TX-DS555 Audio Video Control Receiver

When I turn my receiver on it powers up and after approximately 30 seconds it will show protect and then turn off. Is there something I need to do to make it function?

When i turned my harman/kardon avr65 it flashes protect on the screen what could b the problem


In most cases this involves the audio output transistors or ic's in the receiver, the auto protector is sensing a short in the load. But lets do a couple of checks, turn down volume all the way, power off, remove all speaker wires from the back, now turn receiver on to see if protect comes back, if no! check wiring for any shorts and connect speakers one at a time leaving the volume down, if you find one that triggers the problem you have found the culprit, on the other hand if protection is triggered with all loads removed this would be a good time to get a technician to assess the situation.

Acoustic Research Model AW871 wireless sterio speakers


Your connection between the AR transmitter and the ONKYO receiver sounds solid. I'd guess it's the wireless speakers that are the wrong point, or at least that's what I'd look at first. Doing a bit of research, I noticed a couple minor points. First, these seem prone to RF interference from other RF devices. Have to tried switching channels on them? Second, someone reported theirs would not work properly unless the speakers were turned on just before the transmitter, and turned off shortly after the transmitter. Apparently you have to hold the button on the front in for 5 seconds to turn the speakers on or off. I know that's rather basic, but it's been a few days and no one else has responded, so I figured we should start somewhere.

My audio/video receiver which was playing well but all of a sudden turned off as I was attaching a speaker wire to it. Now it will only stay on for a few seconds before 'clicking' off. Can you...


I guess you missed the part where it says to power everything off while making connections.

It sounds like you shorted the amplifier. Try it one moretime without any speaker cables attached. Then take it in to a Tech.

Will i be able to swap the original speakers of the J520 with a pair of Sony SS-B1000, without causing damage to the new speakers? the Sony SS-B1000 has an Impedance of 8 ohms, and peak power of 120 watts.


Hi, As long as you like the way the speakers sound there is really no reason you cant use whatever speakers you want. To find out the approximate wattage of the stereo you are using look on the rear of the unit and you will find a tag that has " SPECIFICATIONS " on it. There you will see perhaps the a.m. and f.m. frequencies it's capable of receiving also there should be numbers saying something like" 100-240vac or 100-240v~ 50-60hz 1.2amp or 120watts.( if power is listed in amps only-1 amp's equivalent to about a hundred watts)Dividing the wattage by 3 will give you an approximate power out put. Example if your stereo draws 120 watts worth of 110 from the wall it will put out approximately 40 watts to each speaker. Changing from OEM speakers is all right as long as you don't try to hook up some 150 watt peak speaker to a stereo capable of just, say, 10 watts per channel. Doing this will eventually cause damage to the amplifier, not to mention causing about 30 percent total harmonic distortion-which take my word for you will know if you ever hear it! So long story short-use what you wish, just be careful not to overload the receiver-if the speakers are a bit to powerful for receiver you can lessen distortion by turning down the " BASS" as that takes the most power in a speaker. Thanks for choosing FixYa, I hope this helped-good luck, Prodzilla

From the link...


PROTECT, PROTECTOR or the letter P is flashing in the display of the Audio/Video (A/V) receiver. Solution
sp.gif sp.gif If PROTECT , PROTECTOR or a P is flashing in the display of the A/V receiver, there may be an incorrect connection or an improper setting. Try following these steps to resolve this issue:
IMPORTANT: If model-specific information is needed to complete any of these steps, refer to the instructions supplied with the product. Manuals are available online through the Manuals/Specs/Warranty link on this page.
NOTE: Because each of these steps represents a possible solution to this issue, check the A/V receiver status after completing each step.

  1. Check the speakers and speaker wires for proper connections.
  2. Reduce the volume level. IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.
  3. If applicable to your model, disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the A/V 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 A/V 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 approximately 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required.


My $.02...


Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

hope this will help...

Onkyo DR-UN7 DVD Receiver remote control code


Nowdays there are CLONE type remotes available form electrical stores.

These clone type remotes carry all the codes necessary to work TV, Vdeos, CD players and other domestic sound systems.

I would suggest that you visit one of these stores and see what they have for your ONKYO system, the cost is not great and you will walk out with a complete remote for your system that will work all the other controls as well..
The stores have a fold out paper list, (thats very long) showing model and manufacturer detail for what codes you need to enter into the new remote to make it compatible wuith your ONKYO system.

Cheers From YUBEUT
