How do I get audio/sound to work on my LG dvd player. Video works fine

Sounds like from the symptoms that you have plugged the white and red cables into AV3 input on the back of the Teleivsion and plugged the yellow cable into AV1 on the back of the Television.
Check the cables are all plugged into AV1 input ports on the back of the Television. Red and White go into the Audio inputs and Yellow goes in the video input. Also make sure you have not plugged cables into component inputs on television look for AV1 in on back of Television .

The projector has built in speakers.

I do not own a blue ray player but my son has a PS3. The thick cable is most likely HDMI and it should work without the red/white sound cable...try unplugging them so the auto detect feature if available and activated is not trying to compete by finding 2 sources. If that works great! If not, you can get a yellow RCA for the video and just use those as a source - again, don't use the HDMI cable and try it. If you don't have a yellow RCA, I've used another red or white for video testing to see if I can get a video feed. Most newer red/white cable will pass a video signal just fine and are only color coded for ease of hookup.

Depending on what model tv and dvd player you have, it will be either HDMI (one cable for audio/video), RCA Yellow(video) red/white (audio), or Composite (3 for video and 2 for audio). Make sure you connect the cable you choose to the INPUT of your tv and then you have to use your tv remote to change the input (ex: hdmi 1, or aux, video 1 etc) depending on your model and input you choose.

You need 3 RCA plugs... generally colored red, white, and yellow. on the back of the DVD player plug the yellow to video out, the red to audio out (stereo), and the white to audio out (mono). The other side of them goes to the back of the TV... the yellow video input 1, the red audio (R) input 1, the white Audio (L) input 1. Then take the cable service round coax cable and screw it into the back of the DVD unit where it says Coax. Get another short coax cable and hook to back of the DVD unit on Cable out, and the other side to the back of the TV under cable/vhs. And that"s it! Hope that helps you!

from your dvd,plug the yellow to video output red and white to audio output. then plug the other end of the yellow to video input on tv and the red and white to audio input on tv. from tv, plug the other rca cable yellow to video output and red/white to audio output and the the other end yellow to dvd recorder video input and the ed and white to audio input

How to hookup TV

If you have a TV with only a single coax input and you want to hook up components like DVD players and VCRs, here's how to do it.



What you need to connect your DVD player or game players to a TV that only has a VHF/UHF 75-ohm F-connector ("coax antenna input").

1.) RF Modulator with Stereo Audio Inputs.



2.) 6 foot long coaxial cable with male "F" connectors. This cable goes from the modulator to the TV. The modulator also has a coaxial input to plug in your antenna or your VCR.



3.) 6 foot long Video and Audio Cables with "RCA" plugs. The cables connect the yellow, red and white outputs from your DVD or game player to the yellow, red and white inputs of the modulator.





Works with X-Box, PlayStation, Nintendo or other devices that output audio/video via the RCA plugs and you want to connect them to your coaxial only TV.

tcolson,

good day, make sure your RCA red and white marked cable connected to TV screen audio input where you also connect your yellow cable which is the video.

note: always remember color code of RCA cable

yellow = video
red and white = audio (left and right)

connection would always be:

video device yellow RCA socket = TV yellow "INPUT" socket
white and red RCA = TV white and red "INPUT "socket
make sure that all this 3 cable are connected together in a specific "A/V input"

cheers ,

couple of ways but the easiest way would be connecting the video and audio out from DVD (need rca connections yellow red and white)
Yellow --- Video
white and red is audio out left and right.
find in your tv set inputs with similar colors its going to be input 1
or input 2 (as an example)
once you conect the cable matching colors yellow to yellow red to red and white to white make sure you select the same input on your set (video 1 or 2) that its throu input selection in remote control from tv or set itself.

Using the composite video connection method is pretty straightforward. you will be dealing with one video cable (marked in Yellow), and two audio cables (marked in White and Red) Red is right channel and white is left channel if stereo, if mono use the white marked cable. Look at the back of your DVD player you will see the video out RCA jack (marked in yellow) plug one end of the video cable into this jack, the plug the other end of the cable into the TVs Video In jack (marked in yellow) Then plug the audio cables into the Audio Out RCA jacks of the DVD player Red marked cable to red jack White Marked cable to white jack. After this is done plug the ends of the sother side of the cable into the Audio input of the TV white to white, red to red. At this point you should have video and audio once you set the menu of your tv to accept input from the Composite input and the audio jacks. I hope this helps.
