Why do I have green static on my tv when playing a dvd?

Why is there a loud annoying hum on my TV when a DVD is playing?

  • Check out the links below. These photos are bad - but they are the best I could get. This hook-up is how I finally got picture and sound together but when bright colors are displayed on the screen, I get a loud annoying hum. To get rid of the hum - I have to reduce the color to almost black and white - or else reduce the sound till it's barely audible. Can anyone take a look and help me?

  • Answer:

    You are using an audio cable for for your composite video connection! Also you need to upgrade your interconnects the ones pictured probably came in the box. Replace these with noise shielded cables. see below. Analog video signals need lots of shielding to work properly. All electronic devices emit electromagnetic radiation and will interfere with other devices if not properly isolated from that interference. In this case the color driver is an emitting type meaning signal is not required to blank color information. So with a lot of color signal,noise is inductively coupled to video signal in a common mode feedback loop to improper cable. First change white and yellow cables, if this doesn't work you have a bad cable set and need to replace them. Your connections should follow color code, I took the liberty of picking out a cable set to replace the ones you have for better performance. You may also want to consider a clean power center as this will dramatically reduce the noise induced to your AV equipment thru the power system see below. Let me know if this solved you issue.

I could not tell from the pictures (the jack labels on one were obscured by the cables and the other picture was too fuzzy) but I think your hookup may be wrong and this could cause the symptoms you describe. If you could send us a clear picture (clear enough for us to read the labels) of the back of your DVD player and the back of the TV with NO cables inserted (so we can read the labels for the jacks) along with a picture of the cables you have we can advise you as to how, specifically, the DVD player should be hooked up to the TV. I think a proper hookup may solve your problem.

Low quality cables that connect the DVD player and the TV can cuase this. And so can, an old TV, or a TV that has had a rough life. You either need a new TV, or new cables.

Agree with thinkenstein. Something doesn't look right but I can't tell what's going on either with the cables in the way. Nobody needs monster cables. They're just hype as far as i'm concerned.
