Why the sound only on certain channels and some channels start speaking Spanish?

You most likely have the SAP (Second Audio Program) feature enabled. Many shows do not have this sound track and that is when you hear nothing. When the SAP is on, it is usually in Spanish for English-speaking programs. Check your TV remote for SAP and see if you can disable it.

How to I disable the SAP function on RCA FLAT 19 INCH screen?

From its main Menu, surf towards its sound Menu.
By using UP/DOWN buttons of the remote handset, select SAP

SAP (Second Audio Program) (for analog channels only) Plays the

program's audio in a second language, if one is available. The TV displays

the word SAP in the channel banner when you tune to a program that is

broadcast with SAP information. SAP audio is broadcast in mono. SAP is also

used to broadcast a program's audio with descriptions of the video for the
visually impaired. Press the right arrow button to turn SAP on or off.

Under the channel it says SAP and no sound comes out on some channels,on other channels its says stero and works fine how can i fix the problem

I found this information in the manual, and perhaps it will help:

1 Switch the audio.

• Every time you press [AUDIO], the audio will

be switched as below.

MAIN : Outputs main-audio

SAP : Outputs second audio channel
MONO : Outputs mono-

Also the manual says this about SAP:


(Secondary Audio Program)

Second-audio channel delivered

separately from main-audio channel.

This audio channel is used as
an alternate in bilingual broadcasting.

Here is a link for the manual, in case you want to go over the settings. I'm thinking this is a setting problem in the menu, but it can be a physical problem with a cable line.
Of course it could also be a trickier problem, but check your settings, check the cable line with another TV if possible, and then contact ILO Support for help, in the event nothing fixes it.
Good luck, and hope this helps.

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.

I have no volume on channels 2 and 7. All other

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.

Toshiba TV sound vanished

It is possible that the TV set has an SAP (secondary audio program) setting that has been turned on. To check this go in the the menu, find audio settings, usually the correct setting for this is Stereo, other setting may include Mono, Surr-Stereo, etc.

How do i program cable channel in to my 27" tv ,,only has local channels 2-13 when we use auto program, no other stations lock in to the tv....SAP in left hand corner 27" glass screen flat

You have to make sure the TV is set to cable not air. Will not look for upper programs unless it is set to cable. SAP needs to be off in the setup menu unless you want it on. Secondary Audio Program(SAP) is for foreign languages.

Instead of explaining the SAP/Stereo function to you, the easiest way to get the TV back to normal is while the set is on press the ACTION and POWER buttons at the same time and hold them until the CHK screen appears. Once that does release the buttons and then press the action button again to exit the CHK screen. Your TV is now back to the factory settings and will need to have the channels programmed again. By the way the SAP/STEREO button on the remote should be near the upper left hand corner of the remote itself.

Some channels have no sound some are in spanish

With your remote, go into the menu, find the audio setup and click off the SAP. Thats the Second Audio Program. Some Broadcasters send a second lanquage along with the regular audio. Someone must have been looking around or playing with the remote and turned on the SAP.. Good Luck PS please do not forget to rate this thread
