I recently lost my remote and some channels are on SAP and I get no sound with those channels. Just need to know how to change it back to STEREO.

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.

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.

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.

your set is in the SAP mode go into the cutomer settings and locat the sound setting and turn it to stereo

If you have lost sound on only one station and are using cable or an antenna directly to the TV. Look in the audio settings as most likely the SAP mode is turned on. If the TV detects a SAP signal even if there is no audio this is what you will end up with.

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.

on your remote there should be an MTS button, try that because sometimes they broadcast shows in/on mono,stereo or sap. go to those channels and try switching to either mono,stereo or sap. let me know and good luck

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

The set is definately in the SAP mode, which will have some channels in spanish and some channels with no sound at all. You might be able to get an inexpenxive universal remote and go through the menu to return the audio setting to stereo, but if that does not work then you can order an original Sony remote by model number from Union Electronics at 800-648-6657.
