Question about Harman Kardon AVR 335 Receiver

1 Answer

No audio Hi Julian. I saw that you posted an intelligent reply to a similar model, so hopefully you can help. ;-) I have an AVR335 receiver that lost its amplified sound (everything else seems to work). I'm good at electronics so I took it apart to see if any obvious burns or other malfunctions could be seen. Everything looks fine but what I gather is a small thermal protector screwed to the heat sink could be the source of the problem. It has a 2-wire cable that is soldered to the amplifier PCB near the two sets of wires that go to the fans. Do you have any info on the sensor and/or how I can test the sensor? I have pictures if they help. Thank you for any thoughts you might have. Best regards, Paul Shepherd

    Solution pending.



    (just fyi).. It was two blown 0.47 Ohm resistors on the "auxilliary power unit". Apparently they are supposed to provide +/- 15V to some IC's.

    Not solved.



    The two replacement fusable resistors (0.47 ohm) keep blowing.



    Any ideas??!!

I know that a couple of you have had the same problem with the blowing 0.47 ohm resistors. I had responded quite a wile back, but forgot to make any updates. Kostiko is correct about the problem relating to these two 0.47 ohm resistors being blown. In my case on two different Haman Kardon models, this was true, but there could also be another issue. What i have found is even after replacing these resistors, the problem appeared to still be there. What was happening was that right after turning the receiver on, the resistors would blow again. What you need to do is replace the two small ceramic disc style capacitors on the same pcb as the fusible resistors, as they could be shorted as in my case. You could remove these capacitors completely, or replace them with a similar size of the same type, as they are really just there for filtering higher frequency noises from the power supply. You can check them with your multimeter first. They shouldn't shorted even in situe. I forget the size, but they are approximately 100 nano farads. Good luck. I have done this to my AVR135, and it has been running great for about 6 months now.

Hi, There should be a very light thumping sound when you power off or power on the receiver. If none, then it is possible that as you posted, the receiver is broken. 3 possible areas where the receiver might be having some problem(s) are: 1. The speaker protection circuitry. This might have activated which is indicative of another possible problem(#2); 2. Your amplifiers are dead; 3. For some reason, audio muting is activated. this is normally caused by the microprocessor not detecting any intelligent audio input and mutes the audio before going into the preamp stage. Examples of this are when they FM signal is weak there are more hiss than intelligent sound. But as you posted, there seems to be a station that it has locked into and an antenna is installed. If resetting the unit and trying other signal sources such as CD player or MP3 player, or even your fingers on the positive end of an RCA plug and likewise trying the different RCA inputs and selecting the source as the case maybe, and you still do not get any sound reproduced from the speakers, then it is probably safe to say the your receiver needs some repairs. Since this involves electronic circuit diagnosis, probably soldering and replacing some components, perhaps your best bet is to seek the services of a qualified professional. Hope this be of some idea/help to you. Good luck and kind regards.

You need to post up the exact make and model of the remote and also the exact make and models of the devices you want to control.

As soon as you provide this information we can hopefully determine what codes you need.

Many thanks.

Harman Kardon AVR


Have you solved your problem?

I had the same problem (no sound) as well as several other people with other models (mine was AVR335).

I'm replacing the 1W 0.47 ohm resistors with bigger 10W 0.51 ohm ones that i happen to have on hand.

I'm curious if you have it working now.

My amplifier


Hi,

The "switched off by itself" is indicative that the auto-protect is acting. Auto protect senses that there is something wrong within the unit and rather than the damage extend to other areas, it simply switches the entire unit off. On some models, this also hold true if there are no or faulty speakers connected to the receiver. In others, this happens when there is no intelligent signal received such as in FM when an antenna would be required.

If you have verified that it is not poor signal, speaker problem, then perhaps your best bet would be to seek the services of a qualified audio technician since this would involve electronic circuitry/component diagnosis, soldering and the use of a DVM.

hope this be of some help/idea. Post back how things turned out or should you need additional information.

Good luck and kind regards.
