    My receiver has the same problem. I turn it on and works for a couple of minutes, then "POP" and the protector signal comes on. Is it worth it to fix it?

    im having almost the same problem. the protector light comes on, but only one speaker turns on at a time. i thought at first it was maybe a blown speaker, but i wanted to make sure. so i changed speaker cables, and changed to peakers setting "B", both speakers work 1 at a time but together i get that message.

    I too have heard the POP and smelled a smoky smell. The PROTECTED message was showing. Powered down and now I get no sound, even though everything seems to be powered up ok.

    It would be nice to know the solution.
    Seems strange that so many are happneing at the same time.

I checked the speaker connections and found there was the tiniest strand shorting out. Re-twisting wires, re-interting and ensuring no short fixed the 'protect' problem for me.

This message indicates that a problem was detected in the amp. In order to prevent any further damage to the amp or the speakers, the outputs are turned off. Does the receiver show this at all times now?

Most of the time, when the receiver is powered up, and after a few seconds, there will be a loud hum and POP from the speakers, the PROTECTOR display will flash. This does not happen every time the unit...


Hi Ted,

First of all, thank you for posting your question here at Fixya.com.

"Protector/Protect" is an error code for out-of-regulation condition either on the power supply board and/or on the Sound output circuitry.
I've encountered this kind of symptoms not only on Sony home audio sound system but in almost known brands and the faulty parts are the same >>>> smoothing/filter electrolytic capacitor.
This is very common most especially on older unit because the capacitor begin to dried up resulting to voltage/audio out-of-regulation. In the first stage of fault, warm up will make itself stable but it will get worst as times goes by.
This is fixable and not a costly repair because this is one of the cheapest part on the board and widely available at electronics supply and online. You must have a test instrument (capacitor checker/tester) because not all capacitor that are look physically fine is in good condition, capacitor checker will reveal its condition.
Watch the video below for more info regarding electrolytic capacitor.

For efficient troubleshooting, you must know which section/board are going to repair. In your case, AC board, DC board, REAR-AMP board, and the mainboard(Sound output circuitry) are going to troubleshoot.

> Check or replaced C905 on AC board - this board is where the AC power cord's directly connected.
> Check or replaced C801, C803, C804, C807, C808, C809 on DC board - this board is where the two larges electrolytic capacitor is located.
> Check all electrolytic capacitor on REAR AMP board most especially in front of IC701(UPC2581V)
> Check the electrolytic capacitor in front and at the back of IC501 and IC601 (both UPC2581V) on the mainboard.

Note : IC501, IC601, IC701 are mounted on aluminum heat sink. Concentrate first on AC and DC board.

Once you've isolated the faulty electrolytic capacitor, your unit will back to normal again.

Hope I helped you.
Rating and feedback are highly appreciated.
Have a nice day! Good luck and take care!

Kind Regards,

The main source for replacement belts is the "PRB Line." You can Google this and it will lead you to many suppliers that carry belts. Russell Industries owns the PRB line:

but you can't buy directly from them. You will find much of their catalog here:

you have speaker wires that are shorting out. unhook all the wires and ohm them out. Find out which one is shorting. I've had this problem before. It's fine until you turn it up, Then the receiver turns off and goes into protect mode. It's just a short in the wiring,.

hi yes you can do this press AUD button near the on/off/volume control momentarily to step through the following audio adjustment options volume, bass,treble, balance (left to right) and fader (front to back). when the desired option appears in the display, rotate the volume control knob to adjust that audio feature. When no adjustments have been made for three seconds, the unit will resume normal operation. so you can fade the speakers to however you want them...hope this helps

Error code - protector


Try disconnecting all the speakers from the back and turn the unit back on. If the "protector" display goes away, turn the unit back off and reconnect one speaker. Turn it back on and check for "protector". Repeat.

If you find that one of the speakers causes "protector" to appear, you either have a bad speaker cable or bad speaker. Try swapping each of those out to see what happens.

Problem getting the best surround sound when watching a dvd


THE BEST SOUND IS WHAT SOUNDS BEST TO YOU, HOWEVER DO THIS:
1, USING THE SETUP MIC CONFIGURE YOUR DENON, PAGE 8 OF THE MANUAL. NEXT
2. RAISE THE REAR SPKR LEVELS, PAGE 46,47. NEXT
3. WHEN LISTENING TO AUDIO CD OR RADIO TRY THE 5 CH STEREO DSP MODE.
4. WHEN WATCHING A DVD USE DSP DOLBY PROLOGIC OR TRY 5CH STEREO IF THE MOVIE IS MOSTLY TALKING.
5, TRY 5CH STEREO WHEN WATCHING PROGRAMS WITH MOSTLY TALKING

No audio


Go to amp set up menu and make sure it knows the cables you are useing,ie-if the dvd is wired with coax for sound go to input set up and tell the amp you are useing this type of cable.If this is not the problem and the sound is going off one device at a time your amp needs to go back to your dealer.
hope this helps.

Audio problems


Hi, I just started having the same problems with my Onkyo TX-DS575. I have to play with the DSP buttons...the A/B speaker button...and now it has gotten to the point where my family and I lift the receiver up in the front, and slam it back down on the shelf and then hit the DSP buttons again and eventually we get some sound. This unit was already fixed once by Onkyo right after the 2 year warranty ran out for a similar problem. They returned it working...but scratched. This is the second Onkyo receiver that has died an early death within 15 years. I love Onkyo's styling, ease of use and sound, but I found the best way to solve this was by purchasing the Yamaha RX-V861 this week. I am done with Onkyo. Scotty D, Middletown, NJ
