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).

How do I get my rca truflat tv to get out of mono?

Press the MTS on the remote control handset to select STEREO, MONO or SAP. All the options will be available only when the current TV channel is broadcasting that option. Channels will not always carry programes, that have all MTS options. If "STEREO" appears on the screen when you select a channel means stereo sound is available with current programme. You can hear sound from both speakers. If broadcast is not strong and clear, stereo sound will not be available. Press "MTS" button to change it to "Mono". This will eliminate the noise. If "MONO" appears on the screen when you select a channel, stereo effect will not be availabe, even though you have set it to stereo. If "SAP" appears when you select a channel 'Second Audio Programe' [SAP] broadcasting is available for that programme. Press the "MTS" button to 'SAP' and you can hear that programe in different language or some other kind of audio.

There is no sound on some channels on my hisense tv

Locate the SAP or MTS feature by TV remote button or TV Audio Menu. It needs set to STEREO. SAP or Second Audio Production is not used by every broadcaster. In those cases, you will have no SAP audio on the channel. I hope this was helpful, best wishes.

No sound on some channels, other channels fine

Your SAP/MTS function is most likely turned on. This feature has 3 modes: Stereo, Mono and SAP. Stereo and Mono are easy to understand, it's the SAP that can get you. SAP stands for Second Audio Production. It is used to provide weather, information or an additional language translation of a program. Some broadcasters simply transmit the mono audio over the SAP audio channel when the are not using it for other purposes. Other broadcasters simply do not use it, which does not give you any audio. Look on your remote for a SAP or MTS button. If you do not see one, look in your TV user menu for this feature. If you are using a cable box, look in the audio menu of the cable box. You are looking for something set to SAP... just change it to STEREO. I hope this was helpful.

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
