The output video of my JVC JX-S900 Video Selector has alternating bands of light and dark scrolling up over the original video input (which remains in place and can be seen through the light and dark areas)

On the back of the JVC receiver, there should be a TV input, Coax IN and OUT or AUX input (I don't remember if this model had HDMI). On the back of your TV, there should be an AUDIO OUT, connect this to either the TV or AUX inputs and make sure on your TV, to set the Audio Out is On in the TV menu. Turn on JVC and set input to TV and adjust volume. Another way is using the COAX input and outputs. Connect Output of cable box to Input of JVC, then connect Output of TV to Input on TV.

Yes, on two conditions:

1) the JX-S900 needs to be a proper matrix switcher. It has to have the ability to route 1 input to more than one output.

2) the sub signals need to be low level RCA/phono, and not high level speaker wire connections. That's not just about the type of connector. It's about the signal going through those wires. A low level RCA/phono sub connection conducts a maximum 0.7 Volt. A speaker wire connection can transmit 30 Volts! If you put 30 Volts in to a line level switching device such as the JX0S900 you'll fry it.

Provided that the above two criteriia are both met, then yes it will work.

• Connect the AV receiver's sub out to Source 1 - white RCA phono.

• Connect the two subs mono LFE Left input (white RCA) or the single black RCA/phono inputs to the JVC's outputs 1 and 2 - white RCA/phono.

• Set the source routing: input 1 goes to output 1 and 2

This happens when your output is set to S-video and input does not have S-video capability. If you use S-video do it with an S-video cable (round connectors). Video out (yellow) plus audio out R(red) and L(white) is the alternative or if you are in Europe a SCART.

Hi ,Some info on the JX-S777 is archived on the JVC website,but manual..
You can find it at the URL below:

Since your model's user manual does not available (free ) on the web ,I found one lower model of yours as JVC JX-S555 will help you to figure out to set up..
Pls visit this link as well..

When you have an S-video input you often won't have a feature (menu) selection for that function specifically. The S-video is usually an alternative input for a specific video input. e.g. Video 1, Video 2 and etc. The action of actually inserting the S-video cable will select that function automatically. Make sure that your input matches the video input that you have selected and just hook it up. It will work.

It sounds like you have bad solder connections in the Vertical circuit or the horizontal circuit. The Vertical IC may need to be replaced if resoldering does not help.
You will need to call a good TV Tech for this repair.

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.

hi bro i guss u have to buy new dvd not the rental one might have code on it for recording (copy right ) so u can't record
sorry

The input on your television monitor must be set to view the composite with the S video cable. You will not be able to view the component video unless you also have component video outputs going from the input selector to the television. After you have done that, you will also have to change your television input from "video 2" to whatever input you used for the component video hookup.
