LCD Feedback Problem

Pinyix · 01-22-2007, 07:36 AM

I have a 6.5" Farenheit monitor in my car. Whenever there is vibration, there is feedback on the monitor like a bad TV single. Mostly horizontal lines moving from top to bottom with the frequency of the vibration (which could be the engine or the stereo). I moved it off the shabby ground that was the stereo bezel to a ground the car had in the engine bay, but then I got constant feedback when the engine was on and still got stereo feedback when it was loud enough. I have it electrical taped to a large cylinder that spans the back of my dash. I'm no longer getting engine feedback but I am still getting stereo feedback when its loud enough. Am I missing something? There seems to be no place I can ground this monitor well enough. I plan on drilling the cylinder ground to make it more permanent but I don't think thats going to do it. What do you guys think? Could it be the S-video connections?

Hmmmm....there can be many variables. How is your monitor connected for power and how is it connected for a video signal, s-video to compouter?

If its only getting interference from the stereo being loud, it seems to me like a grounding issue. Powering it from your computer's power supply should do the trick.

I would double check your video connection for a lose connection or maybe its touching something.

I actually don't have a carputer yet, the monitor is connected through an s-video to a DVD player headunit. I'll try taping off the s-video wires.

Hmmmmm......it could most likely be a bad power source for the monitor.
