Tv has no sound

new batteries. But that won't solve the problem if the universal remote apply other code. when the original remote is applied, you touch the tv icon to be sure you are using the correct parameters. When it still won't solve the problem you go to the ir circuit on the set. the reason may be because of the accumulation of the dust and dirt on the buttons.

there could be a few issues. It could be the speakers themselves. I believe this tv has an audio out. I would hook it up to a stereo and see if it that improves it. It could also be something internal like the amplifier. You have a couple options but I would just use a stereo for sound. If you still need more assistance let me know. Please take a moment to accept and rate my solution accordingly.

I am confused wit the question. Mono is an audio setting. And video setting are for just that. video.

look for MTS or SAP button on remote or in tv menu depending on make--you have it set to SAP--change it to mono or stereo

Go to audio settings window, by entering its menu options. Select the option mono to stereo.

Push the tv menu button on the front of the tv set.Go to Audio setup used the channel buttons UP and DOWN to pick ur choice.Can't do this manually.Try website like Remotes.com to buy an tv original remote.

It's because the TV's audio is stereo and the dialogue is mono split between two channels. When dialogue hits your headphones the majority of the mono signal gets cancelled. Try a different set of headphones or watch true stereo channels... IE movie channels

On the original TV remote press the "AUDIO" button until it gets to the option "MAIN" and this should get the stereo sound back.

Good luck...

I dont know if this will work for you, but its worth a try. I had the same problem.

1. I changed to a station that was having the problem (an analog station with MONO displayed on the screen).
2. I unplugged the TV for about 15-20 minutes. (I was thinking maybe something needed to refresh, so thats why i unplugged the tv.)
3. I plugged the tv back in and voila. The station showed up as MONO then immediately swtiched to STEREO.

After that, i was able to use the AUDIO feature on the remote to actually change from MONO to SAP, etc.

Ive had my Sharp for about 5 months now, and thats the first time its happend to me. Luckily, i solved the problem...this time.

Hope it helps.

Well the default is to obtain the channels signal. most channels over the world their audio output signal is mono. Rare tvs have the ability to save indivisual channel to their memmoty. Read the tv prospectus!!!
