Question about JVC LT42P789 42 in. LCD TV

1 Answer

No optical output except when using ipod dock on 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.

SOURCE: The screen shows ''Weak Signal'' and no picture.

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.

SOURCE: JVC LT-32P679 Blinking Power Light, Automatic Shutoff

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

Try this

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.

SOURCE: All of the HDMI ports on my JVC lcd tv are not working.

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.

SOURCE: Can't play dvd player on JVC tv; I don't have a JVC remote.

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?

TV audio output vastly different for satellite feed versus DVD feed. Why?

It is possible there are separate sound level functions for the DVD player, the tv and the satellite box, try the different remotes for each by unlocking the volume control on the satellite remote until you get them close or use the device specific remote volume controls. I would also try and use HDMI if available for the DVD instead of composite. If the volume controls are different it will show on the tv, might also go through all audio settings for each device. Some devices are pre-amped or send out strong sound signals while others are line level outputs designed to be amped by the output device, in this case your tv I believe. The HDMI vs stereo audio that goes with composite may be the cause or it could be in the settings of the device. Worst case is to remember to drop volume before you switch back so you don't ruin speakers.

Do not know how to wire my sa-w10 speakers together

For surround sound, you need an A/V receiver with 5.1 or 7.1 surround capability. Depending on what kind of receiver you have, the DVD player, satellite/cable box, etc hooks to the receiver, those signals go out to the TV, and the speakers hook to the receiver. The receiver decodes the signal from the cable/satellite box or DVD player and routes it to the appropriate speakers. If the TV program or DVD isn't HD or coded for surround sound, the best you can expect is 2.1 channel stereo sound. OR, you can hook everything (DVD, satellite/cable box) to the TV and run an optical cable from the Digital Output of the TV to the receiver, which is basically the same thing, just a different way to hook everything up. Hope this helps

I recently purchased a new Samsung Blue Ray player. My previous Sony DVD player used the blue,green, red cords plugged into DVD imput, and I used Coaxial for sound. The Blue Ray only uses HDMI, which the...

Optical carries only 5.1 sound, no video. HDMI carries both video and sound. If your receiver doesn't have HDMI, check your TV for optical output. You can go BluRay to TV via HDMI, then TV to receiver via optical.

If you don't have optical out on your tv, you're going to need either a receiver with HDMI or a BluRay player with component output (blue, green, red).

Getting the best out of my Sony STR DE-475

Yes, it would downgrade.


Simply run an HDMI cable to the LCD from the DVD player. Now, use the digital audio output of the DVD player to run to the receiver. I know the Sony has an optical input which i recommend over the coaxial input as the optical cable doesnt waste any energy as a medium transferring sound since its only light.

I am using an HDMI cable on my STR-DG710 and get no sound

A lot of devices like PS3, HD DVD Players, Cable boxes, etc., require you to define on the setup menu if sound will be coming out of the HDMI cable or not. Most of these devices can be set to HDMI Auto, but not all of them do.

I currently have both my Blu-ray and HD DVD player outputting both video and sound through my HDMI into my STR-DG710. Both devices are setup to output sound through the HDMI.

But like the other person on here posted, it you have a DVI to HDMI cable, you won't be getting sound. The only device that will output sound from a DVI to HDMI are select computer graphics adapters like the GeForce 9800 GT series video cards, and even not all of those will have this feature.

Hope this helps.
