Thread moved to LCD forum to give it wider exposure. As long as your Mini works okay with a VGA monitor, this problem is LCD specific.
I am looking for clarification on how this monitor is wired to a P1900 and a Mac mini w/MacPac harness. Specifically, where are the Accon(red) and the 12v(yellow) connected to. A call to mp3Car had me connecting both the red and yellow to the P1900 secondary ouput(brown) to power the screen. The Mac and P1900 seem to be starting up correctly, but the monitor will not turn on or open. Any help would be appreciated.
