No sound from my tv on my home theater system.

Not all Hdmi cables have same capabilities. Check out:

You get surround sound only if you hook up your Optical out from your TV to the Optical IN on the HT-H4500 using an optical audio cable. You may have to buy such a cable if one was not included with the TV or the home theater.

Samsung Home Theater System HT H4500 Home Audio

Hi,here is my simple solution...
to listen your TV on your Panasonic Home Theater System
** you need to connect "Audio Output " RCA jacks or "Optic cable output" or "HDMI out "of your TV
** to "AUX input " or "TV" OR "Any input" of your receiver or "Optic Cable input" or "HDMI input"
** than just switch to respective mode on Panasonic Home Theater System RECEIVER corresponding your RCA or Optic or HDMI connection
.
There you go..Your TV sound is on the Panasonic Home Theater System Receiver..By this means whatever you watch on the TV (TV tuner, satellite , Xbox ..etc.) ,it's sound will come thru your stereo..

Hope this helps!..if more help requires pls let me know.

What kind of TV do you have?
I have found one of the easiest ways to connect surround system is to connect all your accessories (ie. Wii, Cable Box, VCR, etc) to the TV.

Next find the AUDIO OUT on the TV and connect this to the TV or AUX input on the home theater.

Tune the Home theater to the Input that you connected the TV to. This should play the audio through the home theater for any input you tune the TV to.

Note: make sure to turn the TV volume all the way down otherwise there will be some distortion due to the delay between the TV and the home theater.

Good Luck,

can not get tv sound through speakers---can only get sound from dvd

the HDMI cable sends dato TO the TV, it does not have enuf bandwidth to send both to and from, just TO. 

TV has audio outputs, the RCA cable type. If you connect the audio output (red,white) from the TV(look on the back), and connect the RCA cable to Input of home theater system,you should get TV sound from home theater system. You may have to set the audio on the TV for external source. Go to menu, to audio setup, to options. On the Home Theater system, you may have to select the audio source, i.e. audio input 1, etc.

I have a Panasonic HT80 dvd system which plays 5 discs, bought in 2000.

If u have the same or similar he way to get the sound through the recorder is to put the audio output phono leads from the tv to the back of the dvd. On the remote (on mine) there is a button for dvd/tv/ext, oput this to tv it should allow the sound to be transferred from the tv set.

There is an orange button on the remote, half way down in the middle. I belive it has orange lettering and says something like "TV-?" press that, and the sound should start to come through your speaker system. You can then use the original remote that came with your TV and turn the sound off on the TV to use just the theatre system. I noticed that if you use the TV speakers in conjunction with the theatre system, that it echo's.

Is your Panasonic set to monitor the HDMI input? Just like selecting a mode input on the Tv you must also select the mode input on the surround system.
