Help with a bad ground????
Ok here is my problem. Whenever my screen is playing a movie or when it gets activated by my back up camera, there is an interferance and it is visible because there are horizontal lines that pass on my Panasonic head unit screen. From what I heard from my friends, it is a bad ground and that I need to check my wiring....Where should I look??? My buddy took a quick look at it last night before heading off to his xmas party and he moved the RCA cables around and the screen went nuts....Please help

Is the engine running when this happens? Try separating the power cables off to one side and the audio cables off the the other side. Try to keep them separate, as you will pick up inherent noise when they are run side by side.

my buddy fixed the problem two nights ago. Took the dash apart and rerouted the wires so there wasnt any interference between the two sets. Now its back to normal. Only thing that bothers me is that its been pretty cold out lately and the plastics on this truck seems to shrink in the cold and it makes all these new noises that I am not familiar with!!

You might want to think about adding another engine to chassis ground, I had the same problem with engine noise, come through my head unit and lines on my monitor..I used a 2 guage grounding wire..It worked great.
