Question about GPX HM3817DT Shelf System

1 Answer

The right speaker output jack produces no sound through the speaker. The wires were switched to insure its not the wires. The jack itself is not working. I have used this product for a month and it had worked fine. It has not been moved, it has just stopped working. I cannot find my receipt to return it.

Re: The right speaker output jack produces no sound...

Hi There, 11.11.2007
There are several things that could have caused this to happen.

But first there is a simple test you can do as follows.
Take a small battery out of one of your torch's, a small AAA or AA type they are usually 1.5 volts.

Disconnect the faulty speaker wires from the rear of the amplifier system and by tapping the speaker wires to the terminals on the small battery you should hear small clicks coming from the speaker...If this happens OK then you know the speaker and the wires are all OK and the fault must be inside the Amplifier system. But if you dont hear any small clicks then the wires to the speaker or the speaker itself is can try this on the good speaker and see what the clicks sound like!!!

Clicks means its all OK,
No Clicks there must be a faulty cable or a blown speaker...

The next thing to consider is were you playing the music at full volume when the speaker went faulty???

There is usually protection devices within the amplifier to protect the speakers from overloading, and its possible that this device has tripped on the faulty channel.

Sometimes there are fuses which are accessible from outside the amplifier case which you may be able locate then replace.

But if there are no fuses then the amplifier will need to go to a service person for attention. I dont recommend that you take the amplifier apart yourself as there are dangerous voltages inside that can cause you serious injury, and a service person is trained to look inside safely......

Cheers for now... yubeut.

No sound comes out of the system/speakers on my FW-C255/37

There is a problem with the headphone jack or there is a audio output problem, get some electronic contact cleaner attach straw and spray inside the jack, push the headphone jack in and out quickly and spray again and repeat, this should clean the contact points, if no sound, audio output should be suspect.

Sound to right speaker goes in and out, mostly out after a few minutes. checked speaker wire connections. they are ok. switched speakers to no avail. Do I have a bad chip or circuit?

there could be a dry soldering joint on the Right Output of the audio chip inside the unit. As the audio chip heats up, it warms the board up aswell and this can warp it causing the sound to cut in and out.

My sony 771 won t play any sound -- not the speakers because doesn't come through headphones either. Just cleaned the lens for CDs last night, then this problem developed. Can see the amp bars moving, so...

The lit indication ("amp bars") proves that the aduio signal is getting through the unit's circuitry @ least to that point; lack of sound @ the spkr & headphones indicates the amplifier portion of the circuitry is either inoperative or disconnected from the load (i.e., either the speakers, or the headphones). A common cause of this type of problem cropping up unexpectedly is the headphone jack itself; in most products of this type, the audio path from the amplifier output to the speaker connection runs through the headphone jack, so the the speakers may be "turned off" when the headphones' plug is inserted into the jack. If the unit's owner uses headphones regularly, the most common problem to be found with the jack is loose solder connections to the printed circuit board's traces from the jacks' lead(s); in units with this problem whose owner's irregularly use the headphones, it's more common to find oxidization of the electrical contacts within the jack itself.

My RCA RS2622 sound stopped working.

I'll need to look up your specific model to be sure, but I believe that the speaker outputs come from an amp pac. The headphones are driven by an opamp IC. The outputs are blown on this. If you can solder, you should be able to repair this. I'll look up the parts required and get back to you.

Lost speaker output at rear of unit

Check the continuity of your speaker cables either by using them on another system or with a test meter. Could be that the cables got damaged in the move.

TEAC - CD-X9 - No sound in left speaker

the speaker wire itself could be grounding out. look for small knicks in the wire and make sure the plug is not faulty. RCA plugs can go bad which would account for intermitent troubles some times

Right speaker jack

Are you using the same cord for the mp3 player as you are for the cd and radio? There could be a patch cord problem or it could be the output jack of the mp3 player. If using headphones with the mp3 player works both right and left then it must be the patch cord. Try using a different patch cord.

My Emerson NR305TT will not produce sound. Turn table works, CD Player works, FM Tuner Works, everything works except no sound comes from the unit. The on switch and volume seem to work as I hear a faint...

You have one of 3 problems:1) bad solder joints in the amplifier or preamp section 2)defective output transistors/ICs in the power amp or 3)missing or incorrect voltages to the amp section. If the unit has a headphone jack plug in a headset. If you have sound then everything is OK thru the preamp section and your problem is in the power amp. Any competent repair shop should be able to solve this one easily.
