There is no problem with the amplifier audio,check some resistors or disconections near the spkr terminals.

I have an Integra DTR 20.3. Recently, I have been getting no sound from the speakers after removing the headphones from the headphone jack. Any ideas?


Usually the headphone jack has a contact that's "made" by the 'ring' section of the jack when you push in the plug, which bypasses the speaker circuit (that's what automatically silences the speakers when you plug in the headphones when there are no switches to turn the speakers on/off manually)... if the 'ring' strip got bent somehow so it's pressing against that contact all the time, it won't let the speakers' circuit come out of bypass. Look inside the jack with a flashlight... the sideways Vs that touch the 'ring' sections of the stereo headphone plug should be about in the middle of the opening... if they're pushed over too far it may require disassembly to bend them back to the proper position.

The speakers no long produce sound after using the headphone jack,,disconnected jack , still no sound


When you plug in the headphones, the jack itself routes the signal away from the speakers. When you unplug the headphones, the jack has contacts that close again, routing signal to the speakers. If the jack contacts are dirty, they won't close correctly. I suspect were you to clean the contacts, you'd solve the problem.

Pioneer VSX-456 headphone jack problem


No the headphone jack doesn't disable the speakers. There are two switches in the lower middle of the receiver that are labeled speaker A and B. Pushing one of these should disconnect the speakers from the receiver.

No Speaker Sound, Thinks Headphones are Plugged in


If you don't plan on using the headphones - take the cover off and there may be a cable to the headphone jack board that can be unplugged. This will disable the headphone jack from sending a bad signal to the micro. If you want to be able to use the headphone, then the jack is going to have to be replaced.

I have a pioneer VSX 920 receiver that thinks i have headphones pluged in. I have no sound from the speakers and when trying to go in speaker related settings it displays: PHONESIN on the receiver. If I...


I think I just fixed a unit with the same problem. I opened the cover and found where the wire from the headphone jack plugs into a board just beside the power supply transformer. When removed, the unit appeared to select speakers as the output. Since the headphones are never used by the owner, I simply left the headphone cable unplugged. Unfortunately, I didn't have speakers to test it with but the unit appeared to be working correctly.

No sound driver


Turn the power off. Wait about 10 seconds,then power up again get close to the reciever and listen for a click-not from the speakers ,fromthe recievers itself.If you hear a click,you can assume that the power supply is ok for that cercuit.This does'nt eliminate the power supply,but it will do for now.Put the speakers close to the reciever,what you will do now is to power up the reciever while listening to the speakers with the volume off.In about 3-5 seconds you should a hear a slight click from the speakers. Try this with both speakers if you don't plug in a pair of headphones to the headphone jack and play the source . If you still no sound with headphones you at least now know that the output transistors are not the problem or the only problem.The power amp., section are defected also.Message whatever happens.

Headphone jack does not work


your headphone jack is corrupted in internal, cause when you put your headphone jack in internal you activate the switch to switch speakers to headphone and this switch is out of order.
you have to go to a specialist to replace your headphone jack on your amplifier. sorry for this bad news. ;)
