Re: PROTECT thats all it says when I turn on my recevier....

Yes thats an easy problem to fix. when it says protect, that means two of the leads on the speaker wire are touching eachother. that means the positive and negative wires on it either going to the receiver or the end gong to the speakers. look at all of them. then if they were touching. take them away from touching and then turn your receiver off. then it will come back all ready to use. but if thats not the case i dont know what other reason it will be doing that. but anyways thats my theory of why its doing that!

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.

When i turn it on it says protect and it turns off after that


Usually a protect fault will indicate a bad transistor in the amplification section. I suspect that the control circuit is sensing a fluctuation in the power supply and going in to protect mode. (assuming that the protect circuit itself is working properly) If a voltage is too high the unit will go in to protect mode to prevent damage to the speakers and the rest of the unit. I would take the unit in to a local repair shop and get a estimate of repair charges.

Hope this helps.....

My kenwood 107VR keeps turning off on its own, after about 3 secs it shuts off and the light blinks.

If you are sure your speakers are good. This unit has a protect circuit keeping the unit from turning on. This recevier uses an ic instead of output transistors. A ic incorperates transistors,resistors,capactors in one assembly for size and costs. There is a number right on the front of the ic ,you can go on-line to buy the ic is is fairly easy to put in as long as you can desolder and solder in.

My reciever is blinkning 'protect' after being turned on. It starts up as normal but after the initial start it starts flashing 'protect' and after it starts flashing I can not do anything but turn it off....

It shows protect when it senses a problem with the output wires shorted or some internal fault. Try disconnecting all the speaker wires and power up again. If it still shows protect, then the fault is internal.

When swicth on, it goes out after writing protect, can i do anything?

It goes into protect mode when it senses something wrong. First check the speaker wires for shorts or diconnect them as a test. Turn it on, if still in protect mode, the problem is internal and needs to be looked at by a tech/repair shop.

Monitor show " Protect " can't do anything.

Protect is an indication that one of the output amplifiers is shorted. The unit turns itself off to avoid burning more components. I'd recommend taking it in to a repair facility for replacement of the blown output amp.

Just check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Rewire if necessary..
Are you using banana plugs for connecting speaker or just directly. Some times even a little tiny frayed speaker cable touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit.

If everything else seems all right and still your receiver goes into protect mode or wont tun on then it possible that there are bad connections on the main board that sets in. How old is your system? if its still underr warranty then you should contact Yamaha immidiately.

If the reciever is old and if you can solder, you should be able to repair it yourself. This should be a simple repair that will not require parts. If not, then a local service center will change the local labor rate.
Let me know if I can be of any further help. Please do rate this solution and thanks for using FixYa!

I have a Harman Kardon AVR 235 Receiver that go's into Protect

To avoid making the avr go into protect mode when you power up your Hafler 4000 that is connected in the avr's pre-out, you must power up the set up in the correct sequence.

1. Turn off your avr
2. Connect Hafler 4000 to the avr's pre-out it it is not yet connected
3. Turn on your Hafler 4000. The avr will not go into protect mode becasue of the transients from the Hafler because it is still not powered on.
4. Turn on you avr. There should be no more transients from the Hafler at this stage unless it is not functioning correctly, so the avr shouldno longer go into protect mode.

Sony STR-DE445 protect displayed

It sounds like a bad solder connection. It just needs to be soldered up, if you take it into a shop just tell them it doesn't need any new parts, it just needs to be soldered up.

Or, if you can solder it yourself, or know someone that can, that would be much easier.
