Akai LCT3785TA stereo vs. mono issue

Hi,
the mono could be a red herring, the TV will toggle to stereo when it senses the Nearly Instantaneous Carrier And Modulation signal (NICAM) and as there is no sound it will not be getting that so its showing the default Mono. This could be a simple case of low signal, unless the affected stations are foreign and filter the sound trap at a different frequency

It does not mean much---sound may still be stereo but channel change often does not allow it to show.

With it on a channel listen carefully and switch it if possible from mono to stereo to see if hear mono or not.

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.

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.

to eliminate the problem just select the mono sound disable the stereo signal.so that your tv sound will be stable.this happens because not all tv stations are broadcasting on stereo signal thats why your tv keep on switching to mono and stereo base on what signal it receives.plus the signal being feed by the cable provider sometimes they are not stable enough to give the stereo signal so better select only the mono sound...tnx hope i helped you..

please rate my help!

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't convert mono to stereo since the TV only has a single input, and not the separate right and left channel circuits needed for stereo. If you are connecting a stereo source like a DVD player, what you can do is combine the right and left channels into one and connect that to the mono input. You need an audio Y-adapter with two RCA jacks going into a single RCA plug. These are available from Radio Shack. If you are outside the US, there should be local sources such as a stereo shop where you can find the adapter. This won't give you stereo, obviously, but you will have all the sound.

The solution is to change the audio input from SAP (secondary audio programming - default on TV sets sold in Canada) to Stereo or Mono. Your remote will need to be able to access the "Menu" settings screen for your television set.

Check if the sound adjustment is in STEREO-SAP-MONO mode

Change to STEREO mode

Bear with me...I will start talking about CC, but I think my solution may work for you, too. I noticed that every time I turned on Closed Captioning, when I changed channel, it went off.

I went into the on-screen set-up, and turned on the CC there. Now, when I turn OFF CC, then change channels, it comes back on.

So, it may just have to do with your set up. Go there and set the default sound to stereo and see if that fixes it.

Good luck.
