My Dynex 1909 has no sound other than a white noise type otherwise all is fine

Denon requires that you assign video to specific ports. HDMI, RCA or any other- you have to select which type and which port and you will get video.

try a new HDMI or try compusite cables they are five cables green blue red white and black or you could try just rca jacks yellow white and black the only problem with rca jacks is it wont be HD but you will have sound and picture

Plug the USB connector into an available USB port.
• Check your computer's volume level.
• Check if your computer's volume is muted.
• Check your operating system's audio input and output settings.
• Check the headset's volume and mute settings.
• Restart computer.

Otherwise, I would recommend pursuing replacement options

Hello Debbie,

This is due to incorrect connections between the dish box and the TV. You may find that if you select another input (AV1) on the TV, you will have sound from the dish system, but no picture.

I suspect you are using an RCA type AV cable with red, white and yellow jacks on both ends. You've most likely connected the yellow jack to a socket labelled Y, Pb or Pr on the back of the TV and then selected the COMPONENT input on the TV.

If you are using a cable with red, white and yellow jacks, please make sure they are connected to the sockets on the back of the TV shown below. I've ringed the socket for the white jack in green for better visibility.




Once you've done this, select the AV1 input on the TV by pressing the INPUT button on the dynex remote, then use the arrow keys to highlight AV1 and press ENTER to select.

If this does not solve your problem, please let me know which type of cable you are using and the model number of your dish box. If you don't know the technical term for the type of cable you are using, please describe it as best you can, i.e. how many plugs/jacks are on each end of the cable and whether they are color-coded.

Hope this helps. If you need further assistance, please reply to me by clicking on "Add a Comment" below your question.

With a Black and White picture it sounds like you're trying to connect the DVD Player's "Composite" connection to the TV's Component Connection.

Composite is a 3 wire system with Yellow for the video, and red and white for the audio. On your TV this connection is located on the side.

Component is a 5 wire system, with Blue, Green & Red for Video, and Red and White for audio. On your TV this connection type is located on the rear panel.

Check to make sure you are hooking the DVD player & the TV to the same input types.

The speakers could be going bad or this could be a sound adjustment issue. Check the Bass and Treble sound settings. It could also be associated to bad connections, but if they seem fine it could also be attributed to cables/wiring.

I had a problem like that so I disabled the tv's onboard tuner (input source)and now we use the cablebox's video and audio out to the video and video in jacks on the TV this will work as long as you have a cable box or sat reciever for your video and audio source and of course your TV must have video and audio inputs so it will work.

Good luck Rich

the starter have someone bang on it while you attemp to start it, or replace it

This type of failure could be in the LCD controller board or the power supply might not be providing enough voltage to the main board and LCD controller.
Let me know if you require further assistance locating the boards or part numbers.

Please stop buying these cheap things.....your out of luck. Parts are not available for these cheap chinnese sets....Thank Bill Clinton. Anyway, sound like the tuner going out. But....you can't get a tuner...Sorry. Just try using a vcr or cable box on video input and change channels that way.
