I hve an interesting thing happening to an install i am working on.
I put four 15" flip down monitors in a tour bus conected to a JVC 7400 single din dvd player. There are also 8 4x6's in the overhead compartment over the seats. There is no engine noise in the audio... however; the picture has a slight bit of interfearance that looks similar to water in the picture. The louder i turn up the sound, the worse the interfearance gets.
I have changed out the headunits. Changed out the cables. Tried different screens. Ran a new ground from the source unit and screens to the battery. No change. Ran a new power sounce from the battery. Still no change. I even tried a high power 12 amp noise filter on the constant power lead and ground. That di nothing either. I am getting a constant 13.6v and the source unit and the monitors. When i turn off the source unit; there is no interfearance in the picture to any of the screens. And, i am also using a 4 way video signal booster that i have also changed out, 2 no avail.
I am starting to pull hair out of my head. Can anyone offer any ideas that maybe i havn't tried.
Tahnks in advance.

Also, this interfearance is still there even when the bus isn't running.

Try running video to only one monitor without going through the amplifier. If video is clean then, put the amp back in the circuit. Notice the status of the noise. Try not to lose your mind or pull your hair out.
