Question about Harman Kardon AVR 310 Receiver

Avr310 no audio output

Everything else seems to be normal. Pops in and out of protect, but no audio output

    With no actual source connected, and setting on "6 channel direct" input, I get voltages on the speaker terminals that vary from .014 to .040. They do not change with the volume control, even with a signal (CD player) playing.

    Does anyone have the service manual for this device?

    Everything else 'appears' normal. I did find one capacitor that was bad, a 6800uf, 16v. I replaced it, still the same problem.

    Any ideas?

Sony km7500 no audio output


If the signal goes through this chip I really hope it's no smd.
Change out this chip and check the capacitors around it; resistors too.
Have you tried a signal at the beginning of the actual pre-amp on your print? After this chip? Do you have a signal then? If so, it's obvious to be this chip. Succes.

Protect mode jvc


The protect mode is activated when it senses a short in the audio outputs in the stereo. Turn volume down, power off, and remove speaker wires from the back, next power on, if the protect comes on the audio output ic is shorted, if on the other hand it runs, check speaker wires for shorts and then hook up one at a time to find the fault including the speaker.

MY KICKER ZX 750.1channel amp "FLIP FLOPS" from protected mode(red light) to normal (green light) every 2 seconds.


Are you getting any sound output at all from amplifier?
Is there a popping or banging coming from speaker?
It could possibly be a faulty output mosfet that is ocillating cause DC to leak onto the speaker output causing it to flip into protect.
please advise
thanks,ben

Audio cuts out on Bose AWRC-1P


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

Connection problem with HDMI cables on Denon AVR-589


Hello,
I want to clairify you install, you sat you have I an HDMI cable running from the Time Warner Cable box to the AVR-589, going in to the TV/CBL input. From the Denon AVR-589, I have an HDMI cable running from the output to my Toshiba RV525U television.

Check the connection at the TV, if as you indicated above you have an HDMI cable from the HDMI out from the Denon to an HDMI output on the TV, if this is the case you need to have that HDMI cable plugged into an input on the TV not an output

I have a pioneer 5.1 channel surround sound system and it powers up and everything seems to go fine but you go to turn it up and no sound comes out of the speakers already checked speaker wire connections...


Does the protection relay click 3 to 5 seconds after initial power on??? If not, your unit is staying in "protect" mode to save your speakers because the output transistors or output IC is shorted and sending 40 to 60 volts at your speakers. Not a good thing, but at least it saves your speakers.
Good Luck!

Protection on display


disconnect everything from the unit and see if it still does it.
if it does i would check the output transistor (ic).

"Protect" feature increasingly activated.


You may have an output transistor gone bad and it is trying to run on one good transistor since they commonly are used in pairs (one positive and one negative). Time for a trip to the shop. Good luck.

Protection Light Keeps Popping On


Yes I would certainly say there is. Sorry to be the bearer of sad news but you have a short in them thar circuits! Its not a consumer replaceable part that you can open the unit and find a part thats bad and simply replace it. All these parts are soldered in and need a mutimeter at best to test the output and driver devices. It should be taken out and sent to the manufacturer or to a local audio repair center. Good luck
