Facing TV Problems? Ask a TV Technician.
Hello and sorry you're having problems.
Offhand this points to a fault within the TV causing this. Can you please tell me if using the volume buttons on the set itself work to operate the volume?
Also is the sound working right now- or are you saying it's simply gone out, but you can still see the volume icon moving up and down with the remotes?
Do you need assistance with this problem?
