Are you using a cable box sush as a Comcast cable box? If so then the volume control within the cable box is most likely not high enough for the TV to detect a stereo pilot signal. The Comcast remote (if thats what you have) still is programmed to operate the volume within thier box, the volume display will be at the top of the picture and it will be in white. Turn it up until the word "stereo" appears. then leave it at that setting and use your TV's volume control only.

My remote broke and some of my channels are on sap. and when i go to the menu there is no audio setting how do i put the channel setting back to stereo or mono


While receiving an MTS broadcast, press [Audio] repeatedly to to cycle through the available channel.
Main: Outputs main audio.
SAP: output secondary audio programme.
Mono: Outputs mono audio.
You must ahve remote control to change these, because only remote control have Audio button on it to control these. OK.

I think that my TV soney braiva xbr has an issue with SAP but some ch. are in spanish some do not have sound How do i reset this tv?

Press MTS/SAP on the remote (under the number buttons) to go between the 3 options of STEREO or MONO or AUTO SAP. Not all channels will have SAP (secondary audio program). Selecting stereo should eliminate any secondary audio.

Audio only has mono how do you change it

If you open the menu,there should be an option for sound.If you have a universal remote,you will probably have to do it with the buttons on the TV.SAP and stereo are about the same.It most likely cycles through mono,stereo,SAP with the volume button.Good luck!

I've been having this audio issue with my LG 19LG30 for awhile now. Only recently discovering what exactly was going on. My audio would go in and out on some channels. There would be sound then muted for a...

to eliminate the problem just select the mono sound disable the stereo 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 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!

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.

In the audio menu, you should be able to select stereo or turn off sAP -- you may have to unplug the set for about 20 seconds and restore power to reset it, or return it if the problem doesn't go away. If you end up replacing the set, try for a JVC, Panasonic or Toshiba if you can switch. I think they will last longer for you.
