My tv got no sound..but if connect a video/dvd via rca ok.

It sounds like you have got the cables mixed up. You need to plug the output of the modulator into the aerial connection on the TV. The idea of an rf modulator is to let you connect a source into a TV via the antenna connection on the TV.

Hi,here is my simple solution...
To listen your TV on your samsung ps wx30 surround sound system ,
** you need to connect "Audio Output " RCA jacks or "Optic cable output" or "HDMI out " of your TV unit
** to "AUX input " or "TV" OR "Any input" of your dvd player or "Optic Cable input" or "HDMI input"
** than just switch to respective mode on dvd player corresponding your RCA or Optic connection or HDMI ..
.
There you go..Your TV sound is on the dvd player By this means whatever you watch on the
TV (tuner, satellite , Xbox , etc..) ,it's sound will come thru your dvd player.

Hope this helps!..if more he?p requires pls let me know..

Mainboard (AKA tuner board) is the issue. It was lost with the DVD input plugged into the mainboard. IF this happens again, I would recommend unplugging the internal DVD and go with an external option. These combo tvs are confused because of the extra processing power needed for an internal combo player.


Thank you!

Ok, this seems to be a common problem amongst us techno-phobic couch potatos ( just kidding), sounds like tv input is not selected on right channel input. make sure pins on s-video are not bent or missing, if they are, you need a new s-video cable, try connection through the red/white/yellow cables, make sure that you have correct input selected on tv set ( example: S-video, component1 , aux 1,HDMI1, and so on.) put dvd in player and keep going till you get the right one. in ,my experience, the R/W/Y cable is component1 and of course, s-video, is well, s-video, kinda self explanatory...

Hello,

This is how the connection is suppose to be, DVR "OUT", to TV "IN" using the RCA plugs, then press AV on the TV. If this is how you connected it, then maybe there is something wrong with the video wire (Yellow).

As for the DVD, you need to connect an Audio wire separately because the component Red + Green + Blue wire only stands for video. Audio is Red and White, this must be connected for you to get sound from the DVD.

To connect the Audio for your DVD player, connect Red and White wire to Audio "OUT" of your DVD player, to "AUX" in of your AVR 146 receiver, then select AUX on your receiver and sound will come out from your DVD through the receiver.

I hope this is not complicated for you. This connection is simple, all you need is to understand the basics which is OUT and IN. If you want to watch DVD on your TV, this means the DVD will be good OUT to IN of the DVD. The same goes for audio.

If you don't understand, please let me know so that I can direct you further.

Good luck.

connect audio output (RCA Jack white n red color) from the video, to the audio input of your TV. Make sure you use same AV channel for the video and audio.
i.e AV1 or AV2 or AV3

The cable box IS an external tuner.  You should connect the video output (either S video, HDMI, or component video) of the cable box to the video input of the DVD.  Then connect the audio output of the cable box to the audio input of the DVD via stereo RCA cables.  If your tv monitor has multiple inputs (ie: video 1, 2, and 3...) connect the video and audio output of the DVD to your tv monitor using an alternate video input (if cable box goes into your tv thru video 1, connect the DVD to video 2).  If your cable box only has one output, or your tv has only one input, then just connect your cable box to the DVD as above, and connect the DVD to your tv.

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

the problem sounds like its with the s video connection, try using the composite video input

Do you have both video and audio cables connected? Yellow or S-Video cables are only for video, you also need to connect the red and white RCA connectors on player and TV for stereo sound.
If you have already done this, check the player's menu to see if there is a setting for external or auxiliary audio.
