A bios fix would be good. I tried lots of things to diagnose mine including the following,I updated to 1.50 code as soon as I received my game and have had no trouble with the phone screen. When it was updating I had an image on the main screen and the theatre. Perhaps it is something to do with the way the screens are initialised on start up. For those having trouble have you tried disconnecting and reconnecting the VGA cables both when its off and when running? I haven't tried as haven't had a problem myself but if you plug in a USB keyboard there may be a setting in the PC BIOS that may help.
Ran the update again, then went back to 1.13 then updated again
Re-seated connectors both ends
Switched outputs from the pc with theatre screen output, got smartphone video on the theatre screen but nothing on the smartphone
Tried a different VGA cable
Tested for 12v all the way to the smartphone board ( the yellow and black wires )
Reported all this to JJP tech support and they think it needs replacing, but now its happened to Chris too it could well be an update issue ( we previously thought it was just coincidence ) or a screen initialising issue as Aaron suggested above.
I'll leave the bios hacking to someone else
