One HDMI input creates a sound problem - only faint and tinny sound.

Sounds like tv is on wrong input. Be sure HDMI wire or cable input is connected to tv. Look at which input it is on. ( like HDMI 1. Or cable etc. take tv remote (with cable box on ) press input / video button and arrow down to different inputs ( slowly ) until the right input is detected or simply go to the right input you noticed the cable was connected to. Different inputs are there for different sources of connections like DVD. Games. Etc. each work like its own tv channel. Good luck.most times this happens when you are watching tv and press the TV. channel button which will take you to a different tv mode

Hi,Even though you have not mentioned about the cabling connections you have done, for the sake of correct connection I describe all the possible cabling alternatives to you..You can select whichever you want..

TO WATCH DVD ON THE TV:
** Receiver's "AUDIO and VIDEO OUTPUT as " 2xRCA Audio+1x Video " or "Optic Cable OUTPUT or " HDMI Output " of your Home Theater Receiver (whichever you want ,based on the existing sockets and necessary cables on your hand )
** AT TV side : you need to connect "Audio+ Video input s " as can either be : 3xRCA jacks or "Optic cable input " or HDMI IN connector of your TV ,
** than just switch to DVD mode on Receiver and play DVD
*You can use "HDMI" connections as well but sometimes HDMI creates problem on Audio..
TO LISTEN YOUR TV ON SURROUND SYS.
** AT TV side : you need to connect "Audio Output " as can either be : 2xRCA jacks or "Optic cable output" or HDMI connector of your TV ,
** to Receiver's "TV input "or "AUX input" or "Optic Cable input" or HDMI of your Home Theater Receiver (whichever you want ,based on the existing sockets and necessary
cables on your hand )
** than just switch to respective SOURCE mode on Receiver corresponding the connector you have used on the back of Receiver ..
*You can use "HDMI" connections as well but sometimes HDMI creates problem on Audio..

Pls remember.."IN " goes to "OUT" or vice versa..all the times..

There you go..Both Tv and DVD sound are on the Receiver as SURROUNDING SOUND .By this means ,whatever you watch on the TV will come thru your Receiver's SURROUNDING SOUND speakers as well .

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

the hdmi jack on the tv is an INPUT jack, not an output. to use your reciever for tv sound, you have to find the audio output on the tv (most do not have an audio out, but some higher end tv's have a fiber-optic digital out, which may or may not be compatible with your surround sound reciever)

if your tv does not have an audio out, the only way to get the tv sound into the styereo is to use a tuner box, like a cable box or satelite box. tuner boxes always have either hdmi or stereo audio outputs.

to use hdmi with your surround sound, you are supposed to run HDMI OUTPUT from the tuner box or disk player into the HDMI INPUT of the stereo, and then run the HDMI OUTPUT of the stereo into the HDMI INPUT of the tv.

Hello,
There are two things that I can suggest.
1-Test your optical cables to make sure they a good on a known working source because they are very fragile and break very easily.
2-Try to eliminate the use of optical output from tv to receiver. There may be a problem from the HDMI to optical conversion at the tv. Instead, try running the audio directly from the source to the receiver, and let the tv deal with video input only.
Hope this helps,
Good Luck.

Can you tell me which Cable box you are using?Which model/region?

The possibility is that the HDCP handshake could not have happend correctly and hence the issue. Try to connect to different HDMI input of TV from Cable box. If possible change the resolution of cable box and check video

if the Comcast cable box has an HDMI output, it should connect directly to one of the TV HDMI inputs. Then connect the LG DVD unit HDMI output to the second HDMI input of the TV. Use two HDMI cables. Do not buy the expensive Monster HDMI cables. If you have already done so, I recommend you take it back for a refund, then buy the low cost HDMI cables which will work just as good and then you can bank the savings toward a new Porsche Boxter!! Now we have the video connected from both the cable box and the LG system.

Now--what do you do if the cable box does not have an HDMI output--just use its component output and your component cable (red, blue and green) to connect to the TV component input. This will still get the video to the TV and good HD pictures. Hum--do you have an HD cable box? You did not say and I just assumed that you did since you got the HDTV. If not, let me know with a follow up question and I will assist in that area further.

Now for the audio connections--The DVD player will not need any connections since it in the LG unit. The sound will come out the speakers when you start playing the DVD. The cable box is where we get the TV audio to feed the LG unit. If the cable box has an optical output, use an optical cable (again the low cost one)and connect to the optical input on the LG.
This will get the TV audio to the surround system. If no optical output, use the red and white (left/right) audio connections and connect to one of the two the LG audio inputs. To hear TV audio on the LG speakers, just switch to that input or the input associated with the optical input.

To watch DVDs, switch the TV to the HDMI input to which you connected the LG unit. For TV, go to the other HDMI input (or component input).
Switch the LG to the audio input to which you connected the cable box to get TV sound.

Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.

Had similar problems with HD cable on dvd. swapping with another cable solved the problem.

1. This TV has setting for the HDMI input that allows you to select the HDMI Audio or Analog(red/white wire) audio. Make sure this is correct

2. Most cable boxes are DVI not HDMI. If DVI then you actually do need to use those Red/white cables. If HDMI, refer back to #1.

3. The cable box has a setting to select the Audio output, HDMI (digital) or Analog(red/white cables). Just like #1, this has to be set.

4. Contact your cable company to help you set up the box correctly. JVC can probably help you check the TV

See below for the correct setup to get the best clarity sound possible.

From Set top box:

1. Audio: optical or digital coax cable output --> jvc system Input
2. Video: hdmi output--> jvc system input

From JVC System:

1. Video: HDMI output---> TV HDMI input

TV:

1. only accepting HDMI input from JVC System.

This will provide you will sound from your jvc system at all times. Your JVC system is made to be used as a hub. So essentially what you are trying to do is connect all components into the JVC system. Then only connect the video portion to your TV. The TV itself should NOT be emitting sound.

Note: You may need to turn off the speakers in the TV setup menu to acheive no sound from the TV. This will make for the ultimate experience.
