  • First Carputer intsalled and operational! one problem..

    ok i got my p1900 power supply today, i was very excited! threw it all together and had it working within the hour

    one problem that I am now noticeing however (for those of you who read my interferance problem from before, it has been solved with this new powersupply) and that is LCD Interferance.. ive read a few other articles about this but none of it seems to apply.
    I am using a JVC 6.5" LCD with the mac mini, hooked up to composite, this interferance has only started up since i got the powersupply installed, and its maybe just under 2 feet away from the LCD (LCD is in dash, powersupply is behind glovebox).

    if anyone has any ideas on what could be the problem, please let me know!!

    Instead of just posting in here there are forums dedicated to lcd screens and powersupplies. This forum should just be for mac specific issues.

      You do realize that you might get better results with this in the LCD forum, as opposed to the Mac forum. It would only make sense, since it's a general LCD question.

      Are the signal cables running alongside the power cables? Are either of the cables shielded? What about grounding: Is everything grounded to the same point or multiple grounds.
      Have you looked in the FAQ yet?
      How about the Wiki?

        does wrapping the signal cable in tin foil count as shielding?

          No but the idea of your car having wires wrapped in tin foil made me laugh

            Is there a hat to go with that?

                  the tin foil doesnt' work, i tried before on audio cables. you have eliminate the interference not shield it. it's hard to do you have to start to move stuff around and see whts causing it.

                    How's your cable quality? I think you can get shielded video cables.

                      First try a different/higher quality composite video cable and see if that helps. You can also use 75-Ohm coax (RG-6, or RG-59), make sure it's high quality with good shielding and just get the right adapters to go to RCA connectors.

                      Here's a site with info on video ground loops and video interference:
                      http://www.epanorama.net/documents/g...isolation.html
                      It has some links at the bottom for different filters you can buy. But you should try to just eliminate it first.
