5 Answers

No Output No Audio Output at all from any of the channels. Mute isnt on. Volumes up. Its not in protect mode. I did notice that when i use to turn it on it clicked twice before powering on. Now it only clicks once and none of the audio or video works. What do i do?

    Reset didn't help either. I think I'm going to have to invest in a new one. :\

    I have a similar problem. Just happened today. Listening to music as usual and the sound just cut out. Every output, every setting, no sound. The display is on as usual other than the AM/FM setting. The display says AUTO on the left side but doesn't display the setting (LOGIC 7, DOLBY PL II, etc) afterward.



    Opened the unit but no idea where to start. There are 5 fuses which are all good. Likely a bad circuit panel. Any one have any insight? Thanks in advance.

    My problem is exactly as mentioned by a few here. My AVR130 was working geat. It was shut down for a few hours, and when turned back on, there was no output whatsoever. The display looks as though it is receiving the signal from the dvd player, sat box etc, but no audio output or video output. As also mentioned by someone, there use to be two clicks upon power up. The first click is for the power turning the unit on, and after the display blicks for a few moments there is one more click and that is when the audio used to turn on. It sounds like arelay problem. Is there any fix for this?

    i have the same prob with a HK avr 146. i cant find the resistors your talking about for the life of me. maybe ive seen them but dont know how to tell their bad. i looked for a burn or something but im not seeing anything. does anyone have a pic or a general idea of where their located?

  • Anonymous Apr 20, 2009

    kostiko, can you telle exactly where these resistors are, because i can´t find them. Thankx

  • Goods71 May 11, 2010

    Are the resistors on the main circuit board (closest to the bottom of unit)? Do the resistors show actual breakage? Are the resistors the same color as shown from Digikey?



    Do you happen to know the number printed next to the resistors on the circuit board?



    Thanks for any info.

I just want to thank Kostiko. His solution about the fusible resistors is bang on!!!

I contacted Harman Kardon and spoke with three different people giving them very specific information, and they told me that it would probably be a board, and a minimum charge of around $150.00. Add in shipping costs and this fix would have been well over $250.00. I decided to just purchase a new receiver, a Harman Kardon AVR335. Within 1 month it quit working with the same condition. I now had 2 dead HK receivers. After seeing Kostiko's post, I downloaded the service manual, and had a look. It made sense, so I immediately pulled the case off and checked the two resistors which in fact had blown through. I then checked my new receiver, and low and behold, it also had the same two resistors fail. So thank you Kostiko, I now have two HK receivers working again. I guess that I need another set of speakers. BTW Digikey sells these replacements for less than $1.00 each. The part number is PPC.47CCT-ND.

    Great that it worked for you. Could you please explain step by step what you did and where to locate the 0.47 ohms resistors (r901 and r902)? I think that there are a lot of issues with the actual solution. Please help us! Thanks.

  • kostiko Oct 02, 2011

    I will be more specific this time (I won't use resistor numbers because I don't know the schematics by heart):
    The two resistors are located on the TRANSFORMER BOARD serial with the bridge rectifier which is supplying the Aux Power Supply board located on the heat sink. Reason why they blow is the 'big anti ripple' electrolytic capacitors located on the Aux Power Supply, because of the heat, are getting dry or worst 'in short'. They're required to be replaced with the same value but HIGHER TEMPERATURE INDEX ones.
    The short way (if you are lucky) is to replace just the resistors on the transformer board and to solve the problem just by doing this. Do not attempt to use 'more powerful' resistors since they are protecting the board as well.
    The long way is to address the main problem: replacing the capacitors on the Aux Power Supply (the three larger) with some others which withstand higher 'real life' temperatures. therefore, when buying some aftermarket ones, check the temperature index to be at least 80C. So, if you bought all the replacement parts (two resistors plus three capacitors) you have to dismantle half of the unit in order to be able to access the power supply board. As well, you will need to have a very long Phillips screwdriver to access the three screws which hold the board in place (passing through the Voltage Regulators ICs). Remove the DSP board, the Video board and the Digital input board. Be careful when assemble back to not over torque the screws to avoid stripping. As well, pay a close attention to the flat cables when remove/inserting them since they are prone to mechanical failure. After you removed all the boards, you need to remove as well the back plate. To get the job easier, an electric screwdriver with adjustable torque would be handy.
    After you removed all the mentioned boards, the aux power supply board, replaced the capacitors and put everything back you can replace the resistors on the transformer board. To verify if the job is complete, measure with a meter, on the pins of the 'snap coupling board' on the right hand, the +/- 15V which the unit is missing. The pins are marked so you don't need the schematics.
    Hopefully this will help. It is a 1-2 hours job for an average skilled person (which I presume you are) so I wish you all the best.

Actually, the aux. power suppy is defective. There are two 0.47 ohms resistors which are located on the main transformer output board, which are blown. The result is missing +/- 15V for the analog ICs. Replace those and the problem is solved.

The real cause of the burned resistors is the little C, vertically mounted between the mentioned resistors. Remove this capacitor.

Indeed, what Kostiko said is THE PROBLEM. I live in Spain and here I was ready for € 0,30. Whole Harman Kardon said about €150,00. Thanks.

My mackie m800 fell an now it plays for about 30 to 40 min an then goes into protection mode the fan goes into high speed an it mute the audio


Sounds like it's overheating or otherwise overloaded. Check the front panel channel status indicator to see if it's a heat issue (hot vs. norm). I'm guessing there's a short at the output that's putting it into overload after 1/2 hr.

When i turn the volume up from my sony receiver strda3400es de protection comes in. By lower volumes it works ok.


Hello
Measure load resistance. That is the output connected resistance. If it is too low than normal this type of protection will be activated. Measure the impedence [resistance] of speakers connected to the output. It must be more than 4 ohms/channel effectively. OK.

Hi, My Marantz SR4200 goes into protect mode about 45min after cranking the volume up to party mode, ie above '0'. It is getting worse slowly. Ok at lower volumes. Something seems to be overheating,...


Or it could be you're overdriving it, hence the heat. Take a clue and turn it down. At 70 wpc played loudly it could be going into speaker- and self-damaging distortion.

Make sure it has a lot of ventilation.

Won't go off protect mode


When the speaker wires shorted to each other, the output transistors for that channel probably shorted as well. This means that the receiver needs repair. The typical parts cost for this usually runs between $20-$40.

hmmm it seems the output chip isnt getting stable voltage to keep itself running so it keeps turning itself off and trying to protect itself from damage when the voltage keeps dropping

No audio on any channel, even in audio setup mode, no audio headp


If you have any of its sound outputs connected to a TV or tape deck do they get the signal? If so, then we know there is sound processing somewhere inside the unit but not emerging to anyplace that requires amplification.

A quick basic check would be to tune an FM station, run an RCA cable pair from the audio output for a tape deck (see the picture at the link) to an analog audio input on your TV. Select that input on the TV and you shouls hear the FM station, or anything the receiver is configured to play. If it's silent then there is no audio signal circulating in the receiver to get out to the amplifiers.

http://www.onkyousa.com/images/hookup/TX-SR803/detail_tapedeck.jpg

Check to make sure Multi-Channel input is not selected unless that is what you're listening to as it bypasses all other sources analog and digital EXCEPT the tape; and check any Mute or Zone Controls, too.

If you hear the program on the TV but not through any attached speakers, then the amplifiers are all disabled for some reason. The click I asked about before... when you turn it on does it get a click about 5 seconds later. That would be the protection circuitry turning OFF to allow the amplifiers to function.

I notice it has a Tape function. Make sure it isn't selected as it assumes a tape deck or processor is attached and will only play back what would be coming FROM the tape deck or processor. On my Pioneer receiver it also disables any digital signal processing.

Sometimes when I'm watching TV with the remote on the seat someone moves and something bad happens. It's always some unfamiliar button that gets touched unintentionally. Look over the remote for things like MUTE, Multi-CH, Tape.

Protection mode


The protect mode with nothing connected indicates that the output transistors for one or more channels are shorted. These will need to be checked and replaced. This is a simple repair for an experienced audio shop, Figure about $10 for each output transistor and add in another $10-$15 for misc parts that may also be smoked.

Onkyo TX-DS777 goes straight to protection mode


Hello.You have shorted audio outputs. One of your channels has shorted output transistors. If your unit uses output ICs then one of them is shorted. Both types ( individual transistors or ICs ) are located on the large finned heat sink. The parts are available from http:\\www.tritronicsinc.com. good luck

Turn on then shut off


Unit is going into protection and then shutting down. No way to tell what is wrong. Could be blow amp channel or bad power supply.
