You ARE plugging the Gryphon into the OBDII port with the ignition ON, right?
If so, I think I'm out of ideas and Bill will have to come to your rescue.

To answer your question Jack, yes I am plugging in with the key on. By the way when the problem began and the truck was started after sitting in the heat the Gryphon screen did have some unusual black smears on it which have since dissipated. I wonder if it's possible to "burn" the LCD?? Thanks for your patience with me. I'll hang loose for Bill....
