Help! My husband pressed a wrong button & now all we have is a word 'Mono' on the screen. How do we get TV back? Thank you.

Press the MTS button, or go in to the Tools menu and change the sound settings from Mono 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.

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...

Updating the Channel List Automatically You can update the channel list when the broadcaster adds new Services or if you move the TV to a new location.

1. Press the MENU button to display the menu. Press the ▲ or ▼ button to select "Digital Menu", then press the ENTER button.

2. Press the ▲ or ▼ button to select "Channel", then press the ENTER button.

3. Press the ENTER button again, to select "Country".

4. Select the appropriate country by pressing the ▲ or ▼ button. Press the ENTER button to confirm your choice. Even though you have changed the country setting in this menu, the country setting for Analogue TV is not changed. (Refer to page 11 of the user guide)

5. Press the ▲ or ▼ button again, to select "Auto Store". Press the ENTER button. When it has finished, the number of scanned services will be displayed. The existing favourite channel list will not be deleted when the channel list is updated. To stop the scan before it has finished, press the ENTER button with "STOP" selected.

6. Press the EXIT button to exit. If the signal status is poor, the "No Service found! Check the aerial connection" message is displayed. Check the aerial connection and the try the procedure again.

If the channel icon is greyed out and you cannot tune the channels press the TV/DTV button on the remote control unit so that the icon is visible again and not greyed out. This will allow you to tune the TV.

just spoke to Samsung support and it turns out that the freeview tuner had froze and needed resetting. To do this put TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu. Press the 'down arrow' untill you've highlighted option 12 - 'reset' and then press the 'right arrow' to enter the option. TV will turn off and when you turn back on it will start in 'plug & play' mode as if new. Set the time and country options and then it will perform a complete scan. I've just retuned mine and all back to normal. Hoorah!!!! :-)

The TV set itself will probably have a button that is marked either "Video," "Input" "Source" or "TV/VCR" - I would need to have your exact television model # to be sure. Make sure the cable box is on. Press the Video/Input/Source/TV/VCR etc button and see if your cable picture reappears on one of the source channels. If your television is connected to the cable box with a standard coaxial cable, then Ch.3 or Ch. 4 would be the right choice. If you have a digital cable box, however, the cable is probably going to be on an auxillary channel. If you give me the exact model # of your TV, and the type of wires that run from your cable box to your TV, I can give you more precise instructions. Good luck!

Use the audio select button on the original remote. Press it repeatedly until "mono" appears on the screen.

The link above does not work.

Sound like the power supply with a bad capacitor.
