I have direct TV, there is HDMI cable connected to TV. Emery thing is connects via music system ONKYO/BOSS speakers
Even ROkU does not have soun

Customer reply replied 8 months ago
But ROKU is connected via ONKYO System not directly to TV does that make any difference
TV Technician: Anthony_Infotech, Technician replied 8 months ago

OK it should not make any difference however to bypass the audio system too connect up a DVD player DIRECTLY to the TV let me know if its the same or not

Ask Your Own TV Question
Customer reply replied 8 months ago
I reset the settings but still the same
TV Technician: Anthony_Infotech, Technician replied 8 months ago

Then in that case the main-board will need to be replaced is this something you would consider?the mainboard houses the sound amplifier and processing so replacing the board will solve the issue cost of board off hand is around $100,let me know if you want to do this yourself I will provide all relevant info

My SD channels have sound but not HD channels
TV Technician: Anthony_Infotech, Technician replied 7 months ago

If you are using a satellite or cable box pick up the remote to the box and look for the SAP or MTS button, if you do not see it go into the settings menu of the box and look for it there SWITCH IT OFF it would appear this is enabled

Let me know

I am on settings, if I turn Dolby digital off TV vol works fine but the voice come from TV, if I turn it on volume goes off. I have two HDMI cable cables from back of TV, I tried both and both are not working.
Customer reply replied 7 months ago
We have not heard anything from any technician
Customer reply replied 7 months ago
Dish, ROkU and blu Ray are all connected via amplifier to the TV. No volume is coming from Bose speakers connected to amplifier. Does this mean amplifier is going bad?
