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

  • tjalbrecht Mar 13, 2009

    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?

Reset receiver

If it's in protect mode that usually means a fault in the audio power output stage(s) Must likely a shorted output device,Some receivers have intergrated circuit outputs that may be the problem, you need these problems can be quite hard to troubleshoot if you don't find all the problems any new parts you install can turn to junk in the blink of an eye(or less).

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.

Protection overload and the system shuts off

check your speaker wires for short, try to turn it on without speakers connected, if all connections and speakers seem ok the problem is internal witch can go from blown power supply to shorted output devices and everything in between , and as always look for repair shop in your area, do not attempt to do it yourself, fire hazard and electric shock are the things we all want to avoid ;)

Amp output is damaged and needs repaired. Protect mode cannot be deactivated. When amp is repaired and operating normally protect mode will not be displayed.

Harmon Kardon AVR300.**protect** blinks when powered on.Took cover off no obvious problem.Disconnected EVERYTHING from back panel,still blinks **PROTECT**.

The protect message means that the outputs are shorted. This is a fairly common problem that can easily be fixed by any shop that handles audio gear. Expect a parts cost in the $20-$40 range.

Connection problem with HDMI cables on Denon AVR-589

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.
