I am working on a 2006 model M9 that the LCD monitor is hinged so that the main door can be opened and then the monitor can be opened.  The problem I am having is that when I latch the monitor and then close the main door the touchscreen does not work properly.  However when I leave the main door open the touch screen works just fine.  It is almost as if the main door is in contact with the touch screen because when I am in touch screen test mode the touch screen shows points like it is being touched.  This is happening on more than one of the machines I am trying to get up and working.  If anyone has seen this before and have a solution please let me know.  Thanks
