Question about Harman Kardon AVR 130 Receiver

1 Answer

On my AVR 130 the output is switching off now and then. By pressing the small output channel button it is switched on again. Can someone tell me why it is switching off by itself ? Display says nothing just normal.

Dear every channel in the pvr must have exact ohme so if your speakers are 8ohn you must change settings on the pvr to be 8ohm it's by stander 4 ohm so you can plug 2 speakers 8 parallel way

SOURCE: Harman Kardon AVR 120 turns off by itself after normal work for about 1 min

Followup on higlider's problem. Now it has to be turned on ten times before it stays on. Email from Harman Kardon only suggests taking it to an authorized repair shop. It is clear that it is not from speaker short or overheating, because it only happens when the rcvr is cold.

Check the fuses - there may be one inside the box as well. May also be a bad transformer. You can get a multi-meter at Home Depot and lookup how to check the power at the transformer.

If it's not overheating then check the setup menu for a time set for an automatic turn off.

There is an internal reset switch mounted on the transformer board. Open the unit, look at the boards attached to the transformer, the pushbutton is facing up. Measure the voltage on the 2 pins of the switch. If it is a logic low, the switch is partially shorted. Replace the switch or just cut the jumper wire just below thw switch. When this switch fails, it constantly resets the receiver and stops it from powering up. It does not fix a protection mode problem.

try to reset. Unplug the unit, press and hold speaker A and speaker B buttons and plug the unit in outlet. If doesn't help, the unit may have a problem with microprocessor or dsp boad and need to be serviced at a repair shop.

No sound


There can be any number of reasons for this problem - solve it diagnostically by starting with something that you know is working and work through systematically to the other end.
  1. Test a microphone on a separate amp to make sure it works okay. Check amp and speakers working. Check that all output cables from mixer to amp are working by testing separately.
  2. Plug microphone into a channel on mixer. Also plug in headphones and turn headphone volume control up.
  3. Make sure input sensitivity knob is turned up a bit (say half way) and main output faders (yellow) are up.
  4. Check that channel is turned on (little button just above the channel fader- needs to be pressed down)
  5. press pfl (pre-fade listen) button (next to button to switch channel on)- do you get any sound on main output or headphones or any indicator lights on mixer to show signal is getting that far (eitehr the individual channel metering lights or the main ones in the central section)?
  6. turn off pfl - make sure channel fader (slider) is up - normal position is ) - about 3/4 of way up. Check lights again on individual channel and main output section - any signs?
  7. Is the sub mix button for the channel pressed down - in which case you will need to bring sub mix (red) output faders up as well as main faders.
  8. If you have got signs of signal on the individual channel but not main see if the channel has been routed somewhere odd (like a subgroup of channels).
  9. Plug a working amp and speakers into one of the auxiliary outputs and use the relevant auxiliary send knob (on each channel just above the faders and pfl switches) to pan some signal to that auxiliary out - do you get anything? There is also a headphone socket for listening to the auxiliary channels (with a selector switch /knob to determine which one - make sure it is in the right position) try listening to the auxiliary output with headphones - anything? If yes the problem lies in the main output section.
  10. Check that there is not a jack plug in the insert socket (to route signal through an external effects unit) without a matching return jack being plugged in - if appropriate is relevant effects unit switched on and correctly set up - if unsure remove the insert plug to take it out of the system.
  11. Make sure any mute buttons are not switched in on main outputs.

Hit some buttons, now i can get 7 channel output.


Get into System Setup and run through the Speaker Configuration routine. My bet is it thinks you don't have Surround Back speakers.

AVR 684 was working normally then shut off with rapidly flashing red led. Have allowed to cool overnight, tried different power sources, disconnected speakers etc, etc. Any ideas?


The unit more than likely has a fault in the power supply or the output stage. Common switching power supply problems are the FETs used for switching fail or the PWM generator fails. Output circuits can be configured many different ways. The trend these days is to use integrated high power amplifiers for each channel instead of discrete push pull amplifier stages.

Denon AVR-3300 component channel switch burnout?


hi there, i don't have a solution unfortuantely, but i may have the same problem. I have a denon 2802 av receiver, i bought it second hand and I can't seem to get the component video in / out working. Are you supposed to just plug it in and it works? Because I can't find any buttons or settings to select component in / out as my input / output sources?

It's likely that you have shorted some speaker outputs, I had that problem and sorted it. Unfortunately it does mean replacing some output transistors..the devices are dificult to get to just to add insult to injury. They are the devices that are mounted directly onto the large heatsink and solder connected to the bottom circuit board. You only have to change the matched pair that you have blown....tricky to identify which ones without some electronics knowledge. The power output section does have some fuses to protect it but sadly these do not appear to be fast enough to stop "one" from damaging the power output stage if you unfortunately short outputs. The transistors are available from Farnell, use pin compatible replacements SAP15N and SAP15P.....all the best. Doctor Bill

Hello, I think that you've got a problem in the relay circutry or a logic problem. tell ya what I ve got the service manual and schematic for the reciever. the engineers at denon where ahead of there time when this company started. they designed the equipment around what they wanted the specs to be for signal to noise and discrete audio channels. each of the sound channels from the component and composite inputs is given its own bus and amplifier channels. these paths are also common to the reciever/tuner outputs. one question though you mentioned that the composite/component video paths are not switching from the input to the output youve designated, and that the monitor checks good. do you have another video source,either digital or analog that you can input throgh another channel to see if it is infact a switching problem. try that and let me know. I can give you help with the switching circutry form the schematic if need be. believe me I know It took me about a week to track down the service schematic for this unit. Denon doesn't like giving out info unless you are an authorized repair center.

No Power


I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK
