So the problem is that you're not getting sound from the computer?
What specific cords/connections do you have in place currently from the mac to the tv?

TV Technician: Nathan, Installer replied 10 months ago

Yes I meant you are not getting the computer sound through the tv.

What specific cords/connections do you have in place currently from the mac to the tv?

no hdmi from tv to cable box,,,, tv setting on tv,, no sound
TV Technician: Nathan, Installer replied 10 months ago

You'd need the tv set to hdmi1, hdmi2, etc, wherever that box is plugged in at.

speaker on computer works
on its own,, sound from app from iMac
TV Technician: Nathan, Installer replied 10 months ago

Okay that is a tv issue then,

the setting you mentioned earlier for audio only is to shut off the tv screen and use just the speakers. That wouldn't apply here.

I do have a concern about the vga, because that is video only and would not be able to give you sound in the first place.

But if no sound from the cable box over hdmi either, that is a tv issue, either faulty amplifier or control board.

There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation:
1) Unplug the power cord from the outlet

2) Wait at least 1 hour (60+ Minutes)

3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.

Let me know the results.

Nathan
