Accurian 6.1 Receiver flashing PROTECTOR

My receiver was fine. I just bought this 2 months ago and only hooked up two smaller Sony bookshelfs as I didn't have a set yet. Yesterday I bough a set of Yamaha 5.1 speakers w/ subwoofer and hooked them up, sounded awesome. It was 6.1 so I said I will hook in a sony (that I had before) into that 6th port. When I did it worked and was fine, I played some music with that newly installed speaker and the receiver kept turning off. Eventually it did not even turn back on at all and now just flashes PROTECTOR when I attempt to turn it on. Any ideas?

    Flashing Protector

  • Anonymous Dec 12, 2008

    Sony receiver has been flashing protector for 10 years. Give it a whack and it usually switches back on but is a real pain.
    I'll have to check if the speakers Ohm rating is the problem - never even thought of it. But I think that this has always been a defective receiver because it has never worked particularly well

I been reading a lot, dont have much experience but this is what I have seen.... if your speakers are 4 ohm then your impedance on these speaker will be too low and should cause the receiver to overheat, this is a natural occurance as the extra power has to go somewhere, in this case the form of heat, this particular receiver is meant for 6 ohm speakers, so i would recoommend either 6 or 8 ohm speaker systems (too high is okay, just not as loud), was it getting really hot before it couldnt turn on anymore? I mean burning hot... if it really got that hot it's possible that some loose solder points may have disconnected, if you fried your board... good luck... cant help ya there... maybe take it to a radioshack?

    yep.... i was right check it out.... this is from consumer reports verbatim


    Is the receiver compatible with your speakers?
    If
    you like to blast music for hours on end, get a receiver rated to
    handle your speakers' impedance. Most receivers are rated for 6-ohm and
    8-ohm speakers. If used with 4-ohm speakers, such a receiver could
    overheat and its protection circuitry would shut it down.

Short circuited some how... cross wire, bad speaker?

Your speakers have the wrong impedance rating. Check the Accurian specs.

Also possible you have short circuited some how... cross wire, bad speaker?

Hi I purchased a sony av amplifier model STR-DB930 on e-bay a few months ago and I am using 3 ohm speakers from my old surround sound system. The output selector on the back of the unit is set to 4 ohms....


The lower number in Impedance specs is not a suggestion. It's a limit. 3 is not between 4 and 8.

If you don't want to buy new speakers, settle for safer low volume levels.

You're going to kill that receiver driving a 3-ohm load. HTS-style speakers aren't reliably re-deployable to other electronics. Perhaps, if you have 4 speakers and they're similar you could wire them in SERIES and present a 6-ohm load to each channel.

Re-engineering the speakers themselves is, well, don't do it. It isn't rocket science but it also isn

How to overcome "error message" 'PROTECTOR' on Accurian 6.1 Sirius-ready surround receiver model 31-5048?


Probably need to replace output transistors and a resistor or two. Could also be one of the 12v regulators.

A job for a tech not for the average do it yourselfer.

Repair cost around $100-120

My sony str-d1o15 says protector


I got this from Sony site, I am doing it to mine now, unplugged it first.
Follow the steps below to troubleshoot if the word PROTECT or PROTECTOR is flashing on the A/V receivers display.
  1. Check the speaker wires and speakers for proper connections.
  2. Reduce the volume level. IMPORTANT: If the receiver is played back at maximum volume level it may enter the protect mode. Maximum volume listening will cause the receiver to run very hot and may drain the output capacitors.
  3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  6. Unplug the AC power cord for about 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.

A 6 flash error indicates a problem with the backlight. Your set is less than a year old and still in warranty, so you should contact Sony and arrange for a service call to get it repaired.
