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!

Re: protect keep showing in screen

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

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.

What does the word "Protect" mean in the display? My receiver AG-D9100 works great and then quits and the word PROTECT comes up in the display. If I turn it off it usually starts right back up ok...for...

Something is shorting out and tripping a safety feature that protects the amplifier from damage.

try a few simple steps to see if the problem is internal or external.

First make sure that none of the speaker terminals have any loose strands of wire that could be grounding out the terminal and that no wires from the red terminals are touching the component or the black terminals / wires.

secondly disconnect all but one speaker test it to see if t causes the amp to go into protect do so for the other speakers until one trips the protect mode. If one of the speakers is tripping the protect mode it could be a damaged / blown component.

just for fun make sure your speakers are 8 ohms this can be found on the manufacturers website or in your manual. Its rare but some speakers are 4 ohm and they can cause amplifier issues such as tripping a protect mode.

You may have to evaluate the "value" of the receiver and determine if its worth repairing. Many shops will charge a "diagnostic" fee which may be $40 to $80 and remember that parts and an hours labor may not make good financial sense especially if you are talking a unit that is 5+ years old.

Hope this helps

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.

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.

Overload on Technics SA-AX710 Receiver

first of all, check all the capacitors. Other than that, it needs a repair guy to have a poke about inside it with a screwdriver. Has anything happened to it lately that could have upset it a little bit? such as a powercut or had anything done to the plug? (e.g. change of fuse, and put in one that was a different rating) And is it plugged into a surge protection socket, or a plain old fashioned electrical socket?
