Part of my business includes installing flat-panel TV's. Typically commercial settings such as bank lobbies, etc. I'm not an audio-visual guy, so I really don't know much about anything other than hang the TV and plug it in. I do not get involved in sound, home theater, etc.
Over the last few years I've had several clients TV's lose their sound. As typical, it cost more to repair than the set is worth, which got me to thinking...
Is there a device/box/tuner that will produce a signal, including sound, that can be plugged in to the TV's AUX or HDMI feed? This would enable the TV to be used as a monitor (e.g. - Ch. 3) while the "tuner" and speakers produce the audio from the clients cable or satellite signal.
