hey all,
i've just put my laptop and touch screen in, but i am getting all sorts of interference on the monitor. the picture comes through and the touch screen still functions.. but there are lines moving up the screen etc.. but only when the laptop is running of the dc power supply. when i unplug the laptop from the cigarette lighter and have it on batteries the screen works fine.... also i tried using an external battery to run them and found that if i power both the laptop and the screen of the external battery theres interference, but if i power 1 off the car and one off the battery it works fine.... any ideas?

I have the same problem. Did you figure it out?

yeh i fixed it... the problem was the dc power supply... i switched over to using an inverter and the ac power supply that came with the laptop and it all works good now
