Mangavox H2160MW9 Stuck on SAP (Spanish Audio)

Might be the "Original" language selection? Change that to English?

If that fixes it, the program or disc must have Spanish as the "Original" language???

If not, go into Setup > Channel > TV Audio Select and select Stereo?

Look for a "Friends" mode switch. I'm just kidding. There was an episode of the TV show Friends where the TV was stuck in Spanish audio and they couldn't figure out how to change it. Very funny on the show but I know it probably wouldn't be funny if it happened to me... and sorry, I can't offer any contructive advice towards resolving your dilemma.

Is it possible that the TV is set for SAP?

Some remotes have MTS button on them. Hit that twice to toggle though audio services. I know the current digital Samsung TVs have MTS (yes, same labeling as old NTSC stereo MTS it would seem, like SAP, even though SAP no longer exists in digital TV) button and also Curtis brand. For some reason with the Curtis TV on local FOX station had to set the audio over to Spanish to get English program audio again. Even though Samsung said both audio sources were English. ENG1/2 and ENG 2/2.
