Question about JVC LT42P789 42 in. LCD TV
I cannot get any sound out to my receiver when using other devices such as dvd player, satellite box, etc thought the optical out port. It works only with the built in ipod dock, but nothing else. Any ideas? The tv is a jvc LT42789. I wanted to connect a Bose Cinamate system to the TV but without a optical out signal it will not work.
Unfortunately, there is a limitation on the JVC LT47P789 digital optical audio out. This audio output does not get the signal from any HDMI source. This is described on page 49 of the user manual. The manual is available from JVC here: http://resources.jvc.com/Resources/00/01/14/YA653ien.pdf . There is a similar restriction for the analog audio output from the TV with the HDMI inputs.
If you use the component audio/video inputs on the TV from your set-top cable box and DVD player, then the optical audio output will work. Otherwise, you need to find a way to connect the audio directly to the receiver. Some receivers have multiple HDMI input ports. These then forward the video signal on their HDMI output to the TV. Another option is to connect the analog audio outputs from the cable box and DVD player to the receiver. This may require resetting the Audio output from these set-top boxes to keep from sending the audio over the HDMI cable. With the Cinemate, you might need some sort of audio input switch or an HDMI converter and switch that separates the audio from the video signal.
I hope this helps. Please add a comment with more information about your devices for ideas on how to work-around the problem with this JVC TV.

Mine did the same thing once. I think all I did was hit the setup on the remote, and let it run back through all the channels and then it worked just fine.
I hope this works for you.

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear
I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

SOURCE: JVC LT-32DS75SJ issue with HDMI
1. Turn ON TV
2. Connect PS3 to TV HDMI input
3. select TV HDMI input for PS3
4. turn OFF PS3 if it is ON
5. Press and hold the [I/O]Power button until the PS3 until you get the "HDMI Detected" message.
Also, this TV has a circuit that deactivates the HDMI if the rear cover is removed. It is possible the HDMI may have been turned OFF. This is reset in the service menu of the TV.

I had the same problem on mine. It is a factory defect. It means your HD box that controls HDMI, USB, and RED GREEN BLUE component. Usually the red, green, blue, (720 HD) component is still functional, but the HDMI and USB are shot and can only be replaced not repaired. If your warranty is still valid and you have your receipt call JVC and they will give you the number to a certified warranty repairman. If you do not have the receipt they will not fix it. If you do not have the warranty and decide to repair it yourself or send it out, the fix is not difficult but it is costly. The box is about $1000.00 and the labor varies. The last option is to sell it for parts. If you decide to do this I will purchase the broken television from you. But if you have your warranty info there is nothing to worry about.

I hooked up a Pioneer DVD player to my TV and when I play a DVD the volume cannot be controlled by the TV. It just plays at one level and on the louder side. When I'm watching regular TV and the DVD player is on and playing a disc I start to hear the DVD soundtrack at the same time as the whatever I'm watching on TV. I should not be able to hear anything until I switch over to Video 1. Any suggestions?
