Do you have the set muted or something plugged into the jack?
SOURCE: No Sound on TV??
I would borrow a set of external speakers to see if I could get sound from the sound circuit at all, if not, then it sounds like the repair shop.
SOURCE: 46" Samsung LCD, no sound output whatsoever
First try hooking up a different source such as a DVD player or Cable box and see if you have audio. If you do then check the audio output from the computer. If you do not have audio then make sure the tv audio is up half way and turn off the set. When you do this you should hear the down chime provided you have the chime turned "on". If you do not hear the down or up chime then the sudio circuits on the Main bd are bad and the Main bd will have to be replaced. A quick way to check to see if the audio circuits are working is to listen for the up or down chime when turning on of off the set coming from the tv speakers speakers.

On the back of the TV there should be a variable audio out this will control the volume level on the speakers or at least it should

It sounds that the sound processing section [digital circuts] are working well, and the fault must be either to the speakers, settings or to analogue audio amplifier section. Make sure that the Mute function is OFF. If it is OFF, and still you do not get audio output by tV speakers, surely the fault must be to audio amplifier circuits, provided speakers are OK. If your TV has a headphone out socket, this socket should also checked for proper interconnection.
