Awia Stereo shuts off when volume is at 25+


That's the system's way of protecting itself from a burnout *(like a fuse). If you are not using the system's recommended speakers, this will continue to happen.
So, I'd highly recommend that you do some research, look for the manual, and get the correct speaker ratings. You might have to custom build your boxes, but, it will sure stop that problem.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

Just purchased the Sony DAV-HDX285 and hooked everything up correctly. The only thing I added more speaker wire. When I turned the system on the Protector light Push Power came on. I returned the system...


Protection is usually a speaker wire shorted somewhere. Does that suggest something? Did the two units function okay BEFORE you modified them? Or afte ryou disconenct the speakers?

Look at inside at capacitor and fuse but they seem ok. again once i turn it on, it would automatically shuts off after a second.


When a system shuts down after a few seconds it is the self protect circuit shutting down power to the outputs to prevent (further) damage. It may be caused by frayed speaker wires, bad speaker voice coils, or blown output transistors. First, turn off power and remove all speaker wires from the receiver. Turn it back on and see if the problem remains. If it works OK, inspect each speaker wire at both ends for loose strands and correct these. Then, hook up your speakers one at a time until the problem reappears. That speaker or its' wiring is your problem. For safety's sake. turn the receiver off before connecting each speaker. An accidental short of the output terminals can be disastrous (and expensive).

I have a Denon receiver, had it for a couple years now and has worked perfectly. Last week I was watching a movie and all of a sudden my receiver shut off and it blinked a red ring of death. I let it rest...


Did you recently move any speakers around or any items near the speaker wire connections?
It sounds like you may have a speaker wire shorting which is causing the receiver to go into "auto protect" mode. Check all of the speaker wire connections on the back of the receiver and at all of the speakers to make sure the wires are not touching or close enough to possibly touch.

Shuts down by itself


If there are no speakers connected and you still get the protection message, there is a problem internally. Exchange the unit while you can. The typical parts required to fix this problem will be over $75 US.

the message you are getting is "amp guard". This is the mesage it will display when a short in a speaker wire or speaker with low impedence is hooked to the internal amp and sends it into protect mode, shutting down the amplifier section while the rest of the unit continues to work.
Check your Factory speaker locations for blown speakers or bare wires to metal.

Protection light


take the amp out and hookit up to the car battery and let it charge then unplug it do this a couple of times then rehook it to the cars audio system it sounds like your amp may be locked..

also check your speaker wires from amp to speaker box then from the back of the box to the speaker inside the box you may have a short..

thats where i would start.. hope this helps

Hi,

Take every single cable out of the unit, now power on the unit.

If the power protection still shows then there is an internal fault, usually a short or a component defect.

If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.

Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.

Cheers

No sound


Blinking LEDs indicate a problem with outputs. Or speaker impedences are too low (below 4 Ohm)
