well how do you have your cable box connected, if its through the receiver hdmi you should switch to an optical audio cable and run the box hdmi straight to the tv. Also make sure you are not turning the cable box off, what you are experiencing is a loss of the hdmi handshake when the tv is turned off.
That would mean connecting my Blu-ray to my Cable box. Trouble is the end of the cable that was in the TV has a square shape to it and nothing on the back of my cable box matches that shape although there is a red port labelled audio out but it will not fit in that. Can I send you a photo of the back of these units? Maybe that would help.
You had mentioned home theater speakers. I presumed they were connected to a stereo receiver for surround sound.
The HDMI cables carry both the video and sound so with a HDMI connected to your tv from the Blu ray you wouldn't need the optical audio cable connected to the tv.
Also I would guess that the optical audio from the Blu Ray is a output. It would need to connect to a input and there would be no Audio input on the Cable box either. Don't plug the optical audio cable into the cable box.
Just leave that optical audio cable disconnected and see how things work.
Speakers work but I still have to go through the audi set up to change them from anything but Bypass. In case this makes a difference - the Aux on my remote does nothing, should it be able to control my Blu-ray as i have to use another remote to turn the Blu-ray on?
OK, new development. While waiting on your last reply I found a port on the back of the Cable box - light green and it had a shape that matched the Optical cable end. I plugged the Optical cable into that. When I removed it per your last message, I lost audio. I plugged it back in and recovered the aduio. It is located underneath the Digital Audio port. What did I do?
But I see some of the confusion. I looked up that Samsung HT-F4500 model you posted.
In a earlier post you listed these connections.
My TV is flat screen on wall, with iPhone i took pics, here is what I found out:
1. HMMI on cable box connects to TV - DMI IN
2.Optical cable on Bluray connects to TV - OPTICAL DIGITAL ADIO OUT
3.MDMI OUT on bluray connects to TV - DMI IN (port underneath #1)
The advice I was giving you was based on that.
What you need to do is run the optical audio cable from the blu ray to the Samsung HT-F4500 unit. Unless that is what you were calling your tv. That is a Home Theather system. That is the unit that controls the speakers and what I was calling the receiver. Sorry I should have looked that up first.
So try this setup once.
Optical cable from Blu Ray audio out to Samsung HT-F4500 optical audio input.
Usually people don't connect the speakers directly to the cable box since most of the audio outputs are used to connect to tvs or stereo receivers. The speakers are than controlled by the stereo receiver or home theather system. That is why I asked what the home theather speakers were connected to.
To prevent some more confusion what is the model for the LG tv? I want to look up the manual.
NO - only the LG TV and LG Blue-ray along with my Comcast cable box. As I said, sorry, the speakers are connected to the Blue-ray not the Cable box. I think I'm going bonkers with this issue! Thanks and goodnight.
Hard to explain over the forums especially if a person is not comfortable with technology. These are the links to the support pages for the manuals from LG if you don't have paper copies at home. You can use the diagrams.
If you don't feel comfortable doing this do you know someone who is a bit of handyman/technology person that could help out.
Actually from your original setup you mentioned earlier the HDMI cables are already connected. So those should be good.
All you should need to do is take the Optical Audio cable and connect it to the cable box.
Now the sound only comes inwhen I turn on the Blu-ray remote. OK with me. BUT the only choice I have is "By-pass." Using the 'sound' button on the remote I cannot change to movie, concert, sport etc.sounds. This was where I was before (except for the sound being governed by the blue-ray remote). If I go through all that audio set up as previously described I can get those choices. Now what do you suggest?
