBLEM APPEARS TO HAPPEN AFTER ABOUT 15 SECONDS OF BEING TURNED ON NO MATTER WHAT SCREEN IS BEING DISPLAYED. YOU CAN MOVE THE SLIDE SWITCH SWITCH TO THE LOCK...


Garmin used to have good products, but seem to be slipping badly lately. I have an 850 and it does the same thing. I have downloaded all new software that is suppose to fix it, but it is still happening. Great they have a removable battery now. Little did we know that it is removable so we can reboot the piece of junk!

Try the latest software and keep youe dingers crossed.

NO GUI displayed


I had a similar problem with my Denon 3808 after it had the protection circuit tripped. First all I would get is a blue screen with sound, then after powering the unit off I got the display back, but all of the on screen GUI menus were gone. I could tell that the menu button worked because display located physically on the recever worked. I reset/rebooted the system (follow the directions in manual) and everything came back. Be aware by resetting the system any customization you have done will be lost. Hope that helps

I have Panasonic SC-AK750 Mini System and of late it keeps showing F61 on the screen before it switches off. do you know what it is


The F61 indicates protect mode. This means that a problem was detected inside and the unit shuts down to prevent further damage. This is usually the output amp pac or the regulator IC. The amp is attached to the heat sink in the rear of hte unit and should be marked RSNxxx.
