No sound through speakers

I am not getting any sound through the speakers however I am getting the audio to the jacks. The DVD pportion works ok but again no sound to the speakers. When I toggle the speaker test there is no sound there either. All operations are working ok with the exception of no sound to the speakers. Any answers???

    Swapping or defining the cause as board problem is not the answer I was lookng for. The problem is likely the board but my concern is that this has occurred more than once before and it could be a characteristic type of problem. I have removed the cover and there is no visible indication ( such as fuses, damaged components, etc). Please review and see if you can provide another remedy.

If the speaker test fails with no sound, then the output amplifier section is turned off. This can happen if a problem is detected internally and the section is disabled. The shutdown occurs to prevent further damage to either the speakers or the amplifier section. If you can solder, you may be able to repair this yourself. I don't have the listing for your model with me at the moment, so I can't give you all of the probable parts. Please confirm that the model is DAV-S300 as well.

Thanks,
Dan

It seems like the amplifier IC or transisors became defective. In order to replace them you should know how to solder and read a schematic diagram to perform different test on the circuitry before you can pint point the defective component.
How old is your system?

If you can also try using another audio jack just to make sure that it's not a problem with the audio cable..

Hope that helps.......

Rear speakers do not work , also in set up menu they are grayed out.


hi there

when playing radio, the rear speakers do work because you have configured that. in your dvd player however, you may not have configured it yet.

Correctly insert the jacks at the back of the dvd player and at the same time, check the menu of your dvd player and check the audio settings. Under the audio settings of your dvd player menu, select the 5.1 or 6.1 audio profile.

hope this helps.

No sound on my technika 42" 3dtv


If the headphone jack socket works the audio output for the set is good, I suspect a dvd etc will also work if connected to the rear input audio and video jacks.

This does not leave too much, headphone jack dirty or defective, speakers for whatever reason are switched to off in the main menu.

the sound for the headphone socket if it is built into the set is the same audio going to the speakers.

My lg mt-42pz41v speakers are not working


if built into the set check to see if speakers are turned on or off in menu.

If using a box of some sort for signal via rear jacks of set unplug it and plug it back after a short wait to see if the box will reboot and work.

Another simple test is does a DVD etc work via the rear audio/video jacks and have sound? If so the set is ok.

I can hear the sound in headphone but built in speaker are not working. what to do


Hi, Check the following,
  • Speakers, connecting cables and Sound Card are working fine by connecting to another computer.
  • OR
  • If the connection ok increase your volume and open the cable from the pc.
    Now you will touch the stereo jack, can you can listen a sound when touch the jack. If you will not get any sound, think there is the problem in your amplifier or audio system has not any voltage. To confirm the voltage check by multi miter or can go any local Technician .If the voltage is ok, think your sound system defected and should go to Technician.

  • If your sound system is ok
  • Speaker Cable connect to an audio port (Audio/Video port in system box).
Hope this helps ,

I just bought a RCA rtd3131 home theater system. My husband trashed the manual and i can't get all the speakers to work when the cable is on. When the DVD is on all the speakers work but the sound is not...


If the cable tv has audio out jacks, or if you have a cable box with an optical audio cable, plug either the audio jacks into the RCA system or the optical audio cable, and the system should automatically simulate 5.1, through Dolby Pro Logic II. All speakers will not be at the same volume as they are simulating surround sound, not just playing the audio.

The TV will never have sound for the DVD as this system has no audio out puts. Realistically, most televisions have 10w speakers, and this system is 130w, so the TV speakers are useless in comparison.

Left speaker gives no sound


There could already be a problem with the speaker jack, if only one channel is consistently giving no sound on your system.

Try turning the male (connected to speaker wire) jack and you might hear a static crackle while doing this. If you get both channels to produce sound this way, you already have a failing audio jack, and may need replacement later on.

Hope this helps.

Whoa,ok.Sounds like things aren't connected properly.The first step is to disconnect the TV and concentrate on getting sound from a dvd or cd.Read the owners manual and double check that the speakers are hooked up correctly and that the unit is in the correct surround mode.Next, connect the TV.Use an RCA cable to go from an "Audio out" jack on the TV to an input jack on the Teac -e.g. "Aux, TV, etc.If your TV doesn't have the proper jack, I'm afraid you're out of luck.

Sound wont work right /not much at all


Headphone connector is usually designed to pass audio to speakers when the headphones are disconnected. A corroded or bent connector will lose audio. Does the headphone audio level seem ok? Try inserting and removing the headphone jack several times to clean the connector.
