Icons Video-4 icon won't vanish. If I hit "mute" the mute icon appears instead, but as soon as the sound is back on, the Video-4 icon appears and I can't figure out how to make it vanish.

Press the "Display" button. It is the 3 button from the bottom on the right side of the remote.

I Lost picture. Went to press mute button on remote and pressed last button instead. Now i can't get picture back.


If you hit the "last" button again, it should take you back to the channel you were on before you hit the button. when you lost the picture, was the screen blue? black? If you hit the "menu" button, does the menu come up?

My sound is done on the TV- it was working fine last evening and today the sound has disappeared - i may have hit a wrong button- but not the mute one- i checked that alread


Did you unplug for any reason? I unplugged cable box and tv due to lightening and lost my sound when I plugged back in...had to go into the cable box menu under audio and set my output to "Stereo" instead of "TV Speakers"...frustrating, I know!

Volume problem the mute sign comes on but no volume. The caption works


Ensure that your AUDIO MODE is not set to SAP.

Check the AUDIO MENU and confirm that it is either MONO or STEREO.

SAP is the Secondary Audio Program (decriptive video for visually impaired) and will not always have sound on every channel.

Also ensure that your SPEAKER SETTING in the AUDIO OPTIONS MENU is NOT set to OFF.

If it is not simply a setting problem in your menus, then it may be a hardware fault in the main circuit board. If this problem occured just after a power failure or a brief power flicker, then it is certainly possible a component was damaged on the main board and is affecting only the sound.

Please comment back here to this page if you have any questions or just require further general assistance and I will respond as soon as I see it.

If this was at all helpful please click on the 4 Thumbs Up helpfulness rating icon you see on this page.

Thank you very much and good luck.

Hi, i have a lcd toshiba regza LV733N, and i get no audio when connected to pc on hdmi connection. but i do get audio on the same hdmi cable when is connected to my ps3. on a lcd panasonic, both the video...


You must use HDMI 1 port when conected to a PC (to have a picture). Also set the audio in to HDMI not to PC. Look at SOUND/ADVANCED AUDIO. You can use separate analog cable also... Please just read the F manual
