Does indeed sound like an internal DC fuse problem.
Hope you manage to replace the offending fuse O.K.

Sony amp displays protect and no sound on speakers plz asist.


Turn the volume knob below 3 before turning the unit on. If the volume was turned way up and then the unit turned on it may have blown the speaker protect circuit. It is designed to prevent blowing the speakers. They need to be powered up slowly to prevent tearing the cone.

check the fuse output line in the speaker! or maybe you are in protect mode! checkout the speaker, maybe you have defective speaker, thats why your unit in protect mode, thats why no sounds coming out!

Flashing word "Protector" shows up and the sound stop on my Sony da555es receiver. I have to turn off the unit several times before the sound stays normal.


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. Expect a 60 to 80 dollar repair charge depending on how many parts need to be replaced and what the repair labor rate is in your area.

'protect' blinked and then no sound or display


Disconnect the outside speakers "at the speakers" then turn back on. If the problem persists, disconnect the speakers at the back of the receiver and try again. If the problem stops "at the receiver" check your terminals and make sure no braids are touching each other. If the problem stops when you disconnect at the speaker, chances are good it's a bad voice coil from moisture. Most "outdoor" speakers with a brand name on them have a pretty good warranty. Good speakers have a 10 year warranty and the manufacturer will replace. If you still have an issue, post a comment and I can help you some more

PROTECT DISPLAYED ON RECEIVER


This generally means you've got a short somewhere, and the received is trying to protect itself.

My suggestion is to disconnect all of your speakers at both ends, and reconnect them.

Most times this happens because a speaker wire is lose, and the positive and negative connections are touching each other, causing it to short out.

Onkyo tx-sr602 as soon as i turn receiver on it flashes protect


Does it display any message like "Protect" or something similar? Do you hear a relay click on then off?

Did the amp just not power up one day or did it stop working while you were listening to it? Finally, do you have teenage kids who might have been listening to your receiver and would have "neglected" to tell you that after listening to their music it suddenly stopped working?

It could be an internal fuse but chances are its something that requires a technician to repair (like the output transistors).

Stuck in protect mode


Speakers shorted out, blew a fuse. Replace the unit or (cross your fingers and) open up the box and find the blown fuse.

Trouble shooting a Denon Reciever


I just picked up a non working AVR 900, there are a total of 4 fuses inside the unit: 2 on the protect board, 6.3A and 8A, and 2 in the middle near the front. I was told by Denon the following might reset the microprocessor. 1) unplug unit 2) press and hold tuner and video select on front panel 3) plug in while holding buttons Unit display should flash until you let go of buttons. Unit stays on you should be ok/ goes back to red- service They also said: There are 3 types of protection that will commonly occur with our receivers. This is designed to protect the unit from permanent damage. 1) Thermal Protect = When the unit overheats this will occur, usually if there is not enough air space above and around the unit. There cannot be anything directly on top of the unit and there must be at least 4 inches of airspace above the unit. 2) Overload Protect = Most commonly occurs when a strand or more of copper speaker wire is not securely connected to the speaker terminal and is touching the chassis of the receiver. If the volume is turned higher than 85% this may also occur. If you need to turn the volume higher than this point to get the level you want, you need a more powerful amp. 3) DC Protect = When an amplifier fails this will occur. This will protect dc current from damaging the speakers. When this happens the unit will need to be serviced. I had a bad 6.3A fuse ? I replaced it and tried to reset. The microprocessor would not reset. I had the exact same results you had. The chip on the back side of the front IC board was smoking. Before I attempted the reset I asked Denon if it was worth sending in for repair. The answer was "NO" BC
