Question about JVC TH-A75R System

1 Answer

No "red light" on Digital In

I wanted to hook up my Surround System with my TV without SCART. The optical cable shows a red light on the end when I plug it in on either tv, settopbox or apple tv, but when I plug it into the JVC it does NOT light up. I noticed that the "port" for the optical cable is enlighted on all devices in red as well, but on the JVC I don't see anything. Do I have to activate it on the JVC or is it possibly broken? I don't have cinche-entries on my new tv to connect tv-sound over these so I really need my digital in-port

The port on the jvc is probably an input, which does not produce light. Only optical outputs will have the red light in them.

SOURCE: I just bought a JVC

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.

SOURCE: We are trying to hook

That cable doesn't exist. You can't just shoot electrons into one end of a copper cable and have light come out the other end.

My $.02...

Treat your TV like the primary user of the Hi-Def Video ONLY, not the source of any audio. Ask yourself, does it really NEED to be in an audio chain if it doesn't tune the station off the air?

Your JVC should be the primary destination of high-end audio, directly from, say, the Cable Box' while the Hi-Def video is sent to the TV.

Zigzagging good audio and video through the room to devices that don't need it is expensive and wasteful, plus it adds complexity and unnecessary connections that add nothing but could fail.

Hi, I have a Funai vhs dvd combo recorder model drv-b2737 and would like to know how I can set this up with my flat screen tv and what cables would I need to accomplish this. Thank you


This has no HDMI socket so you have a choice of either SCART or SVHS depending on what your TV has. If the TV users HDMI you might want to consider a SCART to HDMI adapter lead.
http://www.ebuyer.com/133106-startech-com-6-ft-hdmi-to-dvi-d-cable-m-m-hdmidvimm6?mkwid=sWA3N2WiH_dc&pcrid=51630194939&pkw=&pmt=&gclid=Cj0KEQiAyuPCBRCimuayhb3qqvwBEiQAgz62kTtKa_YG_1esIQiPgik-Xm5AFxuGZI25r11jA5KJOFwaAjJj8P8HAQ

Plug the SCART to TV in the bottom SCART not the top one!
If you just want a SCART to SCART make certain you get the highest quality ones you can find.
There is an OPTICAL output for the high quality sound. You can connect this via an OPTICAL lead to either a Surround Sound unit if you have one or direct to the TV. Again if it has an OPITICAL lead.
If using make certain the output it is switched on at both ends. You will see a red light if the TV is outputting it, with it unconnected to the VCR.

How do I get audio out of 32lc2d to go to the external surround sound system


Depends on your external sound system... If it supports HDMI, then just connect an HDMI lead between the TV and the external amp. If you don't have HDMI, look for two RCA/Phono connectors (small circular connectors) on the back of the TV (should be coloured red & white) and connect these to the external sound system. Finally, if you don't have either of these look for a 32 pin scart socket (rectangular with a bit sticking out) and get a scart to phone cable. Plug the scart plug into the TV and connect the Red & White output leads to your external system - hope that helps :-)

Have you seen the user guide?

http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000036122.pdf

The TV is intended to be an end point of the video, not a source of audio. Many TV's (monitors) don't have ANY audio, much less surround sound capability. Composite Video is theminimalist video connection for setup; Component video to the TV should suffice for viewing DVD's.

Is your TV the SOURCE of surround sound programming (via an antenna) or does the programming come from elsewhere like a Cable Box? THAT would be the source you need to tap for surround sound.

I need to connect a surround sytem to my tv but cannot find an audio out on it


Depending on the TV you have and the surround sound system you can use the following:
An optical out cable.
Headphone jack to headphone jack (a cable with a 2.5mm headphone jack on both ends) you then plug this into the headphone jack in the TV and the other end into the audio in jack in your surround sound system.
You can also use a standard scart lead to plug into your TV and surround sound system.

Hi Martin,

A wiring Schematic is not that you should be looking. What you need is large feeders to understand hot to connect to various ports to give your desired output.

Cant get my viera linked panasonic to play through surround sound


I had the same problem, so i contacted panasonic, I am including the email they sent me.


For connections of audio, so that you can hear all tv audio through the
surround system, connect either an optical audio cable or red & white
analog audio cables from the tv to the home theater. If you are using
optical audio, there is a plug on back of tv labeled for digital audio
output and an input on the surround sound system. If you plan on using
analog red and white, use the PROG OUT red and white output jacks on the
back of the tv to the AUX input on the home theater.

For video connections, to get HD you will need to be using either HDMI or
Component cables. HDMI is the cable that will provided 1080p signal (the
best HD signal), but if the source does not output 1080p, then your tv
will not display 1080p. Most cable boxes output at 1080i or 720p when on
HD stations. This signal still provides great picture quality, but HDMI is
not needed to get these HD signals. You can use component cables for your
cable box and the DVD player output to the tv for video. HDMI might give
you a slightly better picture quality but the signal will be the same.

To make the connection, you will want to connect from the cable box to the
tv (component or hdmi). Also from the home theater system to the tv using
hdmi or the video cables from component (red, blue, & green cables).

We hope this information is helpful to you.

Thank You,
Panasonic Consumer
