Thank you for posting your question on Just Answer! I will be happy to help you with this problem. Can you please give us some more information so I can better answer your questions.
-Do you get anything on the screen when you go to the HDMI input?
Please give me this information and I will be happy to assist you further.
So you get perfect picture just no audio?
Have you tried using the PCM audio output or the STEREO audio output?
Ok your set lacks documentation in a bad way, I cannot get a manual or anything for it. Any way you can post me a picture of the back of the tv where the inputs are? I want to look for something. (if you can post a picture, please click the icon above where you are typing with the green tree on it. This will allow you to upload a picture)
No I was actually hoping to find a service manual so I could look at the audio circuit and how it relates to HDMI.
IS there any red and white jacks right next to the HDMI input on the back of the tv?
Ok well glad you found that! Hopefully you can change out that HDMI cable and solve the issue, let me know if you need anything.
Ok Paul, sounds good I would agree with you on the bad HDMI cable.
Let me know if you need anything in the future.
