Audio Problem - Can't turn the 'stereo' feature on the MTS

Recently had problems with our TV. Have no sound on 3 or 4 channels and one channel has the descriptive video function on and we can't turn it off. When we went to advanced audio menu we can't get the MTS feature to go to stereo. It won't let us highlight stereo for MTS. We're not sure if it's the cable box or if it's the TV, any ideas?

It aint your tv,, if it was it would have been on all chanels,,, My thoughts would be to call the cable company....

dont bother to fiddle with your tv...
if it was your tv it would have been constant and on all channels.. not just 3 - 4

No sound,but good pic.everything else works fine.(toshiba 57hx94)


• Check the antenna/cable connections (see Chapter 2).

• The station may have broadcast difficulties. Try another channel.

• The sound may be muted. Press VOLUME.

• If you hear no sound, try setting the MTS feature to STEREO mode (page 81).

• Make sure the SPEAKERS function in the AUDIO SETUP menu is set correctly (page 83).

• If you are not receiving a second audio program from a known SAP source, make sure the MTS feature is

set to SAP mode (page 81).

• If you hear audio that seems "incorrect" for the program you are watching (such as music or a foreign

language), the SAP mode may be on. Set the MTS feature to STEREO mode (page 81).

• When using an external audio amplifier, if you connect the amplifier to the VAR. AUDIO OUT jacks, the
volume of the TV and amplifier must be set above 0 or you will not hear any sound (page 20).

I can get a picture , but no sound on the TV . What am I doing wrong?

Many RCA TV sound problems are caused by SAP function being activated by TV station equipment that converts Analog TV signals to HD signals. Accidental pressing of the wrong buttons on your remote can also cause this problem.

The incorrect conversions causes the Audio settings to be changed from Stereo to SAP by the received signal.

Solution is to go to Audio set-up in customer menu and change settings from SAP to Stereo. If you find that settings are wrong, change them to "Stereo". Do channel scan if you are using the TV tuner/remote to select channels. Turn off the TV and unplug for 60 seconds. Check the settings again and reset if required.

This problem may re-occur when you select the VHF channel, satellite channel or cable box channel that is causing the problem. It is not a TV fault that can be repaired. The problem is caused by the incorrect incoming signal.

SAP is Second Audio Program, used for second language transmissions.

Second cause may be that the speakers have been turned off in the audio set-up menu.

No sound on some channels

your tv has audio setting called SAP that is for channels that are broadcasting on a second language like spanish, on the channels that do not have this SAP capabilitie you will not hear anything unless you put your tv on stereo mode, so you need to go out of the Sap mode by a button on the remote, check for mts, button , or audio thank you

Programming Channels

If the set has been unplugged or has had a disruption in the power it may have to be setup again. Try going into your menu and go to the setup . Look around in setup for channel search of some kind. The set will search for channel signals in your area automatically once you tell it to. Then you should have the channels back. If this works then after it has run its search go to the AUDIO part of the menu and check that mute is off and that you did not turn off the internal speakers. If you are lucky and your set has plugins for external speakers, you can just get speakers to use with the set, but this is pretty rare. Check the rear panel on the set and see whats there. Most sets have an AUDIO OUT plugs that will pass the sound through your set to a home stereo for sound. Just run the lines from the audio out on the set to audio in on the amp or receiver of the sound system you have. Audio out will have a red and white plugs and just keep the red to red and white to white when hooking it up.

What channell do you tune to for dvd output for durabrand model Dwt 1905


I believe its not on a channel but on VIDEO. Chances are you have the DVD hooked up as Audio/Video using the RCA cables (yellow, red & white). The TV must be set to Video IN not TV Tuner/Channel. Additionally, your TV can only accept a mono audio input while your DVD's audio output is stereo. A quick and dirty way out is to use an adapter shown below to convert the stereo to mono. Additionally, to my knowledge your TV's Audio/Video inputs are on the front panel.
Alternately, if the front panel Audio/Video connector is already being used by another device, an RF modulator may be used and this time your TV has to be switched to a channel prescribed by the RF modulator. A fine example is one from RadioShack.

In some instances, there are DVD players that has a built-in RF Modulator and normally uses either Channel 3 or 4.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Audio Problems

First for the Toshiba could the SAP (Second Audio Progam) be turned on this will somtimes cause the audio to drop. And are you using the onboard tuner or does this set conect to a cable box?
Then for the Panasonic the most common problem for your fault would be the convergance curcuits are shorted and need replacment, or some other componet may be loading down the set and forcing it in to shut down, Tv's will do this to prevent further damage

No volume

Normally when you have only one channel with audio the cause is usually SAP is turned on, either on the television or the cable or Sat elite box.
If you were pushing buttons on the remote, I would suggest that the SAP button is on the remote.
On a Samsung remote, the MTS button identifies this function. It may be labeled stereo.
Make sure the remote is in the TV mode to change or check on the TV.
It may also be a button on the remote for the Cable or Sat elite box. If not then you may have to search in the menu's of the Television or the boxes.
If the set is only two weeks old (the actual set, not how long you have owned it) then it probably has an ATSC turner labeled Air that will receive local HD by using rabbit ears. If the set is over 3 years old, it will not have this feature.
It's difficult to give a full de script explanation of a solution without knowing the model or configuration of the input signal.
If this does not help, respond to this post and I will reply.
