Re: Picture but no sound
If it was on a digital channel, check your cable connections again or rabbit ears and re-aim. flashing blue and what not--blue is alternative 'friendly' display instead of STATIC. On a digital channel, instead, you'll just start losing the sound or the picture will pixelize if not go out completely. Try another channel/source.

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

One of the function keys (not certain which) mutes (and unmutes) the audio. Should have an icon picture of a speaker with a line through it. Alternately, on your taskbar there could be a similar icon... click to toggle. Another option... go to control panel, sound, and unmute. I hope this helps.
It appears you ve discovered the sound task levers required to adjustment properties. Your Tv can still move levers even when the volume is set to mute. Select the unmute button before any voice or audio would be reactivated. Assuming that seting the TV on mute has predominant integrety over the volume functions where not unmuting usually with the same button on the remote would not achieve accessibility to the volume functions. refer to the TV user guide for diagnostic audios. Good luck
Page 26 of your manual: Muting the Microphone In open the slide, you can mute the microphone during a call by pressing the left soft key [Mute]. The handset can be unmuted by pressing the left soft key [Unmute]. When the handset is muted, the caller cannot hear you, but you can still hear the caller.
Hope this helps, let me know if I can do anything else for you. JimmyC
Mute Function and other sound adjustments from page 21 in your manual. The Mute Function prevents the transmission of your voice to the caller. To quickly activate Mute touch Left Soft Key [Mute], then to unmute touch Left Soft Key [Unmute].
Hope this helps, let me know if I can do anything else for you. Don’t forget to rate me or leave a short not. I appreciate it. Thanks. JimmyC

Call your muted A747 from another phone.
Answer the call.
On your A747 select Options with the top left button.
Select the first entry, Mute/Unmute.
This fixed the same problem on my A747. Before doing this the Mute/Unmute had no effect. After doing the repair, all is OK.
