Why is there sound but no picture?

How is the XFinity box connected to the TV ? Channel 3 is only for Co-Ax ("cable") connections - it might be on an HDMI input.

Hello there,

Here is the link to the full manual:

Before connecting your devices...
The signals that enter the TV and connected devices will need to be output in the correct format using the suitable connections. Below are the different types of video connectors. When connecting the TV, use the inputs that are available on your devices that provide the best video performance.
Video performance level Name Aspect Signal transmitted Separate audio connection required HDMI Picture + Sound No DVI*1 Picture Yes

L-AUDIO-R Component video Picture S-Video Picture Composite video Picture RF/Coaxial Picture + Sound No
*1 If the equipment has a DVI jack and not an HDMI jack, connect the DVI jack to the HDMI IN (with HDMI-to-DVI cable and/or adapter jack), and connect the audio jack to the AUDIO IN (L/R) jacks of HDMI IN. (The DVI connector is for video signals only) To enjoy the best visual experience with your system, it is preferable to connect your best devices with the highest quality connections available. For example: your Blu-Ray Disc player or HD Set Top Box with HDMI, followed by your DVD player with Component, then your Video Cassette Recorder with S-video etc.Note: The quality of the picture also strongly depends on the quality of the cable used.
HDMI The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting high definition video and audio signals. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV). DVI The Digital Visual Interface is capable of transmitting high definition video, but does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA). It is possible to connect an HDMI device to a DVI device using a HDMI to DVI adapter. Component video Component video is an analogue connection. It is capable of transmitting high definition signals. Component does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA) S-Video Separate video, abbreviated S-Video and also known as Y/C is an analogue video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one signal line. S-Video, as most commonly implemented, carries standard definition video. It does not carry audio on the same cable. Composite video Composite video is an analogue video (no sound) format. This is the connector you should use if you do not have any other connector available, in terms of quality. RF/Coaxial RF Coaxial Cable connection is used for transferring television signals (audio and video) originating from an antenna or cable box to a Television.

Hope this was helpful to you.
Goodluck

The pecking order for output video to your monitor forbids a lower quality video (composite (Yellow) being up-ticked to anything higher (your component out) (Page23).

The wii would be visible on the Monitor Out composite output (Page 24) to the TV.

I my self don't have that exact unit, but most are similar, and i have looked up the specifications which are:

Inputs:
1 x S-video input
1 x Composite Video Inputs
1 x Digital Audio (TOSLINK) Input
1 x Stereo Audio Input

Outputs:


document.write(neg_specification_newline('1 x S-Video Output
1 x HDMI Output')1 x S-Video Output
1 x HDMI Output
INPUTS (coming from devices to the system):
1) The unit already comes with a DVD player, correct? If so you don't need to connect it. If you do, connect your DVD play via an s-video input, since a normal DVD player doesn't need a higher quality/resolution input.

2) Connect your cable box to the home theater system via a composite cable (the one with Red green blue), if it has composite outputs ofcourse. If not, do it visa versa with the DVD, if your dvd has composite. So make the dvd via composite and cable box via s-video.

3) Audio from the dvd, this would be via Digital Audio (TOSLINK) Input or stereo audio input. the digial audio will give you true 5.1 surround sound, and the stereo will only give you left and right channels, like you would hear from anything else (like a normal cd, radio, etc).

4) audio from cable box, would be again depending what you want. If you cable provider gives you alot of programming that has 5.1 surround sound (mostly HD channels), you would be better off with the digital audio. But if you watch more via your DVD, then connect the cable box via the stereo input. Again, this is to your preference, and which one you want true 5.1 surround sound from. The system should be able to 'emulate' 5.1 surround sound via the stereo cable too, but if your watching a movie, it can't really tell if a sound is supposed to come from the left rear or the left front.

Output:
5)connect to tv via HDMI if available, or S-video.

HDMI is much higher resolution (HD quality) S-video is normal cable programing or 'dvd quality'.

And the Tv would be left on mute or volume=0 since no audio is connected to the tv! All the audio should now come from your system.

Sorry if this was too vauge, but I don't have the same system and dont know exactly what/where all the connections are. If you have any other questions let me know.

HI,you are not getting picture because the yam 363 dose not upscale or convert the picture from the composite input to hdmi.You will have to put a video cable from the composite out put on the amp to a scart convertor into the tv or put console picture into the tv and sound to the amp.

hope this helps.
CABLE GUY.

a switch box is needed the s video shares the red/white audio with the yellow rca that is being used already

Since you have a surround sound system, you probably should just bypass the TV's audio.

Connect the red/white plugs from your digital cable box to one of the inputs on your surround sound system but not the Phono input unless the Phono input lists something aside from Phono, like Aux/Phono or CD/Phono.

Connect the S-Video or composite (yellow) video plug from your digital cable box directly to the S-Video or composite (yellow) video jack on your TV.

If your digital cable box does not have a S-Video (4 pins and flat rectangular hole) or Composite (yellow RCA jack) jack and only has the screw/push-on type cable with the pin in it, then leave the remaining connections as-is.

Now switch your surround sound system to the input you connected the red and white plugs to and turn on your TV. You should see picture from the TV, but hear audio from the surround sound system.

Set your 4:3 to stretch mode, see this link

Is the TV connected to both the DVD and the Cable box via component inputs? I gather the cable box is a HD box? If they both show up through component try connecting them to the composite video inputs (yellow connections) and see if the problem still shows up.
