Hello
Can't make sound from mono to auto is your problem I thinks and posts this solution.
Hit the "Menu" button and surf through, come to "Sound Adjust" window.
The settings allow you to change and adjust sound in your TV. There are Bass, Treble and Balance control to adjust to your individual taste.
To adjust them
1. Press Menu button.
2. Press UP or DOWN button to select the desired item.
3. Press => or 4. Press EXIT button when finished.
When adjusting the parameter of "Balance" control, always set it to mid position to get stereo sound from both speakers. If it is set to any extreme end, there will be no output from the speaker of that side, and will hear as mono.
If you press "0" [Zero] button, you can reset the sound settings to it Factory settings.
To select 'Streo mode;
1. Press "Menu" button.
2. Press UP or DOWN button to select MTS [Multi-channel Telivision Sound].
3. Press => or [The ON AIR arrowtells you if a broadcast is in stereo AND/OR contains the SAP.
Press "Exit" button when finished.

Keep the TV in stereo mode to get the best sound quality. The sound will work in stereo

mode even if a certain broadcast is in mono sound only.

Choose the mono setting to reduce excessive noise on a certain channel or broadcast.
Selecting SAP will allow you to hear an alternative soundtrack, if one is available.

first check the speaker setting in the menu see if the speaker is selected ON. if the speaker is on then check the SAP function of the set. check this with the remote with the MTS button on the remote. keep hitting the button untill the word stereo appears.

Hello
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.

TV: check for SAP or MTS features, set them to STEREO. Also, verify that the TV Speakers are set to ON.

Cable Box: If the box has volume controls, make the volume is turned up. Also, check for the SAP or MTS feature. Again, set this to STEREO.

I hope this was helpful, best wishes.

Your SAP audio function is on. Look on your remote or in the TV menu for SAP or MTS. There are 3 settings, Mono, Stereo, and SAP... set it to Stereo. I hope this was helpful, best wishes.

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.

You can access the menus using the buttons on the set. Go to audio menu, you'll find a setting that says listen to and have choices of mono stereo or sap, choose stereo.

if you are using a digital TV is is possible that the frequency is slightly out or you have poor reception.
do a new channel serch first (automatic if you can
and see what happens
sap may reset also if you do this function.

RESTORE SETTING
If you reset the TV to the factory settings, all your present settings on picture &
sound will be erased and replaced by the factory’s default settings. However, picture
setting in PC mode and parental setting will not be erased.

You most likely have the SAP mode activated. Look for a button on your remote or an item in the on-screen menus of your television called MTS or SAP. You want to set this to "Main" "Normal" or "Stereo" (or even "Mono") mode to hear the regular television sound.

If it is in SAP (Secondary Audio Program) mode, as I believe yours is, you may hear no sound or a different audio program. Often this is a translation to another language, such as Spanish, and other times (notably with PBS stations) it is an unrelated audio (often music) feed. On some stations there may be no sound at all with the audio mode set to SAP.
