Picture ok, Just no sound from speaker, Earphone ok

Check the internal speaker. If it is OK, then check and replace the earphone socket at TV.

Most of these combo units do not have a speaker ON or OFF setting but look anyway.

If the set has a earphone jack that may be the problem--see if works with earphone plugged in.

The socket the jack goes into can get flaky as when jack is inserted it turns the sound OFF.

Also put your ear right to the speaker to see if anything at all is heard--the speaker could be bad--but check the above first.

Hello

If there is no audio output from your tv, either your TVs speaker or its audio output IC has damaged. You just check it with an earphone/headphone, if there is an earphone or headphone socket in front panel of your TV. If there is sound from the headphone/earphone, and not from the speaker, means the speaker has damaged. You have to replace it with same type and number. Just check your set's audio out socket, if any provided, connet it to any external audio sourse, like amplifier or so, and check whether there is sound output from it. If not, your Tv/combos' sound processing IC inside has some trouble.
most common fault is related to sound output IC or speaker itself. If speaker is found OK, go to the sound output section. This section can be easly located as speaker wire goes to that section, and follow it. Before replacing the IC, check its leads for any loose or bad soldering. i advice you to resolder all the terminals of that IC, by applying a little more solder, without making any solder bridge loose contacts between them. If this does not helps, replace the IC with an identical type and number. OK.

Hi there, This sounds like an input control error.
If you find the menu section, then choose Av inputs, you can adjust the settings, I.e. stereo Video or Av (if you are using scart leads then choose Av.
Hope this helps, Chris

Try the remote's "search" feature. If that does not work, then the remote doesn't have a code for that unit.

Hope that fixed ya...
